Tired of replacement batteries - want the final solution
 

Sorry about the stupid question: why hasn't any company developed a power source that would permanently replace BP-5L batteries for my Nokia N800? Is that technically difficult or too costly? I would gladly pay $ 50 for the freedom of not needing to buy the replacement batteries once every year or so.

Besides, these N800 seem to last for ages, don't they.

Re: Tired of replacement batteries - want the final solution
 

Once a year? Really? I bought my first N900 second-hand in June 2012 and I still use it with the same battery it came with. I find it hard to believe the N800 would be so much worse on the batteries.

Re: Tired of replacement batteries - want the final solution
 

I´m still on my first battery for my n900 pre-ordered from nstore and delivered first day 2009. The battery time isn´t the best now but its working.

Re: Tired of replacement batteries - want the final solution
 

count me too. Bought my N900 in late 2011 and still using it with the battery it came with and it was also a used N900.

Re: Tired of replacement batteries - want the final solution
 

Just because this story seems to be inconsistent with other's experiences I am interested to know if those are Nokia batteries or coming from some OEM like this:

Re: Tired of replacement batteries - want the final solution
 

it was 3 month, since i replace my original battery. still function but not perform good. i replace with battery "flash power" i don't know where is nation that producing it china maybe. ( not be mention in package )

first time i use it, it show only 1150mAH. albeit on the package said 2800mAH. then i try calibrating it using "estelle battery calibration guide" then it show real capacity 1596 mAH. not bad :D

Re: Tired of replacement batteries - want the final solution
 

For the n800 ...I think in all my years I had to delegate 1 battery to "always plugged in " state for the studio...since it finally got to a fully charged level of only under 2 hours. Other than that one battery (which was the original I got +7yrs ago and used every day since)...all the rest of my bp-5l batts are perfectly fine...had them more than 5 years and all show 7 hours.
I do heartily suggest if you have batt consumption issues with the n800 .
1- get proper OFFICIAL OEM bp-5l batts.
2- install cssu, asui, and diablo turbo
3- tweak your power settings
there is no reason you can't have 7hours active/ 10days standby.

As a side note....
I sure wouldn't mind (and I'm sure others as well) having permanent power by wiring and bypass the need for a battery.
Perhaps a cash bounty $$$ would be good incentive to seeing movement and getting it done.(If it can be done... that is...some serious wizardry will be involved for sure....power fluctuation, surges etc...will be an issue for a start...the device wasn't really built for direct wiring ....)

Re: Tired of replacement batteries - want the final solution
 

@supergaban, a LiIon battery of BP-5L size claiming to be anything over 1500 mAh is a dead giveaway. It is just physically not possible to squeeze that kind of capacity into something of that size without inventing a completely new technology. It is a fake and you are lucky its real capacity is what it is.

Re: Tired of replacement batteries - want the final solution
 

Yup.......veeerrrry lucky. coulda' "boinked" your device.
I steer clear of nxx0 batts. that don't state the proper specs....
let alone "look" different than the proper batts.

I bought some n810 "wannabe" batteries once...they even "almost" looked like proper ones...
but there were visual discrepancies...
the batts. were garbage power-wise.
They can do serious harm to your device too.
Stick to official OEM's my best suggestion.
Or let's find a hardware wizard shovel some coin at him/her to come up with permanent wired solution ...wouldn't mind that (again...hint-hint! :D)

Re: Tired of replacement batteries - want the final solution
 

From the n900 battery thread (one of the gems on the boards), many of us had good experiences with Polarcells. They advertised a high but plausible capacity, and testing showed they delivered.

They make BP-5l batteries.

Re: Tired of replacement batteries - want the final solution
 

actually you are right...
there is an exception to non-oem batt's
yup...the polarcell would be the only other option I would safely use.
forgot all about them...
they tend to be pretty consistent with their batteries.
I have one as one of my backup batts for my n900...
not used it much...
I haven't tried the bp-5l polarcell ...but imagine it would work just as good.

Re: Tired of replacement batteries - want the final solution
 

Wouldn't trust my device with this bestbatt alternative.
let alone any other ...
sans the polarcell which was mentioned ...
that would be the only non-oem batt I would try.
Even proper oem used bp-5l batteries that have been rejuv'd and rejuiced will get you 94.5% capacity when fully charged (they lose a bit of the top capacity when rejuv'd )....still at the 7 hr in use/ 10 day stand-by ...I've bought a few rejuv'd batts..for the n810....under $10 each with the shipping...work great...no complaints.

Re: Tired of replacement batteries - want the final solution
 

Nokia Phones have good battery backup.

Re: Tired of replacement batteries - want the final solution
 

That's a tad cryptic....

WUT!
Naw... :D

I was wondering what you were asking for, since I run my N800 from the wall wart most of the time. Then I had a crazy thought and popped the battery out of my running device - and surprise! It went dead. All these years I had no idea it only worked off the charger with battery installed.

Re: Tired of replacement batteries - want the final solution
 

Yup...
Old Bessy is great...greater still would be making her battery self-reliant...sooner or later batteries will stop being made for her...and I know I'm not the only one who will be upset when that happens.
Her days will truly be numbered then.
I'd like to see (if possible) even a dummy pass-through battery that is just a "form" (so-to-speak) to take voltage fluctuations and surges ...like a "breaker switch"...and as well to fool the internal protocols ....and so continue using my lovely n800... possibly even the n810..if such a thing can be done for the n800 it can be done for the n810....hell they have "pass-throughs" for electronic cigarettes ...they're common enough...(they plug the pass through into the battery and into a usb port (computer or wall socket port) and puff away without really utilizing the battery charge)....the thing is whether it is do-able for the n8x0....

Re: Tired of replacement batteries - want the final solution
 

Oh come on, OF COURSE it is doable. It's just a battery, FFS. It has just two contacts, (+) and (-). Connect a simple 4V regulator to those two contacts and you are set.

Re: Tired of replacement batteries - want the final solution
 

I recall someone attempting/ doing just that...
can't remem. the thread(s) ..
There was something else though...some difficulty....it wasn't exactly just that simple ...can't remember what it was though...

Re: Tired of replacement batteries - want the final solution
 

When all else fails, use something like this :)

Re: Tired of replacement batteries - want the final solution
 

Is that a battery or a firecracker....?

Re: Tired of replacement batteries - want the final solution
 

Hahahahahaha
aw crap man....
it looks pretty bad man...
it looks like either a homemade bomb you'd be tackled for at the airport (at best)
or a shot gun shell that hasn't gone off yet.
I don't mind the exposed wire,
I don't mind the bulky cylinder (mind I liked the altoids version https://www.kickstarter.com/projects...le-usb-charger )
but the red packing tape is just the nail in the coffin.
Speaking of which I loved that one comment ("...looks like it'd give you cancer yesterday...") .
The only thing that would be a redeeming quality is if this were be included to enhance the overall "feel" of the contraption...then...I'd definitely go for it.

Re: Tired of replacement batteries - want the final solution
 

I replaced my stock nokia battery with polarcell batteries in my n810 and with no extra software adjustments as mentioned and it lasted all day...all of my day anyway...at least another 2/3hours..on stand by seem to drain much much less too.can't recommend them enough..im sure there available for n800 too

Re: Tired of replacement batteries - want the final solution
 

Welcome new guy! :D

My mention of diablo turbo, asui, cssu and cloning is valid...
especially for those individuals with older batteries that haven't gotten up to speed with having the most recent n8x0 setup.
The benefits of which massively outweigh not updating to the most recent setup. The least of which being longer device lifespan.
The only reason to have a pristine untampered diablo (or chinook) install is to test with or to clone to card with.

If you are using stock diablo os2008 with a brand new polarcell...
You aren't getting the most out of your battery...you are losing (hummm).... ...half a day's worth of additional battery charge (in use time...more in standby)...( roughly ) you could have. That is the gain of the tweaking.

My best suggestion for new people to the NIT is:
1-Install nothing yet until you do these steps 1st (makes it easier to troubleshoot errors from a clean install also less chance of conflicts).
2-If you have installed stuff...reflash to a pristine diablo state.
3-by enabling maemo extras (the benefit there being that enabling this repo. will allow you to install a ton of programs you normally can't otherwise... as well) install rootsh. Application menu calls it xterminal. If you are unfamiliar it. It gives you a lot of power over your device and system.
4-next install penguinbait's console tools v1. this allows you to do a hellava lot of stuff ...least of which is stupid easy thoughtless multiple choice format of partioning, formatting, os cloning to internal or external card, and os backup to card or usb, and that is just a tiny bit of what it can do...very very helpful for people new to n8x0.
5-clone baby clone. Then install asui, latest diablo cssu, diablo turbo to the diablo clone on the card...(the tweaks patches and fixes make it well worthwhile.) Then install gronmayers repo list. (sooo many programs now :D)
Away you go ...(well there are a ton of more cool things to optimize... but that's the basics)
(Me ...on one of my n810's I got a pristine diablo on device (I never use since cloning) and a 32gb class 4 card with diablo turbo on one partition, debian on the 2nd, and mer on the 3rd.)

Sure you are getting a day out of your brand new polarcell on stock os2008.
I get that with normal daily usage with all the updating to the latest os and the patches and power management tweaking ...
the difference is you are using a brand new polarcell.
I'm talking about my using refurbed rejuv'd original batteries (some with a charge of between 70% and 90%) all that are no less than half a decade old and that have been in use daily ...and I'm getting the same output as you.
If you get up to speed ...
you'll be able to do alot more with your device...
it'll feel a 1000x more responsive...
you'll have fewer probs....
it'll save you alot of wear and tear on your device in the long haul...
you'll utilize the optimum of your battery's charge ..
and you should be able to go a lot further...alot longer on a single charge with your brand new polarcell ...

technically... with a new polar ...with the tweaking... you should get at the very very very least...with your device running full-out... 10 hours of constant use (depending on how intensively draining the programs are of course) ...at the bare minimum....
technically ...your battery monitor should be pushing the ceiling for a while before you start to notice a drop in capacity/ time remaining.

Re: Tired of replacement batteries - want the final solution
 

hehe best solution i use it most of the time and there are just a couple of brands that dont work without the fking bsi ...i hate them

Re: Tired of replacement batteries - want the final solution
 

To the op
if you want it that bad then the simplest of solution would be to attach wires on the contacts secure the battery bay with some foam and find a empty place somewhere to put the female conector or stick it to the side of the device and use a usb charger ..of you go
btw the better solution woud be creating a fake battery yourself out of carved antler and placing electronics inside it !

Re: Tired of replacement batteries - want the final solution
 

Hhahaha...
was that a hint nokiabot?
:D

That ain't a bad idea....y'know...
'tween now and march I'll muddle with it and see what I carve up with.

Re: Tired of replacement batteries - want the final solution
 

hm ...out of curiosity what brand / make 4v regulator would be the best suggestion for NIT's ? anyone? Don't particularly want to do voltage experimentation ...(not my forte really...)... and fry devices needlessly...

I think I will muck around with making a built-in unobtrusive permanent power supply option...I'll carve a proto-shell...(stupid plain and simple...much easier for ) something that can be easily copied for those who want to go a similar battery-free option...

Re: Tired of replacement batteries - want the final solution
 

haha i knew it ! you are carving to carve ....
i put up a �0…3 besides antler and you know that this stupid phone somehow removed it :D btw the thing is the proper knowhow for the needed electronics and yes i know how to do it (have done actually) but i feel i am not worth recommending without proper advice.:)
stay tuned....
me too tuned for what you come up with !

Re: Tired of replacement batteries - want the final solution
 

bloody hell...nokiabot....can't resist...
yeah...I can't help mucking about with something new. :D

IF:
1- the regulator (and necessary parts) can be equal to or less in thickness than the width of a standard Nxx0 battery....

2- I have said parts in hand... lined up precisely where they need to fit... so I can efficiently do the work properly, exactly and quickly ...

3-yup there is then no reason why I can't carve 3 antler dummies for the n800, the n810 and the n900.

4- At which point all three can be sent for casting in a cheap high heat resistant resin...

5- Stupid easy then...
A- End user only needs same (affordable, available, and exact) parts that fit ...
B- Pop them in the obvious vacant spaces on the dummy cast...
C- Drill / cut a usb port hole on the device removable back...for utilization of permanent usb power option
D- Make sure there is plenty of wire length from dummy battery to the back to facilitate the normal easy removal of the back from the device (since mounted port connection on the back) OR make the
usb power port hole on back slightly larger..pop in a rectangular rubber ring to easily pop the usb port on or off (depending on the individual desire to use it with a proper battery ..while they still exist and are usable...or with the dummy battery as a permanent power option until the crack of doom, the moon falls into the ocean, or electricity as we know it fails utterly....)

6- For the end user....the production cost in resin is miniscule...... the Nxx0 device line now becomes power supply self-reliant....like all proper computers should be ...

better even.......
(since (and correct my lack of proper electrical education here if I'm off) now that there is proper power regulation to the device via standard usb....(technically wouldn't it be logical that any type of plug-in-able power bank and /or subsequent global-marketplace-common / standard-usb-connector devices and methods of charging said power bank...solar, outlet, wind-up, kinetic etc...(are everywhere nowadays and affordable to boot )... that it would be also feasible to charge said external bank while device is in use...

so it stands to reason that 24 hours ...7 days a week your device could keep running without stop...regardless if standard electrical power goes from a blackout or not. (I know it's plausible since I almost have a full 24 hours of solid use with my solio classic ... solar during the day and then...once dusk hits working off the solio battery... and then when the solio battery empties... finally working off the n800 battery... :D
trick is ...the solio classic line ain't young anymore and like so many other power option devices for the NIT ...eventually there will come a time when nothing is compatible...especially with the older n8x0 original power port...)

making an affordable , easy to install and use, globally common power option now ...
(while we have the luxury of time and foresight to see it coming...)
safeguards our power options in the future before that window closes...

Bluntly...What I'm saying here is...
we can either create the option for our older devices' continuance into the future or...
we willingly give up that freedom when the very last compatible battery is sold....
then it's just borrowed time after which... literally....
the lights go out for the Nxx0 device line.
I'm not trying to instil fear or terror or doom...
the process... It may take a bit...but our devices are tied to the damn batteries...and that means we are tied to suppliers...suppliers who stop making old batteries eventually and move on to more lucrative contracts that have more people in need of plenty of batteries for newer devices...just the way things are...
So it is a choice... we have for now... time to make...but not forever.

OR
...if no one else is interested in this...
I'll make the protos ..post schematics, dimensions, blueprints, whatever...y'know ..the results..
I most certainly want this kind of seamless internal (sans-external-plethora-of-exposed-parts-wires) battery-less option...I see the need for it... at least for my own devices future continuance...

Re: Tired of replacement batteries - want the final solution
 

hum-hum-humhum...
well...
found
10 uf microfarad capacitors of which I need 2 ..one for input one for output...
http://www.ebay.ca/itm/10pcs-50v-10u...item338a3baae4

found the .1 uf ceramic capacitor I'd need too...
http://www.ebay.ca/itm/360693274546?...84.m1436.l2649

And I can find plenty of 5v voltage regulators...like...
http://www.ebay.ca/itm/3-x-LM7805-L7...item3a67f15482

But try to find a lm7804 (4v) voltage regulator (small enough) anywhere...? Not so easy...

Of course I am no electronics wiz ....in the slightest...
I do believe I am roughly on the right track...but I'd rather be certain...
ESPECIALLY with wiring stuff up...
I'm more of an explosions, lotsa coloured smoke and ever expanding foam blowing out the doors and windows kinda mad scientist ...
Not really the electrocution-with-the-sparks-and-the-convulsive-uncontrollable-shaking-smoking-and-then-PERSONALLY-exploding-kinda-mad-scientist...

There is a reason why the massively obvious switch is way over on the other side of the room when Igor throws it y'know... :D

Re: Tired of replacement batteries - want the final solution
 

Just buy a Pisen 1400mAh battery. $10 to anywhereintheworld

Re: Tired of replacement batteries - want the final solution
 

@endso,
You have at least two options:

1. Use a 5V regulator and wire a diode in series with its output. Silicon diodes have about 0.6 to 1V forward voltage drop, depending on power rating (power diodes have a bigger drop). That should reduce your 5V to just the right level.
   The trouble with this solution is that the drop is non-linear. The stated 0.6 to 1V is the maximum drop, if the current is large enough. For very small currents it may be much less. What is "large enough current" depends on the diode, but as a rough guide, assume ~1mA for low power diodes.
   Better try it with a dummy load before exposing your precious to overvoltage.
2. Use a 3V or less regulator and wire it up to give the desired output. You will need two resistors. Connect them in series. The top end connects to your regulated output, the bottom end to the ground. The middle end now provides a reference voltage somewhere between the two, depending on the relative proportion of the two resistors. Connect the regulator's reference input (the pin that normally goes to the ground) to this middle point and hey presto, your regulated output is raised by the relevant value.

There are of course gazillions of other solutions but these are the simplest.

In case I am expressing myself very clearly, here is a page that is:

Re: Tired of replacement batteries - want the final solution
 

@independent - I have a veritable ton of batteries for all my Nxx0's ...
that really isn't the issue....
1-When batteries for the Nxx0 device lines cease to be made what then?...That is the last hurrah for our devices then. They are bound to the batts. just to power them on ..forget even running them 5 minutes let alone a day...we are completely at the mercy of "must-having-the-exact-battery-type" forever otherwise...and it is laughable that 5-10-20 yrs from now I'll be able to find a proper batt to use on ANY of my Nxx0's...However it isn't laughable that I won't be using my Nxx0's in 20 years from now ...I've been using a few of them for what ?...7-8 yrs-ish? .. so far quite happily....what's another 20 yrs to my lovely n800's or n810's?...

-For me...It's also about seeing if I can do this... afterward do a vid showing exactly how to do it easy-peasy ...post it...

-AAAANNNNDDD I get to piss around and make a stupidly high-heat resistant dummy-battery form to house the electo-bits outta deer antler ...that is reason enough right there.... :D

@pichlo
ah! thanks pichlo! :D
I'm sure you have just given me the 1st two to three years of electrical engineering right there :D
Ok....I do have a couple projects I need to wrap up 1st...
So...In the new year... February in fact ....
I will be starting down the road to self-determined electocuticide ... :D
'tween now and then I'll get what materials I need and bone-up on what I need to do...following your advice pichlo...
Come Feb when I start...I'm sure I'll have more questions then...

Re: Tired of replacement batteries - want the final solution
 

I pondered this issue with respect to the neo900 - but then looked at eBay etc and see sellers still peddling batteries for phones far older than the n900. And there are other phone models that use the BL-5J, so that should help buy some more time.

But your point stands in principle.

Re: Tired of replacement batteries - want the final solution
 

yea...for the n900 it's still got plenty of time...
and I do love the neo for the option of running without battery and simply plugged in...huge plus for me.
but I do feel the weight of years pressing down on the n8x0's ..
and having accessible new battery options can't last forever...
also I'd mess with one of my n800's and one of my n810's 1st...
ever before attempting it with my only n900...

and yea...it is mainly about "being able" to do it at this point...
rather than having no choice but to find an alternative ...yet.
What's the bare-bones of that line again?
something like...
"Heaven is options... Hell is none or only one..." ?
I'd rather have the option than none at all...

Not to mention....
there'll be exciting flames, melting things, explosions, pretty bright flashes and bangs that will make me "oooh" and "aaah" and keep me entertained along the way in the process I'm sure... :D
