Since the 5800 and the N900 use the same battery, would this work in the N900? I'm ABSOLUTELY excited about this! getting near 2000MAH!

I have wondered if you could do something like this without hurting the phone. I upgraded my G1 battery from the standard 1200mAh to a 2300mAh and did not notice anything negative.

Is there a reason NOT to do this?

It's OEM sized.... That's what tickled my fancy.

Uhm, so how have they supposedly managed to make it 1930mah on the same battery technology and the same space? Sounds pretty dubious... And is the manufacturers name supposed to be "Original"... And the sale packages design is copied straight from Nokia.

Yeah, I know. It's what makes me wonder.

You've never heard of Original? They're the best battery makers out there! LOL.

I know it sounds really wako, but I was looking online to find some more BL-5Js (local) and that one came up as the second one! I am seriously considering buying an extended battery for the N900 when they become available (with the appropriate back). But hey! If I can get an OEM sized extended battery (if they ever really come out) then I'm all for it!

I wonder if there is an app to check the MAH of a battery for Maemo... I wouldn't mind testing it out. It's not that expensive. But I'd need an app to test out the MAH used.

NiMH AA batteries are available with capacities from 1500 mAh to 3200 mAh, so I expect that Li-Ion batteries may have some variance in capacity per cubed millimetre as well.

You can sometimes find the exact same battery sold from different places with very different specifications. There is some variation, but sometimes the shop just chooses to stretch the truth far too much.

The 1150mAh battery I currently have in my Palm PDA can sometimes be found advertised as 1500mAh, which is way above what's possible. People have measured this particular battery to vary between just above 1000 mAh to around 1200mAh.

So this leads back to my question:

Is there a reason to or not to use a battery with a higher mAh than the retail battery?

When li-ion/li-poly batteries go bad they go extremely (violently) bad. So, I tend to trust vendor-original batteries more than unknown ones. Some 3party batteries don't have the very important built-in protection circuit, for example. So, without knowing for certain, I won't trust them. But that's just me

No, if you can verify that they truly have a higher rating and comes from reputable producer.
