There was a thread on this a few weeks back if it helps any....i bought one of the £5 ones from amazon and have been using it as a backup for when i'm away from home (a lot with work)...i don't use it often, or all the way to empty but just until i can recharge the original (so bought a desktop charge for £3 from ebay)...it works perfectly for me this way.

i cold take a dump and put a BL-5J sticker on the steaming pile, doesnt mean it would be good for your $600 phone

true..but it might be the most useful thing in the vicinity of your phone!

Ive bought my fair share of duffers, most have gone back, and a few for free as ebay seller refunded no questions asked (they knew were fake!)

bought some from here tho......

http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWNX:IT

definately genuine, and seriously cheap.... havent looked see if they have more mind you...

ill disect one of the duff ones at some point and post some pictures as comparison.

usually the fakes, the hologram is greener, not so much red and yellow, and they really struggle to show the dots on the sides of the oval logo without turning battery around. genuine ones only require a gentle pan / rotate ..... ie, the battery always faces the same way, you just alter your viewing angle, not direction. and you will see the 1,2,3 and 4 dots on the side.

7 HOURS!!!!! My Nokia doesn't last more than 2 hours outside the house . . .


(while playing mp3's talks on the phone and using the internet - all at the same time of course )

Come on, this time Chinese manufacturers crack the battery-camcoder codes which prevent the usage of non-branded batteries with some camcoders. That requires some control chip. Do you think they are not able to put a simple safety circuit into battery after that?

OK.... so i though sod it, i may as well do it now.....

Check the following out.... in all the pics with 3 batteries, the middle one is FAKE.... so i dismantled it....

Most worringly is the fact it says its 1320mah on the lable.... but inside it says 850mah!!!

most of it was stuck together with sticky foam / glue...

and you can also see what i mean about the hologram colours.

the shape of the face is slightly different....

i also made sure i used 2 genuine batteries from different countries... one came with the N900 itself, and the other from the link i provided earlier.. text does differ between the two genuine ones, so that cant be used to confirm a fake.

hope this helps some peeps out...

mr_bridger, thanks for your pics and for taking the trouble.
Does make me think me cheap Amazon one is genuine though :-)

I confess that my long aversion to the genuine Nokia batteries was formed when they cost like $70 per battery (that was with the N800). Now that they are more reasonably priced, I would probably buy the genuine ones...if I wasn't so used to buying knockoffs.

i have 3 and all of them works great to me the price and there from nokia head over to mobilecityonline.com you cant go wrong
