As this is not that difficult mod, I'm not going to try to make this article overly detailed. I just wanted to document this little "mod" that I made for my Nokia 6600 cellphone and mainly to its battery. 6600 uses the BL-5C battery out from the box. It has capacity of 850 mAh. As 6600 is not just a phone but can run symbian software, it tends to drain the battery relatively fast. I was getting it to run around 3-4 days before it would start to let me know that I should recharge the batteries.

3-4 days is a quite good total for many users but my Sony Ericsson P800 was getting me close to a week so I decided to see if there was something that I could do to improve the battery life. I came to conclusion that I had two choices. Either stop playing games and testing software on the phone or replace the battery with something more powerfull. I chose the latter option and decided to look for replacement.

As Nokia doesn't officially support other than BL-5C in their 6600 mobile phone, I had to look for alternatives from their other models. I found out that the new N-Gage QD uses almost identical battery in terms of size; BL-6C. It also offered battery capacity of 1070 mAh with only 4 gram weight increase so I got interested about it. 26% increase in milliampere hours should give a nice real life performance boost to operation time.

As BL-5C is used in many other models than 6600, I believe that this mod/replacement is usable on these other cellphones too. 1100, 2300, 3100, 3650, 3660, 6230, 6600, 6630, 6820, 7600, 7610 and N-Gage use BL-5C so replacing it should not be that difficult task. Naturally I haven't tried this mod on all of these phones so there may be more strict dimension requirements on some models than in 6600 but at least you know that they are compatible electrically.

Interesting article, I'm curious how well this would work with the 6630 - there seems to be some extra space behind the battery, if you move the phone back and forwards you can hear the battery rock back and forth, so I wonder if this bigger battery would fit straight in? Perhaps a bit optimistic, but it would be nice!
