Nokia N75

I've done a little research on the N75 battery issue.

For those who are saying to use the BL-4B battery in the N75 - you are plain wrong. There are many sites out there who are saying it is the correct battery for the N75, but they are wrong. The BL-4B is only rated at 700mAh, while the correct battery is rated at 760mAh. (These are the NOKIA ratings listed for the batteries themselves. Beware, there are incorrect specifications listed everywhere on the net). The BL-4B will fit, and yes it will power the phone - but it has less capacity than the BL-5B.

The BL-5B IS the correct battery for the N75. This gets confusing as Nokia's own web site shows TWO BL-5B batteries (one with the BL-5BT label, the other simply as BL-5B). However, both are rated at 760mAh.

To further confuse the issue, a number of web sites are selling "Equivalent" batteries for the N75 which are only listed at 500mAH. Good luck with those batteries.

This phone needs all the capacity it can get. Putting a 700mAh battery in this phone when a 760mAh battery is recommended is just not good (nearly 10% less capacity).

Personally, I think Nokia is working on a greater capacity extended battery.

If you want to be bold, there are already folks advertising 820mAh and even a 1000mAh BL-5B equivalent (just search for N80 battery - as the N80 also takes the BL-5B).
