Hi There
I have been extensivly testing the BL-5F 1450 mAh extended batteries from Panda for just over a month now on both my N96 on t-mobile used for business and my wifes N96 phone on vodafone used for multimedia.
The batteries are giving an extra 1 1/2 to 2 days life in standard use and with no problems at all. They also fit inside the standard cover with no modification at all.
I expect that the battery re-charges may be less then an original battery, but even if the batteries only last half the life span of an original nokia, at the price of �7.50 one can buy 3 for the price of an original and change them if and when they start to fade after 6 months or so.
I have also checked the factory in China, they also seem to produce batteries for a large number of other handset manufactures. I hope that this may help any user who unhappy with the standard battery or cannot bother trying to get a BL-6F in to the battery housing.
Please note that I have no connection with Panda products!
Ciao
