> Every new model used a different battery. In the 90s when the phones were rapidly evolving and the batteries where huge and often incorporated into the exterior design of the phone. My first Nokia ~1997 was the size of a large TV remote, the second was the size of a king size snickers, the third was smaller than a regular size snickers. I had the Nokia 8290, and 6590 which were about 2 years apart and they used the same battery. They really didn't have that many batteries across their line after 1999: http://pinoutguide.com/CellularPhones-A-N/nokia_blb_battery_pinout.shtml http://pinoutguide.com/CellularPhones-A-N/nokia_blb_battery_...
