Banshee 19.2V 2000mAh Power Tool Battery

Purchased the 19.2 Volt drill in 2007. The batteries that came with it had to be charged before use. They would last 10-15 minutes and die. Installed new battery (number 1, after charging) on April 26, 2022. Have reinforce old cabinet, built new 8 foot storage shelf, disassembled and reassembled old 8 foot storage. Used most of a new box of wood screws (1 lb./about 100). Battery number 1 still on the drill May 3, 2022. Will install battery number 2 when number 1 slows down. This way I will use most of the juice in one before using the other. This is to avoid recharging the battery just to "TOP OFF". Deep cycle each battery trying to avoid "MEMORY", if it exists. So, my 15 year old 19.2 volt drill runs like new!!! Not much else I can say. Maybe good price and delivered when promised. I would give more stars for the total experience. Thank So Much, Ray
