Battery Replacement for the ADA MP-1.
Replace batteries easily in the future. Solder the red wire to the hole where the positive pin of the original battery was and the black to the negative. Instead of unsoldering/resoldering a new battery cell each time the batteries need to be replaced, you can simply pop out the old commonly available CR2032 coin cell and pop in a new one. Each holder comes with a velcro dot for easy mounting. The battery leads can be easily disconnected via the 2-pin connector for even easier battery changes. A fresh CR2032 coin cell is included and comes pre-installed.
