The big question is: Is it a rechargeable battery?
100mAh sounds awfully low though, so I'm guessing no.
Is it a toy? :P

Capacity is a measure of how much charge the battery has.
100mAh will last for 100 hours if the synth drains 1mA from it, 1000 hours
if it drains 0.1mA from it, and so on... (in theory)
So, bigger is better as it will last longer.
