I am repairing a battery pack that likely has 1200mAh SubC NiCD batteries in it. Can I mix a 1200mAh and 2400mAh battery in the same pack wired in a series circuit?
Yes you can but now you have a 1200mAh systemMake sure you mean series because this answer is based on that.if its a parallel system ,,,that is,, where the output voltage is no greater than any one of the batteries by itself,, then your good to go.and all you have done is drop the time that it will take to discharge the whole systemMost battery packs for drills have a battery pack with cells all alike for a reason .the least charged cell will determine the life.from the E.
very confusing factor. search at yahoo or google. that will could actually help!
NO The lower capacity battery will go flat before the higher capacity battery. The higher capacity battery will then attempt to partially charge the lower capacity battery which will cause it to heat up. The charging of the lower capacity battery won't be properly regulated and this could cause a fire.
