mAh question

[tlhdoc]

Does a telephone battery with a higher mAh last longer that one with a lower mAh?:confused:
 
Our cordless phone needs a new battery and I want to ge the longest lasting one I can find.

The higher the mAH rating, the longer the battery will last.
 Think of mAH as Amp-hours of the battery on your camper, a battery rated at 220AH will last much longer than one rated at 100AH.
 
  The m=milli= 0.000, therefor 500mAH= 0.500AH

Thanks Charlie, that is what I thought, but I wanted to make sure before I bought one.  I have seen them online from 300 to 1700 mAh.
