sorry think i mean mAh

mAh = milliAmperehour. the power consumption rating of an electronic device, or the storage capability of a device like an NiMH or Nicad rechargeable battery.


The higher the figure, the more charge the battery will hold (i.e. it'll last longer between charges).

NiMH = Nickel metalhydride


NiCad = Nickel Cadmium



NiMH are generally better as I believe that they do not have a "memory". i.e they can remain partially charged/recharged for long periods without reducing their original storage capacity (mAH).

Just remember that what you think is a 1.5 volt battery is only 1.2 volts if it's rechargeable, so some pieces of equipment won't work properly with rechargeables no matter what the amperage is.
