The AH (Amp Hour) Rating is the storage (or fuel) of the battery, the higher it is the longer the battery lasts between charges, bit like petrol in your car so a higher or lower one makes no different to the performance, just the length of time you can use the tool for. Compatable with original chargers and OEM equipment. Colour:Silver Dimension: mm
