Battery

You could use other rechargeable batteries sold in a market, but the unit is not guaranteed to work 
properly.

The battery strength may not be indicated correctly if the battery is disconnected and connected again, 
even after it is fully charged. In that case, by recharging the battery as mentioned in the Operating  
Instructions, you will get a correct indication of the battery strength.
