Maintenance - Replacing Batteries

For battery replacement use a Philips screwdriver to open the case. 

Replace the batteries making sure to install them by the right direction.

Important! Always use a new set of batteries. Do not mix used and new batteries in the charger! This will effect the power output. 

Close the case with the screwdriver.

Note: Never use rechargeable batteries!

A new set of batteries should last for about 50 chargers.
