Battery Pack
BATTERY TYPE
The DCT410, DCT411 and DCT412 operate on
10.8 volt battery packs.
Storage Recommendations
1. The best storage place is one that is cool and
dry, away from direct sunlight and excess heat
or cold. For optimum battery performance and
life, store battery packs at room temperature
when not in use.
2. For long storage, it is recommended to store a
fully charged battery pack in a cool, dry place
out of the charger for optimal results.
NOTE: Battery packs should not be stored
completely depleted of charge. The battery pack will
need to be recharged before use.
