To obtain the best life from the battery
1. Never allow the battery to completely discharge before recharging. The battery
pack should be placed on the charger whenever the battery pack is noticeably
running down or the tool no longer performs a task it previously performed.
2. Avoid conducting short charges. Make sure that the battery is fully charged every
time by allowing the charger to complete its full charging cycle.
3. Avoid allowing lose items like screws or nails etc. to be stored with battery packs
as these or similar items can short battery packs and cause a fire or explosion.
4. Always unplug the charger when not in use and store in a dry secure place.
5. Avoid charging or storing your battery in temperatures below 32°F and above
113°F.
6. Cool down hot battery pack from a just-operated tool for approximately 30
minutes before attempting to recharge.
