9. Charging batteries at a temperature below 41°F (5°C) will
cause chemical damage to the cells and may cause a fire.
10. Do not use batteries that have been exposed to heat
during the charging process, as the battery cells may have
suffered dangerous damage.
11. Do not use batteries that have suffered curvature or
deformation during the charging process or those that
exhibit other atypical symptoms (gassing, hissing,
cracking, etc.).
12. Never fully discharge the battery pack (maximum
recommended depth of discharge is 80%). A complete
discharge of the battery pack will lead to premature aging
of the battery cells.
Protection from environmental influences
1. Wear suitable work clothes. Wear safety goggles.
2. Protect your cordless tool and the battery charger from
moisture and rain. Moisture and rain can cause dangerous
cell damage.
3. Do not use the cordless tool or the battery charger near
vapors and flammable liquids.
4. Use the battery charger and cordless tools only in dry
conditions and at an ambient temperature of 41ºF – 105°F
(5°C – 40.5°C).
5. Do not keep the battery charger in places where the
temperature is liable to reach over 105°F (40.5°C). In
particular, do not leave the battery charger in a car that is
parked in the sunshine.
6. Protect batteries from overheating. Overloads,
overcharging and exposure to direct sunlight will result
in overheating and cell damage. Never charge or work
with batteries that have been overheated – replace them
immediately, if possible.
7. Store the charger and your cordless tool only in dry
locations with an ambient temperature of 41ºF – 105°F
(5°C – 40.5°C). Store your lithium-ion battery pack in a
cool, dry place at a temperature of 77°F (25°C). Protect
the battery pack, charger and cordless tool from humidity
and direct sunlight. Only place fully charged batteries in
storage (charged to at least 40%).
8. Prevent the lithium-ion battery pack from freezing. Battery
packs that were stored below 32°F (0°C) for more than
60 minutes must be discarded.
9. When handling batteries, be wary of electrostatic charge.
Electrostatic discharges can damage the electronic
protection system and the battery cells. Avoid electrostatic
charging and never touch the battery poles.
