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(s) (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 only in dry conditions and at an
ambient temperature of 50°F - 104°F (10°C - 40°C).
5. Do not keep the battery charger in places where the
temperature is liable to reach over 104°F (40°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 50°F - 104°F
(10°C - 40°C). Store your lithium-ion battery pack(s) in a
cool, dry place at a temperature of 50°F - 68°F (10°C -
20°C). Protect the battery pack(s), 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(s) 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.
