9. Do not use batteries that have been exposed to heat
during the charging process, as the battery cells may have
suffered dangerous damage.
10.
Do not use batteries that have suffered deformation during
the charging process or those that exhibit other atypical
symptoms (gassing, hissing, cracking, etc.).
11. Never fully discharge the battery pack (maximum
recommended depth of discharge is 80%). A complete
discharge of the battery pack will lead to premature
degradation of the battery cells.
Protection from environmental influences
1. Protect the battery charger from moisture and rain.
Moisture and rain can cause dangerous cell damage.
2. Do not use the appliance or the battery charger near
vapors and flammable liquids.
3. Use the battery charger and the appliance only in dry
conditions and at an ambient temperature of 41ºF – 105°F
(5°C – 40.5°C). Particularly, do not leave the battery or
charger in a hot car.
5. 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.
6. Store the charger and your appliance 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 appliance from humidity and direct
sunlight. Only place fully charged batteries in storage
(charged to at least 40%).
7.
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.
8. 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 terminals.
