8. Never use or charge batteries if you suspect that it has been more than
12 months since the last time they were charged. There is a high probability
that the battery pack has already suffered dangerous damage (exhaustive
discharge).
9. Charging batteries at a temperature below 41
o
F (5
o
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 50
o
F - 104
o
F (10
o
C - 40
o
C).
5. Do not keep the battery charger in places where the temperature is liable to
reach over 105
o
F (40.5
o
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
o
F - 104
o
F (10
o
C - 40
o
C). Store your lithium-ion battery pack
in a cool, dry place at a temperature of 50
o
F - 68
o
F (10
o
C - 20
o
F). Protect the
battery pack, charger and cordless tool from humidity and direct sunlight.
Only place fully charged batteries in storage.
8. Prevent the lithium-ion battery pack from freezing. Battery packs that were
stored below 32
o
F (0
o
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.
