Danger of Lithium batteries
Lithium batteries have high energy density and provide
high performance in their application Therefore, all safety
instructions must be followed carefully when using, charging
and storing lithium batteries. Due to their performance, all
lithium batteries are potentially hazardous when damaged
or used improperly, and may pose a serious RISK OF FIRE,
for example, there is a risk during charging in these cases:
- Battery was fully discharged and was not recharged in
a short time. - Lithium batteries should be recharged
within 24 hours after use, especially if they have been
completely or nearly flat.
- Charging is performed at temperatures below 4 °C.
- Charging below 4 °C causes a chemical reaction in
the battery cells which can cause permanent damage,
explosion or fire during charging
- Battery was in contact with liquid. (Salt water is
especially risky.)
- Exposure to liquids can cause internal corrosion, cell
damage or internal battery management system (BMS).
BMS protects the battery from overcharging, deep
discharge, or unbalanced cell charging. Therefore, a cell
or BMS failure may present a risk of fire during charging
- Operating or charging a battery that has been damaged
by dropping or shipping.
- If a crack or any mechanical damage occurs on the
battery cover, the battery must not be used or charged.
- Use of a charger other than the original one (supplied
with the device)
- Each battery chargers charges specific voltage, current
and has some other specific parameters to manage
the charging of the battery. These parameters will vary
significantly when using a different charger (for example,
for different types of batteries - SLA, NiCd, NiMH, etc.).
PRODUCT SAFETY INFORMATION
Therefore, never use any charger other than the one
supplied with the device. Do not use for charging dry
cells that are commonly used in household appliances.
These batteries may break and cause personal injury
and damage to property.
- NEVER LEAVE THE DEVICE ON DIRECT SUN OR IN
PLACES WITH HIGH TEMPERATURE (temperature
above 50 °C / e.g. behind car window in summer)!!!
- Temperature higher than the critical limit can result in
overheating of lithium batteries, their explosion and
subsequent flare-up. This warning applies generally to
ALL devices in which lithium batteries are used.
Service
- Do not attempt to repair the device yourself. Any work
not listed in this manual MAY BE PERFORMED ONLY BY
AUTHORIZED SERVICE CENTRES.
- Have your power tool serviced by a qualified repair
person using only identical replacement part s. This will
ensure that the safety of the power tool is maintained.
