9.4.8 Handling Batteries
This battery pack uses two primary lithium/
thionyl chloride batteries. Each battery contains
approximately 5 grams of lithium, for a total of 10
grams in each pack. Under normal conditions,
the battery materials are self-contained and are
not reactive as long as the batteries and the pack
integrity are maintained. Care should be taken to
prevent thermal, electrical or mechanical damage.
Protect the electrode of the battery pack to avoid
rapid electrical discharge. Discharged a battery may
lead to fluid leakage and excessive heat. Batteries
should be stored in a clean and dry area. For
maximum battery life, storage temperature should
not exceed 30°C.
WARNING
Handling the battery pack
The following precautions must be observed
in order to safely and effectively use a battery
pack. Improper use may lead to fluid leakage,
excessive heat, ignition, or explosion.
• Never charge it.
• Do not short-circuit it.
• Do not disassemble, transform, or modify it.
• Do not heat it or throw it into a fire.
• Do not soak it in fresh water or seawater.
CAUTION
Observe the following precautions for the safe
disposal of batteries.
• Do not incinerate the battery, and do not
expose it to a high temperature of 100°C
or more. This may lead to fluid leakage or
explosion.
• Dispose of the battery according to laws and
regulations.
Use the following dedicated parts for the battery
pack and batteries.
