13. STORAGE OF LITHIUM-ION BATTERIES
WARNING
● If a conductive object gets into the terminal of the lithium-ion battery,
the battery may be shorted, causing heat generation, smoke, or ignition.
Therefore, be sure to obey the following when storing.
○ Do not put conductive chips, nails, wires, copper wires, or other wires in
the storage case.
○ To prevent shorting from occurring, load the battery in the wrench body
or insert the battery cover securely for storing until the ventilator is not
visible.
CAUTION
● Fully charge the lithium-ion battery before storing it.
■ If the storage battery is stored for a long time (3 months or more) with
low remaining capacity, the storage battery may deteriorate, the usage
time may be significantly shortened, or the battery may not be charged.
Even if the storage battery’s usage time is significantly reduced, it may
be restored by repeating charging and use 2 to 5 times. If the usage
time is extremely short even after repeated charging and use, it may
indicate the end of the battery life, and we recommend you purchase a
new battery.
