Service Life of Rechargeable Battery Cartridge:
Lithium-ion batteries used in the battery cartridge will gradually deteriorate during
the repeated cycles of charging and discharging due to its properties, even under
normal use. When the battery run time becomes shortened due to its deterioration
even if it has been charged for the specified hours, replace the battery cartridge with
a new one. Generally, it is necessary to replace the battery cartridge after it has
undergone approx. 300 cycles of charging and discharging operation.
