New Lithium-Ion Battery - Hitachi C 18DL Technical Data And Service Manual

4-2. New Lithium-ion Battery

The Type EBM 1830 lithium-ion battery is equipped with the overdischarge protection circuit, overload protection
circuit, and voltage monitoring circuit for each cell to prevent reduction of the battery life due to overdischarge
(overuse) or overcharge (excessive charging) of the battery.
The number of charging/discharging is about 1,500.
Type EBM 1830 lithium-ion battery is equipped with a protective function that automatically stops output to extend
the battery life. The motor may stop automatically in either of the following case
depressed continuously during operation. This is because the protective function is activated. The battery is not
faulty.
The motor may stop automatically when the remaining battery level is low (when the battery voltage is
1
decreased to about 12 V (Type EBM 1830)). Charge the battery immediately in such case.
The motor may stop if the Model C 18DL is overloaded. In such case, release the switch and eliminate the
2
cause of the overload problem. Then the Model C 18DL is operable.
The Type BCL 1815 lithium-ion battery (optional accessory) is intended for light-duty work. Do not use the Type
BCL 1815 lithium-ion battery with the Model C 18DL. Otherwise, the battery life may be shortened extremely.
Please instruct the customers on the above precautions.
