FAQs

Is this battery compatible with older Hitachi 18V tools?

Yes, HiKOKI 18V slide batteries are generally compatible with existing Hitachi 18V slide-style tools.

How long does it take to charge?

Charge time depends on the specific HiKOKI charger model being used, typically ranging from 30 to 60 minutes for a full charge.

Can I use this in the rain?

While the battery has a protective casing, it is not waterproof. Avoid exposure to heavy rain or moisture to prevent electrical damage.

The four LEDs indicate the remaining charge: four lights mean 100% full, while one light indicates that the battery requires charging soon.

Why are 21,700 cells better than traditional cells?

21,700 cells offer a higher energy density and improved thermal management compared to older, smaller battery cell formats.

Troubleshooting

Battery will not charge on the base

Ensure the charging terminals are free of dust or debris and that the charger is plugged into a functional outlet.

Tool cuts out under load

The battery's overload protection may have triggered. Reduce the pressure on the tool and allow the battery to cool down before resuming.

LED indicator fails to light up

Press the indicator button firmly. If it remains blank, the battery may be completely depleted or experiencing a hardware fault.

Setup, Compatibility & Care

This battery is fully compatible with the extensive range of HiKOKI 18V slide-style cordless tools. Before first use, ensure the battery is fully charged using a compatible HiKOKI lithium-ion charger. To maintain the health of your battery, store it in a cool, dry environment away from direct sunlight and extreme temperatures. Avoid leaving the battery inside the tool when it is stored for long periods to prevent phantom power drain. To clean, use a dry or slightly damp cloth; never immerse the battery in water or use harsh chemicals that may degrade the rubberized casing. Periodically inspect the terminals for debris to ensure a clean electrical connection.
