Product Information
Full details
The Kielder 18V 4.0Ah battery is designed for Kielder TYPE18 tool users seeking extended runtimes and reliable power. Its key benefit is a significant increase in working time compared to smaller capacity batteries, allowing for longer periods of use between charges. A potential caveat is its weight, which is higher than smaller capacity options, though this is offset by its increased power output. This battery features high-quality Li-ion cells, optimized power delivery through synced tool electronics, and an LED charge indicator for convenience.

Troubleshooting
Battery not powering the tool
Ensure the battery is correctly and fully seated in the tool. Check the LED charge indicator; if no lights illuminate, the battery may be depleted or faulty. Try charging the battery fully.
LED indicator not working
This could indicate a fault with the indicator. Ensure the battery is charged and try it in a tool. If it still does not power the tool, contact customer support.
Reduced runtime despite full charge
Check for excessive heat. If the battery feels unusually hot, allow it to cool down. Ensure the tool's operation is not obstructed. If problems persist after several cycles, contact customer support.
Battery won't charge
Ensure the charger is plugged in and functioning correctly. Clean the charger and battery contacts with a dry cloth. Try a different compatible Kielder TYPE18 battery in the charger to test the charger. If the charger works with another battery, the issue is likely with this battery.
