Introduction
The Einhell 18 V/2.0 Ah lithium-ion battery is an integral part of the Power X-Change modular series. This battery system is designed for compatibility with all Power X-Change series devices. It features an increased capacity for enhanced performance and longevity. The integrated 7-in-1 ABS Active Battery Management System utilizes a microprocessor to continuously monitor critical parameters such as temperature and voltage. High-quality lithium-ion cells are employed to resist self-discharge, and a smooth charging cycle contributes to extended battery life. A three-position LED charge level indicator is included for convenience, and the housing provides high-impact rubber protection. Built-in recessed handles facilitate effortless battery removal.
Safety Information
Always observe the following safety precautions when handling lithium-ion batteries:
- Read all instructions before using the battery.
- Use only the charger specified by the manufacturer for recharging. A charger suitable for one type of battery pack may create a risk of fire when used with another battery pack.
- When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
- Do not use a battery pack or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
- Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 130°C (265°F) may cause explosion.
- Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures outside of the specified range may damage the battery and increase the risk of fire.
- Ensure proper disposal of used batteries according to local regulations.

Maintenance
Cleaning
Keep the battery terminals clean and free from dirt or debris. Use a dry cloth to wipe the battery casing. Do not use water or chemical cleaning agents.
Storage
For optimal battery life, store the battery in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing the battery in a completely discharged state for extended periods. It is recommended to store lithium-ion batteries with a partial charge (around 50%).
Battery Care
- Do not expose the battery to moisture or water.
- Protect the battery from impacts and drops.
- Do not attempt to disassemble or modify the battery pack.
- If the battery becomes excessively hot during use or charging, discontinue use and allow it to cool down before proceeding.
Troubleshooting
Battery Not Charging
- Ensure the charger is properly plugged into a working power outlet.
- Verify that the battery is correctly seated on the charger.
- Check the charger's indicator lights for any error codes or unusual behavior.
- Ensure the battery and charger are within the recommended operating temperature range.
- If the issue persists, try another compatible charger or battery if available to isolate the problem.
Battery Not Powering Tool
- Check the battery's charge level using the LED indicator. Recharge if necessary.
- Ensure the battery is fully and securely inserted into the tool.
- Verify that the tool itself is functioning correctly (e.g., check for blockages, switch issues).
