FAQs

Q: How do I ensure compatibility with my power tools?

A: Please verify that your tool model or the original battery part number is listed in our compatibility table. Additionally, ensure that the voltage, connector interface, and physical dimensions match your original MAK-9120 battery.

Q: Is a 12-hour initial charge necessary for this nickel battery?

A: Yes. To optimize cell chemistry, new nickel-based batteries require a "forming" process. We recommend a continuous 12-hour initial charge, followed by 2-3 complete charge/discharge cycles to achieve maximum runtime and peak performance.

Q: How do I manage the "Memory Effect" of nickel cells?

A: To maintain maximum capacity, utilize the battery until a significant drop in tool performance is observed before recharging. Periodically performing a full discharge-recharge cycle helps calibrate the cells and prevents capacity loss over time.

Q: How to care for my power tool battery and extend its life?

A: 

1. Cool Down: Never charge a battery that is still hot from use. Let it cool for 15-30 minutes before placing it on the charger.

2. Proper Storage: If the battery will not be used for a long time, do not store it empty. Charge it fully and store it in a dry, cool environment.

3. Regular Use: Nickel batteries suffer from high self-discharge; we recommend using and charging the battery at least once every 2-3 weeks to keep the cells active.
