4. Removing the Battery: Press the release button (usually red, as seen in Figure 3.1) and slide the battery out of the tool.

5. Operating the Battery

Once installed, the battery powers the connected tool. Observe the following during operation:

• Power Indicator: Periodically check the 4-LED indicator (Figure 3.3) to monitor the remaining charge. Recharge the battery when the indicator shows a low level to avoid interruptions.
• Run Time: A fully charged 2.0Ah battery typically provides 20-30 minutes of running time, depending on the tool and application intensity.
• Overload Protection: If the tool draws excessive current, the battery's overload protection may temporarily shut down power to prevent damage. Reduce the load on the tool and restart.
• Overheat Protection: If the battery becomes too hot during prolonged use, the overheat protection will activate. Allow the battery to cool down before resuming operation or charging.
