3.Regular Use - Avoid leaving the battery KNB-57L idle for extended periods. It is advisable to use the battery at least once every two to three weeks. If the battery has been unused for a long time, follow the initial break-in procedure as recommended for new batteries.

4.Calibration - If the battery indicator shows 76% or less during use, fully charge it, then fully discharge it, and finally recharge it completely to calibrate the battery level accuracy.

5.Usage on Fixed Power - Consider removing the battery from the laptop when using a fixed power source for extended periods to reduce unnecessary charging cycles.

6.Short-Circuit Prevention - Do not short-circuit the battery, as this can cause serious damage and compromise safety.

By following these practices, you can help maintain the performance and extend the life of your Kenwood KNB-57L Battery.
