Vacuum Battery Replacement for Lefant M501/M501B Robot Vacuum Cleaner

Upgraded 2800mAh Battery to Replace your Lefant M501B Robot Vacuum Cleaner

The Lefant M501B Robot Vacuum Cleaner can now be upgraded with a powerful 2800mAh battery, providing you with longer working time and the ability to clean larger areas at once.

Battery Features:

1. The new battery may require several charges before it stabilizes. Don't worry, this is normal. The machine may stop charging the battery when it's half charged (sometimes more, sometimes less) due to voltage and current instability. If this happens, simply remove the battery and recharge it again.

2. During normal operation, the battery must be recharged or shut down when it reaches 3% discharge. Discharging the battery to 0% will damage it and shorten its lifespan.

3. Avoid dropping, heating, and short-circuiting the battery. Do not use it in environments with extreme temperatures, either high or low.
