Compatible replacement battery

This lithium-ion pack replaces the original battery in Midea M4, NEO 820P and NEO 830P robot vacuum cleaners. It delivers 3400mAh at 14.4V for 48.96Wh of capacity. The 69.00 x 37.60 x 37.30mm form factor matches the factory unit exactly.

Fully decoded chip and protection

A new fully decoded chip works just like the original so the vacuum recognises the pack without errors. Built-in overcharge, over-discharge, over-voltage and short-circuit protection helps preserve cell life. Shock-absorbing foam in the package guards the battery during transport.

Lithium-ion chemistry limits

Lithium-ion cells degrade faster if stored above 60°C or left deeply discharged for long periods. The pack reaches its best performance after two or three full charge and discharge cycles. Using a low-quality third-party charger can shorten the overall service life.
