Description

Replacement Battery Newell NL3257 for Xiaomi Roborock (compatible MIS56T6VX) is a direct-fit rechargeable battery pack designed to restore or extend the runtime of compatible Roborock robotic vacuum cleaners. The Newell NL3257 is intended as a service part to replace an aged or degraded factory battery, allowing the robot to complete cleaning cycles with improved runtime compared to a worn cell.

Advantages

The Newell NL3257 replacement battery provides stable power delivery and is designed to match the physical dimensions and electrical characteristics required by supported Xiaomi Roborock units. It enables straightforward battery swapping to recover lost runtime without replacing the entire robot. The battery is produced to meet general safety and performance expectations for consumer rechargeable packs and can help maintain consistent cleaning performance when installed correctly.

Suitable for

Routine maintenance and battery replacement of compatible Xiaomi Roborock robotic vacuum cleaners
Restoring suction runtime and cleaning area coverage after original battery capacity has decreased
Service or repair tasks where the robot requires a new battery pack to function normally

Key specifications

How to use

Before installation, power off the robot and consult the robot manufacturer’s manual to verify compatibility and any model-specific disassembly instructions.
