Dr. Battery MPL10227P-09 6-cell 4400 mAh 10.8 V laptop battery

Replacement battery for Lenovo Essential and IdeaPad

The Dr. Battery MPL10227P-09 is a new 6-cell lithium-ion unit rated at 10.8 V and 4400 mAh. It matches the original part numbers including 121001096, 57Y6454 and 57Y6455. Compatible models cover Lenovo Essential B470, B570, B575e, G460, G560, G570, G780, V470 and V570 alongside IdeaPad Z370, Z560, Z565, Z570, Z570A and Z575.

Upgrade from a depleted or lower-capacity pack

This 48 Wh battery replaces the factory cell when run-time has dropped or the original 6-cell pack has aged. The jump is worth it when the laptop still meets daily workloads but cannot hold a charge through a typical work session. Buyers who need longer unplugged time than 4400 mAh provides should look for a higher-capacity alternative.

Fits the existing battery bay without modification

The pack uses the standard 10.8 V interface and physical layout for the listed models, so no adapter or chassis change is required. A built-in smart control chip manages charging, short-circuit, overheat and overload protection. The design frees the user from carrying a power brick for short trips while keeping the original form factor.
