Direct replacement for Lenovo notebooks

This Axiom 43R9256-AX battery is built as a direct replacement for compatible Lenovo notebooks. It uses lithium-ion chemistry across eight cells to deliver reliable mobile power. The unit is supplied new and manufactured to match OEM specifications for fit and function. It suits professionals who need dependable runtime away from a wall outlet.

Eight-cell lithium-ion capacity limits

An eight-cell lithium-ion pack provides a fixed energy capacity that defines maximum unplugged runtime. Battery life decreases over charge cycles and varies with workload, screen brightness and power-management settings. Users running sustained heavy loads will see shorter sessions than light productivity work. The chemistry also self-discharges during long storage periods.

Match the 43R9257 part number exactly

The critical specification is compatibility with the Lenovo 43R9257 part number. Installing this battery in a model that requires a different part number will result in a physical or electrical mismatch. Verify the original battery label before purchase to ensure the correct fit. No other specification determines suitability for a given machine.
