What this battery replaces

This NShi 44++ 9-cell lithium polymer battery replaces Lenovo part numbers 0A36307, 0A36282, 0A36283, 42T4875, 42T4861, 42T4873, 42T4867, 42T4902, 42Y494042T4863 and 42Y4864. It is built for ThinkPad X220, X220i and X230 notebooks. Buyers who need a different form factor or a higher cell count should look elsewhere.

Fitting it into your laptop

The pack slots into the standard battery bay on the supported models with no extra brackets or cabling required. It restores full mobile operation for machines that currently run only on AC power. Systems outside the X220 and X230 series cannot accept this pack.

Behaviour under sustained load

The 9-cell layout delivers extended run time compared with lower-capacity packs during long work sessions away from a socket. Lithium polymer chemistry maintains stable voltage output as the charge depletes. Runtime will vary with screen brightness, processor load and wireless activity.

Does the lithium polymer 44++ battery run hot or make noise during all-day use?

The battery has no moving parts and operates silently; lithium polymer cells generate minimal heat under normal charging and discharging cycles.
