6-Cell 48Wh Replacement Battery

This 6-cell lithium-ion pack delivers 48Wh at 10.8V for Lenovo ThinkPad X240 through X270 and T440 through T470P models. It replaces part numbers such as 45N1125, 45N1128 and 0C52861. The unit is new and includes overcharge, overdischarge, over-temperature and short-circuit protection. It is not for owners of 9-cell 94Wh systems or laptops outside the listed series.

Drop-in fit for existing chassis

The battery slides into the standard bay without adapters, freeing the AC adapter for travel use. Built-in protection circuits guard the pack and the notebook during daily charge cycles. No extra cabling or firmware updates are required. Buyers needing hot-swap capability or a second battery for continuous uptime should look elsewhere.

Rated for 500 recharge cycles

Under sustained daily charging the pack is rated for up to 500 full cycles before capacity drops below useful levels. Protection circuits throttle current when cell temperature rises, preserving long-term health. The 60-day refund and 12-month replacement window covers early failures. Users expecting multi-year runtime without degradation will find the chemistry limits normal.
