6-Cell 10.8V 57Wh Replacement Battery

This 6-cell lithium-ion battery delivers 10.8 volts and 57 watt-hours for compatible Lenovo ThinkPad models. It uses A-grade cells rated for 300 to 500 charge cycles and arrives in new condition with a black finish. The pack replaces a wide range of FRU and ASM part numbers including 42T4852 and 57Y4545. It fits systems such as the T430, T530, W530 and L430 series.

Direct OEM Fit With No Extra Components

The battery ships as a standalone unit with no bundled software, adapters or installation tools. Compatibility is determined solely by matching the listed part numbers or supported model names such as ThinkPad T420, T520, W520 and Edge E420. No driver updates or configuration utilities are required for the hardware to function. Buyers who need a charger, external dock or multi-bay caddy must source those separately.

57Wh Capacity Defines Runtime Expectations

The 57 watt-hour rating is the single figure that determines how long the system runs between charges under a given workload. Higher-capacity 9-cell alternatives or extended-life packs are not covered by this part number. Buyers who need more storage for longer unplugged sessions should look for a higher-watt-hour replacement instead.

Questions about this item

How many charge cycles can the 6-cell 10.8V 57Wh battery sustain before capacity drops noticeably?

The cells are rated for 300 to 500 full charge cycles; after that range the pack will hold less charge and run time will shorten.

What is the first limit reached when the battery powers a ThinkPad T430 under continuous load?

The 57 watt-hour capacity sets the runtime ceiling; once that energy is depleted the system must switch to AC power.

Does the 6-cell lithium-ion pack generate noticeable heat or fan noise during all-day use?

The battery itself runs silently and produces only modest warmth; any audible fan noise comes from the laptop's own cooling system.
