The battery operates at 10.8 V with a rated capacity of 5.2 Ah and 57 Wh, matching the figures printed on the factory cells. Confirm that your laptop requires exactly this voltage before fitting the pack.

Steady output over long sessions

Lithium-polymer chemistry maintains a stable voltage curve during extended use, so the laptop runs at consistent performance without the sharp drops seen in aged cells. High recycle life means the pack retains useful capacity after many charge cycles. Buyers needing a slimmer pack for T410s, T420s, T430s, T440, T450, T510s, T520s, T530s, W500, P series or X series models cannot use this battery.

Questions about this item

How long will the 57 Wh capacity actually run my ThinkPad T430?

The 57 Wh rating means the pack stores 57 watt-hours; real runtime depends on your model's power draw, screen brightness and workload, but it matches the original 10.8 V 5.2 Ah specification for listed ThinkPads.

Does the 10.8 V output work with the original charging circuit in a T420?

Yes, 10.8 V is the standard voltage for the listed ThinkPad L, T and W series, so the battery connects to the same charging controller without modification.

Will this pack fit the battery bay on a ThinkPad T430s?

No — the supplier explicitly states it does not work in T430s or any slim S-series models; it fits only the standard L410–L430, T410–T430 and W510–W530 chassis.
