This LXHY LA04 battery is a brand-new 11.1 V lithium-ion unit rated at 8.4 Ah and 94 Wh. It uses nine cells in a black housing that measures 10.6 in by 1.6 in by .8 in and weighs 19 ounces. The pack is designed as a direct replacement for the original Lenovo part.

Fits a wide range of ThinkPad T, L, W.

Buyers with a T410s, T410si or any slimline variant not listed should look elsewhere.

Capacity and voltage decide fit

The single specification that determines whether this is the correct part is the 94 Wh capacity at 11.1 V combined with the nine-cell form factor. If the original battery shows the same voltage and watt-hour rating and uses the nine-cell layout, this unit will match the power and physical requirements.

Questions about this item

Does the 11.1V 94Wh 9-cell pack run hot or make noise during all-day use?

The battery has no moving parts and generates no audible noise; normal warmth occurs under load but it stays within the thermal limits of the ThinkPad chassis.

What must my ThinkPad already have for this LA04 battery to fit and charge?

Your laptop must use one of the listed ASM or FRU part numbers — such as 42T4703, 42T4752, 45N1001 or 45N1005 — and the original 11.1 V charging circuit.

Will this 94Wh pack work in my older T410 or T510 that originally shipped with a 6-cell battery?

Yes, the LA04 replaces the 6-cell units for T410, T410i, T510 and T510i; it adds capacity while using the same 11.1 V interface and bay dimensions.
