Check voltage and model number before ordering

Your laptop must accept a 10.8V or 11.1V battery; other voltages are not supported. Confirm the exact model number printed on your current battery or chassis matches the compatible list above. The battery is brand new and contains no memory effect, so it arrives ready for the initial conditioning cycle. Physical dimensions and connector layout follow the original design for direct fit.

Sustained runtime from high-capacity cells

The 7800mAh rating delivers longer operation between charges compared to standard lower-capacity packs. Premium A-grade cells and a protection circuit board maintain stable output during extended workloads. The lithium-ion chemistry avoids capacity loss from partial discharge cycles over time. Fully charge and discharge three times initially to reach maximum rated capacity.

Questions about this item

Does the 9-cell 7800mAh battery ship with any cables or chargers, or is it just the battery itself?

The package contains the replacement battery only; no cables, chargers or additional accessories are included.

My laptop originally used a 10.8 V pack — will the 11.1 V rating on this 9-cell unit cause any issues?

The battery is designed to fit devices rated for either 10.8 V or 11.1 V, so it will work with your original voltage specification.

What runtime improvement can I expect from the 7800 mAh capacity compared with a standard 6-cell pack?

The 7800 mAh, 9-cell design stores substantially more energy than a typical 6-cell battery, delivering longer run time between charges.
