12-cell replacement battery for HP EliteBook

This new lithium-ion pack is built for HP EliteBook 8460p 8460w 8470p 8470w 8560p 8570p and ProBook 6360b 6460b 6465b 6470b 6475b 6560b 6565b 6570b models. It suits owners who need a direct swap for an ageing original battery. Buyers whose laptops fall outside this compatibility list cannot use it.

7800 mAh capacity at 11.1 V

The single specification that decides fit is the 7800 mAh capacity delivered at 11.1 V across 12 cells. This matches the electrical profile required by the supported notebooks. A different voltage or cell count will not work in these machines.

Slide-in installation with built-in safety circuits

The battery slides into the standard bay without tools and locks with the existing latch. Integrated protection covers overcharge over-discharge thermal runaway and cell imbalance shut-off. The only common issue is forgetting to charge the pack fully before first use which can trigger the protection circuit.

Questions about this item

What does the 7800 mAh capacity mean for daily runtime on an EliteBook 8470p?

The 7800 mAh lithium-ion pack supplies more stored charge than standard batteries, so the EliteBook 8470p runs longer between charges under the same workload.

How does the 11.1 V rating affect compatibility with a ProBook 6470b?

The 11.1 V output matches the voltage the ProBook 6470b expects, so the battery connects directly without an adapter or voltage conversion.

Will the 12-cell form factor fit inside a ProBook 6560b chassis?

This 12-cell pack is built to the same physical outline as the original battery for the ProBook 6560b, so it seats in the standard bay without modification.
