Direct replacement for HP business notebooks

This 6-cell lithium-ion battery delivers 5200 mAh at 11.1 V and fits the HP Compaq 6530b, 6535b, 6730b and 6735b series plus the EliteBook 6930p, 8440p and 8440w and ProBook 6440b, 6445b, 6450b, 6540b, 6545b, 6550b and 6555b models. It matches OEM part numbers HSTNN-IB68, HSTNN-IB69, HSTNN-CB69 and HSTNN-UB68. Built-in overcurrent, overcharge, overdischarge, over-temperature and short-circuit protection supports up to 500 recharge cycles.

Replaces worn or failed original packs

Swap this unit in when the factory battery no longer holds a useful charge or shows swelling. The 5200 mAh capacity restores the runtime the laptop had when new, so the upgrade is worth it whenever the original pack falls below that level. It is not suited for users who need a higher-capacity extended pack or a second battery for hot-swap operation.

Simple slide-in installation

The pack clicks into the standard battery bay without tools; most owners complete the swap in under a minute. Align the contacts, press until the latch engages, then charge fully before first use. The only common issue is forgetting to update the BIOS on older EliteBook or ProBook units, which can prevent the new pack from reporting capacity correctly.

Questions about this item

Does the 6-cell 5200mAh battery match the HSTNN-IB68 or HSTNN-UB68 form factor for my HP 6530b?

Yes, this 11.1V Li-ion pack is built to the HSTNN-IB68, HSTNN-IB69, HSTNN-CB69 and HSTNN-UB68 dimensions used by the 6530b, 6535b, 6730b and 6735b series.

Which way do the three locking tabs engage when I slide the pack into the ProBook 6440b bay?

Insert the battery with the label facing up, push until the two side latches click and the centre tab snaps into the recessed slot; the common mistake is stopping at the first click without seating the centre tab.

After roughly 500 recharge cycles the runtime drops off — what replacement spec should I search for?

Look for a 6-cell 5200mAh 11.1V Li-ion unit that lists the same HSTNN-IB68, HSTNN-IB69, HSTNN-CB69 or HSTNN-UB68 part numbers for the 6530b, 6440b, 6445b, 6450b, 6540b, 6545b, 6550b, 6555b, 6730b, 6735b, 6930p, 8440p or 8440w models.
