Compatible HP EliteBook and ZBook models

This 3-cell lithium-ion battery fits HP EliteBook 735 G5, 745 G5, 830 G5, 840 G5 and ZBook 14u G5 laptops. It supplies 50 Wh at 4330 mAh for mobile professionals who need a direct replacement. Buyers with other HP series or non-HP notebooks cannot use this pack.

Sustained discharge and cycle life

The lithium-ion chemistry delivers steady output during long work sessions away from mains power. Capacity remains stable across repeated charge cycles under normal office loads. Extreme temperatures or continuous heavy draw will reduce effective runtime faster than light use.

Straightforward swap with model verification

Installation requires removing the bottom case and disconnecting the old pack, then fitting this unit using the original connectors. The most common issue is ordering the wrong part number for a similar-looking chassis. Always match the exact model list before purchase.

Questions about this item

Does the 3-cell 50Wh lithium-ion pack run hot or draw extra power during a full workday?

The 50Wh capacity and 3-cell design match the original HP specification, so heat and power draw stay within the laptop's normal thermal envelope.

What must I already own for this 933321-855-TM battery to work?

You need one of the listed HP models — EliteBook 735 G5, 745 G5, 830 G5, 840 G5 or ZBook 14u G5 — because the connector and firmware are specific to those chassis.

Will this 4330mAh replacement behave the same as the original battery in my EliteBook 840 G5?

Yes, the 50Wh rating and lithium-ion chemistry are identical to the factory pack, so charge reporting, runtime and calibration work without any BIOS update.
