Compatible Replacement for HP 612 Tablet

The PowerWarehouse KK04XL is a new 4-cell lithium-ion battery built to fit the HP 612 Tablet and the HP Pro X2 612 G1 Tablet. It replaces OEM part numbers KK04XL and 753703-005. This unit is intended for owners of those specific tablets who need a direct swap for a depleted original pack. Buyers with other HP models or different tablet lines cannot use this battery.

Voltage and Capacity Limits

The pack delivers 7.4 V and 3820 mAh, which fixes the energy available for each charge cycle. Runtime will vary with screen brightness, wireless activity and workload, so heavy use will drain the cell faster than light browsing. The chemistry is rated for typical lithium-ion cycle life; capacity will gradually decline after repeated full discharges. No higher-capacity alternative is offered in this form factor.

Four-Cell Build and Daily Handling

A four-cell lithium-ion construction keeps the brick slim enough to sit inside the tablet chassis without adding bulk. The shape matches the original cavity, so the tablet rests flat on a desk and the latch engages without force. Cells are enclosed in a hard shell that resists flex during normal carry. Installers should align the connector carefully; the keyed plug prevents reverse insertion but still requires gentle pressure.

Questions about this item

Which capacity should I pick for my HP 612 Tablet?

This pack is rated 3820 mAh at 7.4 V and is the only capacity offered for the KK04XL replacement.

What does the 3820 mAh rating mean in daily use?

It indicates the charge the 4 cell lithium-ion unit can store, giving run-time comparable to the original HP 753703-005 battery.

What connector standard does the battery use and what does it limit?

It uses the proprietary HP 612 Tablet interface, so it fits only that model and the Pro X2 612 G1.
