Replacement Battery for HP ProBook Series

This 11.55 V lithium-ion battery replaces the RE03XL cell used in HP ProBook 430, 440, 445, 450, 455 and ZHAN 66 models across G6 and G7 generations. It delivers 45 Wh capacity and 3750 mAh charge in a black pack measuring 7.25 in by 4.0 in by 0.25 in. The unit ships with instructions and matching installation tools.

Suitable for owners restoring original runtime

The pack fits the listed ProBook and ZHAN 66 chassis without modification and is rated for over one thousand recharge cycles. Buyers whose laptop uses a different part number or who need a higher-capacity option should verify compatibility before ordering.

45 Wh capacity for everyday workloads

The 45 Wh rating supports typical office tasks, web browsing and video playback for several hours on a full charge. Demanding workloads such as sustained gaming, rendering or virtualisation will exhaust the cell more quickly and may require a higher-capacity alternative.
