48Wh 11.4V Li-polymer replacement battery

This 48Wh lithium-polymer battery operates at 11.4V and delivers 4000mAh capacity. It is built as a direct replacement for the original WA03XL unit in compatible HP Pavilion X360 convertibles. The black pack matches the factory form factor and voltage specification. Condition is brand new.

Replaces WA03XL, HSTNN-UB7H and two HP part numbers

The battery substitutes for part numbers WA03XL, HSTNN-UB7H, 916367-541 and 916812-855. No separate cables, tools or software are included in the package. Installation relies on the existing laptop chassis and connector layout. Buyers who need a multi-pack or an external charger will not find those items here.

Fits HP Pavilion X360 15-br series models listed

Compatible models include the 15-br001TX, 15-br002TX, 15-br004TX, 15-br005TX and 15-br007TX, all sharing the TPN-W126 platform. The 48Wh capacity restores typical runtime for web browsing and office tasks on these devices. It will not fit other HP series or non-listed 15-br variants. Buyers with different chassis or higher-capacity requirements should verify their part number first.

Questions about this item

When will the 48Wh 11.4V WA03XL battery need replacement?

The 48Wh Li-polymer cell degrades with each charge cycle; expect reduced run-time after several hundred cycles.

What limits the WA03XL 48Wh battery during sustained use?

The 48Wh capacity and 11.4V output set the energy ceiling; long sessions drain the 4000mAh reserve until recharge.

Does the WA03XL 48Wh battery get hot or noisy during all-day use?

The Li-polymer pack has no moving parts so it runs silent; normal warmth occurs under load but excess heat signals a fault.
