Compatible replacement battery

The Beisite NP03XL is a new lithium-ion laptop battery built to replace original part numbers NP03XL, HSTNN-LB6L, HSTNN-UB6L, 761230-005, 760944-421 and 760944-541. It fits HP Pavilion and Envy x360 convertible models including the 13-A010DX, 15-U437CL, 15-U473CL, 15-U483CL and 15-U493CL series. The black pack ships as a single unit with a 12-month warranty.

43Wh at 11.4V

This battery delivers 43 watt-hours at 11.4 volts, the exact energy rating required by the listed x360 platforms. Matching both voltage and capacity ensures the laptop’s power management recognises the pack and reports charge levels correctly. A different voltage or capacity would prevent proper operation.

Drop-in fit for x360 chassis

The pack slots into the existing battery bay without adapters or cable changes, freeing the user from hunting for proprietary connectors. It restores mobile runtime on supported Pavilion 13 and Envy 15 convertibles. Buyers whose laptop uses a different part number or form factor will need a separate replacement.

Questions about this item

What does the 43 Wh capacity mean for daily runtime on an Envy x360?

A 43 Wh pack typically delivers several hours of mixed office work on these convertible models; actual time varies with screen brightness, workload and battery health.

What voltage does the 11.4 V lithium-ion battery use to communicate with the laptop?

The 11.4 V nominal voltage matches the original HP specification, so the Envy or Pavilion x360 recognises the pack and reports charge level normally.

Will the NP03XL fit inside a Pavilion 13 x360 Convertible PC without modification?

Yes, the NP03XL is built to the same form factor as HSTNN-LB6L and slides into the battery bay of the listed Pavilion 13 x360 models.
