11.55 V 41.7 Wh Li-ion polymer replacement battery

This 11.55 V lithium-ion polymer pack delivers 41.7 Wh from three cells. It is built as a direct replacement for the HP part numbers HT03XL, HSTNN-LB8M, HSTNN-UB7J, HSTNN-IB8O, HSTNN-LB8L, HSTNN-IB8OL, HSTNN-DB8SL and HSTNN-DB8R. Owners of compatible Pavilion and 240, 245, 250, 255, 340 and 348 G5 or G7 models can restore original run-time with a new, unused unit.

Check your HP part number

Confirm that the original battery carries one of the listed part numbers such as L11421-421, L11421-422, L11421-542, L11119-855 or the HSTNN codes above. The pack fits 14 inch, 15 inch and 17 inch Pavilion chassis including the 14-CE, 14-CF, 14-CK, 14-CM, 14-DF, 14-MA, 14Q-CS, 14Q-CY, 14S-CF, 14S-CR, 15-CS, 15-CW, 15-DA, 15-DB, 15G-DR, 15T-DA, 15T-DB, 17-BY and 17-CA series as well as the 240 G7 and 340 G5 lines.

Replaces an exhausted or swollen HT03XL pack

Swap this in when the factory battery no longer holds a useful charge, shows physical swelling or triggers a capacity warning in the BIOS. The 41.7 Wh rating matches the original specification so run-time returns to as-new levels. It is not suitable for laptops that require a different voltage, a higher watt-hour rating or a different mechanical form factor.
