Built-in protections guard against short circuit, overheat and overload conditions. The cell chemistry maintains reliable output across the full 63 Wh capacity without sudden voltage drops.

Verify your original battery part number

Match the part number on your existing battery against the compatibility list including GA04, GA06, HSTNN-C50C and HSTNN-OB74. Confirm the original pack is rated at 14.4 V and uses an 8-cell layout. This unit will not suit laptops that require a different voltage or cell count.
