Lithium polymer chemistry and 11.55 V rating

The battery uses lithium polymer cells rated at 11.55 V and 4330 mAh, delivering 50 Wh of energy. Voltage must match the original battery exactly; a mismatch will prevent charging or damage the laptop. Capacity determines runtime per charge and cannot be increased without changing the physical pack. Users who require longer unplugged time need a higher-capacity pack that fits their chassis.

OEM-grade cells with built-in safety protection

Manufactured with OEM-grade lithium polymer cells, the pack includes circuitry that guards against over-charging, over-discharging, overheating and short-circuit conditions. The slim 8.0x1.5x0.8 cm form factor fits the internal battery bay of the listed models without modification. Buyers should verify the original part number such as SS03XL or HSTNN-DB8J before installation to ensure correct connector alignment.
