Voltage and capacity limits

The cell chemistry provides a fixed 15.36V output and 42Wh capacity that matches the factory specification. Runtime will vary with screen brightness, workload and battery age. The pack cannot exceed the laptop's original charge controller limits or provide higher wattage than designed. Systems requiring a different voltage or higher capacity will not work with this unit.

Straightforward internal swap

Installation requires opening the bottom case, disconnecting the old pack and connecting the new one using the existing cable. Most users complete the swap in under ten minutes with a small Phillips screwdriver. Common issues include forgetting to disconnect the internal battery in BIOS first, damaging the fragile ribbon cable or failing to seat the connector fully. Calibration cycles may be needed for accurate percentage reporting.
