Installation notes and common issues

The battery ships ready to install and matches the original form factor for the listed machines. L20L4PD3 and L20M4PD3 are cross-compatible despite a voltage difference, so either variant may be supplied. Take care to disconnect the internal connector before removing the old pack.

Practical limits of the 71Wh capacity

Runtime depends on the workload and screen brightness of the host laptop. The 71Wh rating sets the total energy available per charge cycle. Users who need longer unplugged time or a higher-wattage cell will need a different capacity tier.
