This battery replaces part numbers PA5149U-1BRS, PA5149U, 4INP7/60/80, 4ICP7/60/80 and several OEM codes including G71C000GB310. The upgrade is worth it when the original pack no longer holds a useful charge or shows swelling. It fits Z40-A, Z40-B, Z40-C and Z50-A sub-models listed in the compatibility data.

Rated for 500 charge cycles

The cell chemistry is rated for up to 500 full charge cycles while maintaining usable capacity. Built-in protections guard against overcharging and overheating during extended sessions. For best long-term results, the maker suggests discharging to 5 percent then charging to 95 percent for the first three to four cycles. Actual runtime varies with the laptop's power draw and workload.
