Will this battery restore full original runtime and are there setup tips?

When installed and conditioned properly, the pack will deliver run times comparable to a fresh original battery under similar usage. To achieve optimal capacity, charge fully before heavy use and allow a few charge/discharge cycles to help the system calibrate battery reporting.

• Verify part numbers on your original battery if uncertain about model compatibility
