Replacement battery for MacBook Unibody 13" A1342

This PISKEKAT A1331 lithium-ion battery replaces the original power cell in Apple MacBook Unibody 13-inch models A1342 from Late 2009 and Mid 2010. It is a direct substitute for part numbers A1331, A1342, 661-5391, 020-6580-A, 020-6582-A, 020-6809-A and 020-6810-A. The unit is supplied new and rated at 10.95V 5800mAh.

Practical limits of the Li-ion chemistry

The cell is rated for up to 600 recharge cycles over its service life. Run-time per charge will vary with system load, screen brightness and background tasks, so heavy workloads reduce usable time between charges. Capacity gradually declines with age and cycle count, a normal characteristic of lithium-ion technology. The pack includes built-in circuit protection and holds CE, RoHS and FCC certification for safety compliance.

Installation notes and common issues

Installation requires removing the bottom case of the MacBook, disconnecting the old battery connector and fitting the new pack in its place; a tri-wing or pentalobe screwdriver is typically needed. Common problems include forgetting to disconnect the MagSafe adapter before starting, not seating the connector fully, and failing to calibrate the battery after the first few charge cycles. The product carries a 12-month replacement warranty from the manufacturer.
