Green Cell Apple MacBook Pro 13" A1278 5900mAh Battery (Li-Po 10.95V) - Ref. A1322 (Refurbished)

Description

The Green Cell 5900 mAh internal replacement battery (part number A1322) is a refurbished spare part specially selected for the renovation, maintenance and refurbishment of the Apple MacBook Pro 13-inch Unibody laptop range (A1278 chassis, Mid 2009 to Mid 2012 generations). Intended for computer repair workshops, Mac-environment specialised technicians and B2B resellers, this refurbished battery is covered by a 3-month warranty and offers an economical and reliable solution to extend the operational life of Apple laptops at a controlled equipment cost.

From an electrochemical perspective, this refurbished module uses a high-density 6-cell Green Cell brand Lithium-ion Polymer (Li-Po) architecture, delivering a capacity of 5900 mAh at a nominal voltage of 10.95V for an accumulated energy of 65 Wh. This configuration ensures a perfectly stable electrical power supply to the motherboard and supports up to 500 complete charge/discharge cycles. The component incorporates an advanced electronic management board (BMS - Battery Management System) responsible for the continuous control of the charging current. This microcontroller provides active protection against overvoltages, deep discharges, short-circuits as well as thermal runaway risks.

The rigid external casing is moulded from heat-resistant high-density insulating polymer, rigorously adapted to the internal footprint of the aluminium Unibody chassis. Installation is carried out under the bottom cover of the MacBook Pro and connects to the motherboard using a secure flat connector. The location of the metal mounting tabs faithfully respects the original anchoring points to ensure perfect mechanical rigidity without creating stress on the trackpad located just above.

Workshop Tip & Usage

Before dismantling the old battery, make sure to completely turn off the MacBook Pro and disconnect the MagSafe charger. Removing the A1322 battery pack requires a Tri-Wing (Y0) screwdriver to remove the specific three-point screws holding the casing to the aluminium chassis. Handle the battery connector with a plastic spudger to avoid bending the pins of the motherboard socket. During initial workshop commissioning, carry out a complete SMC calibration cycle: charge the refurbished battery to 100%, then let the device discharge gradually until complete shutdown before performing an uninterrupted 4-hour recharge on mains power.
