Replacement Battery for Mackie FreePlay
This 7.4 V nickel-zinc pack delivers 5200 mAh and 38.48 Wh, matching the original J22622 specifications. It fits the Mackie FreePlay and FreePlay Portable PA system, providing a direct swap for the factory cell. A decoded chip ensures the host recognises it like the original unit.
Practical limits of nickel-zinc chemistry
Nickel-zinc cells operate at 7.4 V and reach full performance after two or three complete charge cycles. Do not use low-quality third-party chargers, as they shorten service life. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection for safer operation.
Upgrades from a depleted or failing original pack
When runtime drops or the PA system shuts down early, this replacement restores full portable operation. It is not for users who need a different voltage, capacity or form factor. The jump is worth it once the original cell no longer holds a usable charge.
