Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Mackie FreePlay Portable PA System — 7.4V Li-ion Replacement Battery (J22622)
This is a 7.4V, 6800mAh (50.32Wh) Li-ion replacement battery for the Mackie FreePlay and FreePlay Portable PA system. It fits the original J22622 battery position directly. When the stock cell degrades and the speaker stops holding a charge, this is the part that brings it back.
- FreePlay and FreePlay Portable PA compatibility: Both units share the same 7.4V two-cell Li-ion pack, connector pinout, and BMS communication protocol — so one part number covers the whole FreePlay range. The voltage rail feeds both the Class D amplifier and the Bluetooth radio simultaneously.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a FreePlay unit, monitoring BMS handshake, cutoff voltage, and cell balance. Both cells tracked within 20mV of each other under sustained combined audio and radio draw.
- First-charge protocol for the FreePlay: After fitting this battery, run one full charge cycle before use — the FreePlay's internal battery gauge recalibrates on the first complete charge-to-full cycle, so the on-device LED indicator reports state-of-charge accurately from the start.
Why the FreePlay cuts out under combined Bluetooth and amplifier load
The FreePlay draws from the same 7.4V pack for both the Bluetooth radio and the Class D amplifier. At high volume, the amplifier pull spikes sharply — and if the cell is aged or deeply discharged, voltage sags below the BMS cutoff threshold. The BMS interprets this as a fault condition and disconnects output to protect the cells. Fitting a fresh cell with full capacity eliminates the sag that triggers this behaviour.
FreePlay shows full charge on LED but cuts off after a short time
This happens when a new or long-stored battery arrives at storage voltage — around 3.7V per cell — and the on-device gauge hasn't yet calibrated to the new pack. The LED reads the surface charge, not the true state of charge. Run one complete charge cycle from flat to full before heavy use. After that first cycle, the gauge reads correctly and the symptom disappears.

Frequently Asked Questions
My FreePlay cuts out mid-song at high volume even though the battery indicator shows charge remaining — what's happening?
This is a voltage sag cutoff, not a gauge error. At high volume, the Class D amplifier and Bluetooth radio pull current simultaneously, and if the pack's cells have degraded, voltage drops sharply enough that the BMS trips the output to protect the cells. A fresh 6800mAh pack restores the headroom needed to handle combined peak draw. Fit the new battery and run one full charge cycle before pushing high volume levels.
The FreePlay's talk time seems shorter than expected on the first few uses of the new battery — is something wrong with the cell?
Nothing is wrong. Li-ion cells in portable audio devices typically reach rated capacity after three to five full charge-discharge cycles, not from the first use. The cells need cycling to reach full electrolyte saturation and stable internal resistance. Run three complete charge-to-flat-to-full cycles and measured output duration will increase noticeably each time.
The FreePlay feels noticeably warm near the battery compartment during long sessions — is that a problem?
Some warmth is expected. The FreePlay housing is compact, and the pack is sustaining continuous current draw to both the amplifier and the Bluetooth radio with limited thermal mass around it. If the unit becomes hot to the touch — not just warm — reduce playback volume and allow a 10-minute cool-down before resuming. Check that the battery compartment cover is seated correctly, as a loose fit reduces passive heat dissipation from the pack surface.
