55mAh CP1254-A3 Replacement Battery

This 3.7V 55mAh 0.2Wh lithium-ion pack replaces the CP1254-A3 cell inside Beats Powerbeats Pro earphones. It fits models MV6Y2LL/A, MV722LL/A, MXY72LL/A, MXY82LL/A, MXY92LL/A, MXYA2LL/A and MY592LL/A. The kit includes free installation tools but does not supply a soldering iron. Buyers whose earphones use a different battery code cannot use this part.

Low self-discharge chemistry

Lithium-ion cells hold charge during storage and deliver steady voltage through a typical listening session. The 55mAh capacity matches the original specification so run-time returns to factory levels. No active cooling is required and the pack adds no audible noise. Power draw is limited to the earphone's own charging circuit.

Restores original run-time

The battery suits owners whose Powerbeats Pro cases no longer hold a full day of charge. It is not a higher-capacity upgrade and will not extend playtime beyond the original design. Users who need more storage or a second charging case should look elsewhere. The jump is worth it only when the existing cell has degraded below usable life.

Questions about this item

How do I install the CP1254-A3 battery in my Powerbeats Pro earbud, and what step often goes wrong?

Open the earbud casing, desolder the old CP1254-A3 cell, then solder the new 3.7V 55mAh pack in its place; the step most people miss is applying too much heat and lifting the flexible circuit pads.

What maintenance or replacement will the 55mAh lithium-ion pack need over time?

The 0.2Wh cell ages with each charge cycle; when run-time drops noticeably, replace it with another CP1254-A3 pack using the included tools.

What limit appears first during extended listening sessions with the replacement battery?

The 55mAh capacity sets the runtime ceiling; under continuous play the earbud will shut down once the 3.7V pack reaches its low-voltage threshold.
