Replacement Battery for Sony WF-1000XM4 Case

This Cameron Sino cell replaces the original LP702428 pack inside the Sony WF-1000XM4 charging case. It delivers 500mAh at 3.85V for 1.93Wh capacity and weighs 9.0g. The fully decoded chip works like the factory battery and includes overcharge, over-discharge, over-voltage and short-circuit protection.

Check Model and Part Number Before Ordering

Verify that your charging case is the exact WF-1000XM4 model and that the original battery bears part number LP702428. Confirm the connector matches and that the case dimensions accept a cell measuring 29.80 x 23.10 x 7.00mm. Installation videos are widely available but require careful disassembly of the sealed case.

Restores Case Runtime to Factory Level

The cell restores the charging case to its original runtime when the old pack no longer holds a charge. It is worth fitting when the case cannot fully recharge the earbuds or shuts down prematurely. Buyers needing higher capacity than 500mAh or a different form factor cannot use this battery.

Questions about this item

Does the box include the charging case or only the replacement battery?

Only the replacement battery is supplied; the Sony WF-1000XM4 charging case itself must already be owned.

How do I confirm this LP702428 cell is the correct one for my case?

Match the part number LP702428 and dimensions 29.80 x 23.10 x 7.00 mm against the original battery label inside your case.

What does the 500 mAh rating actually deliver in daily use?

It restores the case to its original 500 mAh / 1.93 Wh capacity at 3.85 V, giving the same number of earbud recharges as when the case was new.
