Physical Fit And Electrical Limits

The cell measures 31.44 by 17.40 by 6.30 millimetres and weighs 5.8 grams. It delivers a nominal 3.7 volts and carries ISO9001, RoHS and CE certification. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. The supplier cautions against storage above 60 Celsius and warns never to disassemble or expose the cell to fire or water.

Capacity And Runtime Headroom

Rated at 220 milliampere-hours and 0.81 watt-hours, the battery restores the case's ability to recharge the earbuds multiple times. A fresh cell reaches peak performance after two or three full charge cycles. Users who need more stored energy than this single cell provides will require a higher-capacity case or a power bank instead.

Questions about this item

Should I choose the 220mAh version or a different capacity for my WF-SB700 charging case?

This battery is supplied as a single 220mAh / 0.81Wh cell that matches the original specification for the WF-SB700, WF-SB700N, WF-XB700 and WF-XB700N charging cases; no alternative capacity is offered for these models.

What does the 220mAh rating actually deliver once the battery is inside the charging case?

The 220mAh cell at 3.7V provides 0.81Wh of energy, restoring the case's ability to recharge the earbuds multiple times and returning standby duration to the level the case had when new.

What connector standard does this battery use and what does it limit in practice?

The battery uses the original Sony plug-and-play connector for the listed charging cases; the built-in protection circuit limits over-charge, over-discharge, over-voltage and short-circuit current to keep the case operating within safe parameters.
