Replacement Battery for Sensonic Plus Toothbrush

This 2.4V 700mAh Ni-MH pack replaces the original BK-4MCCE cell in Sensonic Plus SR-3000, 900 and SR-3000E sonic toothbrushes. It restores the runtime the brush had when new and fits the existing charging stand without modification. The pack measures 43.36 x 20.5 x 10.46mm and weighs 47.2g.

Ni-MH Chemistry and Charging Limits

Nickel-metal hydride cells accept a steady trickle charge from the toothbrush base rather than a fast-charge protocol. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are built into the pack to prevent damage during normal docked charging. The chemistry delivers 1.68Wh of energy at the rated 2.4V.

Capacity and Runtime Headroom

At 700mAh the battery supplies enough charge for several days of typical twice-daily brushing before the handle needs to return to the stand. Heavy users who brush longer or more frequently will see the indicator fade sooner and should plan for a nightly dock. The pack is not suited for devices that draw higher current or require a different voltage.

Questions about this item

How do I know this is the right capacity for my toothbrush?

The pack delivers 2.4 V and 700 mAh, matching the original BK-4MCCE specification for the Sensonic Plus SR-3000 and SR-3000E models.

What does the 1.68 Wh rating tell me about daily use?

It means the cell stores 1.68 watt-hours, giving roughly the same runtime per charge as the factory battery in the SR-3000 900 sonic toothbrush.

Does the Ni-MH chemistry limit charging speed or compatibility?

The battery uses standard Ni-MH chemistry at 2.4 V, so it charges on the toothbrush's original dock without special protocols or voltage negotiation.
