Direct Replacement Battery

This Estry Ni-MH cell matches the original 1.2V 2000mAh specification for DentaCare toothbrush models including EW1211w, ES-RT81 and ES-7103. It fits the exact 63.0 x 14.1 x 14.1mm form factor and weighs 48.5g. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards for safe operation.

Sustained Daily Cycling

Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits during repeated charge cycles. The 2.4Wh capacity delivers consistent power for regular brushing sessions without sudden voltage drop. Chemistry and construction are tested to maintain performance across the one-year battery pack lifespan.

Upgrade From Depleted Cells

Replaces worn OEM packs carrying part numbers such as WES7038L2506, WER221L2506 or EW1211RRB84W when runtime has fallen below useful levels. The jump is worth it if your current cell no longer holds a full day’s charge. Not for users needing higher capacity than 2000mAh or a different voltage platform.

Questions about this item

Does the 1.2V 2000mAh Ni-MH cell generate noticeable heat during all-day use?

The 1.2V 2000mAh Ni-MH chemistry runs cool during continuous daily operation; normal hand warmth is the only heat you will feel.

Must the DentaCare toothbrush already be one of the listed models such as EW1211w or ES-RT81 for this pack to fit?

Yes — the 63.0 x 14.1 x 14.1 mm pack replaces the original only in the listed DentaCare models including EW1211w, ES-RT81, ES-7103 and the other named variants.

Will the 2.4Wh replacement work in an older handle that originally used a lower-capacity Ni-MH cell?

The 2000mAh 2.4Wh cell fits the same 63.0 x 14.1 mm cavity and 1.2V rail, so it powers older compatible handles without modification.
