Replacement Battery for Oral-B Triumph 4000

This Estry Ni-MH cell is built as a direct replacement for the Oral-B Triumph 4000 electric toothbrush. It matches the original specifications and fits the handle without modification. The pack contains a single rechargeable battery ready for installation.

2000 mAh Capacity and 1.2 V Output

The capacity and voltage are the decisive figures for correct operation. A 2000 mAh rating at 1.2 V delivers the expected run time and charging behaviour for the Triumph 4000. Using a cell with different values would cause poor performance or damage.

Typical Runtime and Limits

A full charge powers normal daily brushing for several days before the handle needs to return to its charger. The 2.4 Wh energy rating supports regular morning and evening use. Heavy users who brush more frequently or use high-power modes will see shorter intervals between charges.

Questions about this item

How long will the 2000mAh capacity run my Triumph 4000 between charges?

The 2000mAh cell stores 2.4Wh at 1.2V, matching the original specification so brush time per charge is the same as the factory battery.

Does the 1.2V Ni-MH chemistry limit charging speed or require a special charger?

It uses the standard 1.2V Ni-MH voltage the Triumph 4000 charging base already provides; no extra charger or protocol is needed.

Will the 43.15 x 16.95 x 16.7mm case and 81.8g weight fit the Triumph 4000 handle without modification?

Yes, those dimensions and the 81.8g mass are built to the original 3745, 3761 and 3762 part numbers for a direct fit.
