Replacement Battery for Oral-B Triumph 4000

This Cameron & Co Ni-MH cell replaces the original battery in Oral-B Triumph 4000 toothbrushes. It matches part numbers 3745, 3761 and 3762. The green pack delivers 2000mAh at 1.2V for cordless operation.

Ni-MH Chemistry Limits

Nickel-metal-hydride chemistry self-discharges when stored unused for long periods. Capacity drops if the toothbrush sits idle for weeks. The cell is not compatible with the 47mm version of the handle, so verify dimensions before fitting.

Simple Press-Fit Installation

The pack measures 43.15 x 16.95 x 16.70 mm and slots into the handle without tools. Common issues are ordering the wrong version for the 47mm model or forgetting to charge fully before first use.

Questions about this item

Is the CS-OBT850SL the correct version for my Oral-B Triumph 4000?

Yes, the CS-OBT850SL fits the Triumph 4000 and replaces part numbers 3745, 3761 and 3762; it does not apply to the 47 mm variant.

What runtime can I expect from the 2000 mAh Ni-MH cell in my toothbrush?

The 1.2 V, 2.40 Wh pack delivers the same capacity as the original 2 Ah battery, giving comparable brushing time per charge.

Does the 1.2 V Ni-MH chemistry limit charging speed or compatibility?

The cell matches the original 1.2 V specification, so it charges normally in the Triumph 4000 handle without any voltage mismatch.
