This is a new replacement battery from GP Batteries fitted with specially aligned solder tags to fit some of the Braun Oral-B Triumph v1 range of toothbrushes. Triumph v1 toothbrushes are all marked with type numbers 3731, 3738 or 3745 on the bottom of the handle.
This battery is specially fitted with an offset solder tag on the negative terminal and it fits versions of the Braun Oral-B Triumph Professional Care v1 models that were made with a 49mm long battery. It is strongly recommended that you open up your toothbrush before ordering to double-check the measurements of your existing battery as some versions of the Triumph v1 models were fitted with a shorter 42mm length battery. Other battery lengths and diameters are available in our online shop.
See our guides section for instructions on replacing your toothbrush battery.
