Top Capacity Japanese 42mm x 17mm NiMH Tagged Electric Toothbrush Battery from FDK with offset solder tag for Braun Oral-B Triumph v1 models

Out of stock


This is a top quality FDK brand replacement battery exactly the same as the original Sanyo/FDK battery fitted to many Braun Oral-B  Triumph v1 models.

The battery is fitted with an offset solder tag on the negative terminal to correctly fit the Braun Oral-B Triumph Professional Care v1 models which have a built-in LCD screen (type numbers 3731, 3738 and 3745 only). Just solder it into your Triumph toothbrush to give it a new lease of life. Made in Japan by FDK, you won’t get a better quality battery than this!

It is strongly recommended that you open up your toothbrush before ordering to double-check the measurements as some Triumph v1 models are fitted with a 49mm long battery. This battery is 42mm long and 17mm diameter. Other sizes are available in our online shop.

See our guides section for instructions on replacing your toothbrush battery.
