Description
This is a top quality FDK replacement battery exactly the same as the original Sanyo/FDK battery fitted to many Braun Oral-B toothbrushes such as the Triumph v2 models (some versions of type 3761, 3762 and 3764) and some versions of the Professional Care type 3728. Also fits certain Philips Sonicare and other manufacturers’ toothbrushes such as the Sonicare Elite.
The battery is fitted with solder tags ready for you to solder it into your electric toothbrush and give it a new lease of life. Made in Japan by FDK, you won’t get a better quality battery than this!
It is recommended that you open up your toothbrush first to double-check the measurements of your original battery. See our guides section for instructions on replacing your toothbrush battery.

Had an older Braun 3728 toothbrush and it wouldn’t run for even two minutes to brush so it was either trash it or get a new battery.
I found Ionic and I decided to purchase the upgraded FDK battery, the small battery was in the toothbrush originally. Took a bit of work to get it in there but with the tutorial that Ionic provides it was a slam dunk. Ordering process was painless and it was shipped to Canada faster than what I’d expected.
Hardest part of the swap was not trashing those fine copper wires at the base to the inductive charger. Used desoldering wick to clean off the old solder and the reassembly was pretty straight forward.
The new battery runs for about 11 days before the red light comes on to indicate it’s time to charge.
I’d do it again in a heartbeat, I rather enjoy stuff like this and to throw the toothbrush away would have been such a waste.
