    Replacement Toothbrush Battery for Braun Oral-B Triumph v2 3761 3762 3764 3728


    • New FDK replacement toothbrush battery to fit certain Braun Oral-B, Philips Sonicare and other manufacturers' toothbrushes.
    • This top-capacity, Japanese-made battery is fitted with solder tags ready for you to give your electric toothbrush a new lease of life. As well as other models, this battery will fit certain versions of the Braun Oral-B Triumph v2 (Types 3761, 3762 and 3764) and versions of the Braun Oral-B Type 3728 toothbrush that were originally fitted with a 42mm by 17mm diameter battery. However, some Type 3728 versions were fitted with a smaller 42mm by 14mm diameter battery so open up your toothbrush to check before ordering!

    Main features:

    • Length: 42mm (suitable for replacing 41mm, 42mm, 43mm and 44mm long batteries)
    • Diameter: 17mm
    • Voltage: 1.2V
    • Capacity: 2150mAh
    • Chemistry: NiMH
    • Brand: FDK
    • 3mm-wide tags at both ends for soldering


    • It is strongly recommended that you open up your toothbrush before ordering to double-check the battery measurements because different sizes were fitted to different batches of the same model. You must be competent at soldering to fit this replacement and the fitted tags will need trimming to suit your toothbrush.
    • Our battery tags are carefully welded into place using specialist, instant resistance-welding machines for batteries. Do not attempt to solder anything directly onto an untagged Ni-MH, Ni-Cd or Lithium battery as the heat will cause internal damage and the battery might combust. Unless otherwise stated our batteries are fitted with extra-narrow, 3mm-width solder tags for maximum flexibility in fitting your toothbrush.
