    Genuine FDK Toothbrush Battery for some Braun Oral-B Triumph Type 3731 3738 3745


    • New and genuine FDK rechargeable battery to replace the one in some Braun Oral-B Triumph v1 toothbrushes.
    • Triumph v1 toothbrushes have type numbers 3731, 3738 and 3745 marked on bottom of handle and have a built-in LCD screen. This Japanese-made FDK battery is fitted with the negative solder tag specially offset to suit versions of Braun Oral-B Triumph v1 toothbrushes that were fitted with 42mm long batteries.

    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
    • Tagged at both ends - Offset negative tag to fit Triumph v1 models


    • 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.
