Replacement Toothbrush Battery for some Braun Oral-B Triumph Type 3731 3738 3745
Triumph v1 toothbrushes have type numbers 3731, 3738 and 3745 marked on bottom of handle and have a built-in screen. This battery is made with the negative solder tag specially offset to fit versions of Braun Oral-B Triumph v1 toothbrushes that were fitted with 49mm long batteries.
This battery is 49mm long but Braun sometimes fitted 42mm long batteries. Please open your toothbrush to check the length of your battery as Braun fitted the two different sizes depending on year of manufacture and region.
Length: 49mm (suitable for replacing 48mm, 49mm, 50mm and 51mm long batteries)
Type: 49 mm x 17 mm Offset Tagged
Brand: GP Batteries
Tagged at both ends-Offset negative tag to fit Braun 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.
