You are buying a new GP Batteries brand replacement battery to replace the one in many 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 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 42mm long batteries.

This battery is 42mm long. Please open your toothbrush to check the length of your battery as Braun fitted two different sizes to their Triumph v1 models depending on year of manufacture and region. If yours is fitted with a 49mm long battery please see our multi-size toothbrush battery eBay listing.

• Diameter: 17mm
• Voltage: 1.2V
• Capacity: 2100mAh

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.

To remove the internal LCD screen for access to the battery solder points you will normally require a screwdriver with a star-shaped tip. These are available through our eBay screwdriver listing here.

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.
