You are buying a brand new, genuine FDK toothbrush battery to replace the original FDK or Sanyo battery as fitted to certain Braun Oral-B toothbrushes, including some versions of the Type 3728 model and most Triumph v2 models (most versions of Types 3761, 3762 and 3764).

Please open your toothbrush to check the length and diameter of your battery before ordering as Braun fitted different sizes to the same models depending on year of manufacture and region. For other sizes please see our multi-size listing.

• Length: 42mm (suitable for replacing 41mm, 42mm, 43mm and 44mm long batteries)
• Diameter: 17mm
• Voltage: 1.2V
• Capacity: 2150mAh
• Chemistry: Ni-MH
• Brand: FDK
• Made in Japan
• Solder Tags: 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.
