You are buying a new Yuasa replacement battery to fit certain Braun Oral-B and other manufacturers' toothbrushes, including some older versions of the Braun Oral-B Vitality (Type 3709), Vitality Sonic (Type 3737) and AdvancePower electric toothbrush that were originally fitted with Ni-Cd batteries.

If your toothbrush was fitted with a Ni-MH battery of this size we have replacement Ni-MH versions available through our separate eBay listing here.

This high-capacity industrial-grade rechargeable battery is fitted with solder tags ready for you to give your toothbrush a new lease of life.

• Length: 49mm (suitable for replacing 48mm, 49mm, 50mm and 51mm long batteries)
• Diameter: 14mm
• Voltage: 1.2V
• Capacity: 700mAh
• Chemistry: Ni-Cd (NiCd, NiCad)
• Brand: Yuasa
• Solder tags at both ends for soldering

This is not a suitable replacement for batteries marked NiMH, Ni-MH, 3.7V, 3.6V, Li-ion, Lithium-ion or Lithium.

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.
