You are buying a Highpower brand replacement battery to fit certain Philips Sonicare toothbrushes that use a Lithium-ion battery of this size with offset legs, such as DiamondClean, FlexCare, HealthyWhite and EasyClean models.

This high-capacity rechargeable battery is fitted with the correct L-shaped offset solder legs for easy fitment and soldering. This battery is only suitable for replacing other Lithium-ion batteries and cannot be used where the original battery is Ni-Cd or Ni-MH chemistry. Lithium-ion batteries can ignite if short-circuited so great care must be taken when handling and fitting to avoid short-circuits.

These are genuine Highpower batteries as originally fitted to various batches of Li-ion powered Sonicare toothbrushes, and at 750mAh are an upgrade over lower capacity Sony, Sanyo and Murata batteries that were also fitted.

• Length: 49mm (suitable for replacing 48mm, 49mm, 50mm and 51mm long batteries)
• Diameter: 14mm
• Voltage: 3.6V (direct substitute for 3.7V batteries)
• Capacity: 750mAh
• Chemistry: Lithium-ion (Li-ion)
• Brand: Highpower
• Fitted with correct solder legs at both ends for easy installation and 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.
