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.
