Review on ๐Ÿ”‹ Kastar 2-Pack 1.2V Ni-MH AAA 1000mAh Rechargeable Battery with Tabs | Ideal for Electric Razors, Toothbrushes, High Power Static Applications, Telecoms UPS, Smart Grid, Electric Mopeds, and Waterpiks by Chris Ferguson

Worked as expected: AAA

My WaterPik toothbrush batteries need replacing. These batteries have a longer service life than original batteries. The problem was that the original batteries were connected together (+ to -) and I had to connect the circuit. I used a soldering iron and with patience I was able to make the connection. Not pretty, but it works. After assembly I placed the toothbrush on the charging station and the batteries took about 15 hours to fully charge. In daily use, it takes a short time to charge after charging.

Pros
  • Battery dimensions: 0.41" x 1.73" (10.5mm x 44mm)
Cons
  • I will add later
