Replace Battery for Braun Oral-B iO Series iO10, iO4, iO5, iO6, iO7, iO8, iO9 Toothbrush Type 3753, Type 3758, Type 3776, Type 3794, UR14500AC Rechargeable Battery

This battery worked well for my Oral-B. I bought it based on the reviews. The value for the price was perfect. It match the previous one ad the function has been wonderful. Would buy again.

Battery didn't work at all. Got it for my Oral B IO 7 toothbrush. Made sure it was in correctly and tried seeing if it just needed charged. Sat it on the charger and still a no go.

This company treated me extremely fairly. I had trouble getting the first battery installed, didn't seem to work right. They sent me a replacement battery, and the same thing happened. I think I messed up during the installation, a tiny chip of the plastic cover came off the OralB. The company allowed me free return of both batteries, and I then bought a new toothbrush. They were easy to deal with, very fair to me.

Fit perfectly for my Oral B IO9

After 2 1/2 years, the original battery on my Oral-B iO9 was only lasting about 4 to 5 days. Now that I have this new battery installed the charge is at about 76% after using the toothbrush 2 times a day for 5 days.Very pleased with the results!I want to purchase a second battery for my wife's toothbrush, but now the battery is out of stock. So sad...

Beware ~ failed after first full charge cycle. Lasted ~ 4 days and was dead after that. Would not charge again. Then, I have to pay to ship it back for a refund…. I’ll just throw away and warn others that it will cost you more in shipping and time to return, than the refund value.

I replaced the battery in my Oral-B iO electric toothbrush with this new battery, and my toothbrush now works like new. Buying a new battery is a lot cheaper than buying a new one Very easy to install. Videos on Youtube

Worked Great !
