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 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.

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 thought this was a bit expensive for what it is, but I am happy with it.My Oral-B io8 lasted about a year before it suddenly completely stopped holding a charge.I do not store my toothbrush on the charger, and keep a fairly close eye on the battery status. This replacement snapped right in, and so far is performing well.

Fit perfectly for my Oral B IO9

Had not really noticed that my toothbrush had been progressively operating less efficiently but was having issues with the charge not lasting. Dropped this in and not only does the power last longer that the original, it seems that the performance has been restored as well.

We just had this battery for a few months and it started failing. Would not recommend

I had purchased an OralB 8 gennegation 2 ½ yrs ago when it quit on me. I watched a YouTube video on how to replace the battery and this did the trick. Good as new for the price of this battery.

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...
