I saw a drawing of a man pushing a large Boulder. The caption under it said even if it’s free, sometimes it’s just not worth it. This is how I feel about this battery. It wasn’t free but at any price it’s not worth getting. I installed it into my toothbrush, let it charge for 24 hours, until it was fully charged. It wouldn’t complete one cycle. It went dead and the red out of power light came on. Let it charge overnight, same thing. I thought maybe I’d done something wrong so I took it back out and replaced it with my original battery. That one charged and I was able to get a few cycles. Thought I’d give the new battery another chance, reinstalled it and the exact same thing happened. Less than one cycle. I finally decided to spend the extra money and get an oem battery. Charged and works great. I would have saved a lot of time and frustration just doing that in the first place. Maybe you’ll get a battery that works great the first time, apparently some people have. I just don’t think it’s worth the risk to save a couple of bucks.

Worked for my older model Braun/Oral-B tooth brush. The tooth brush is designed to make it hard to change the battery and so, they are only designed to last about 5 years forcing out to buy a whole new tooth brush. Being an egineer who likes to fix things and not very happy with the practice of design absolencence I though I would try taking my tooth brush apart and replace the dead battery. Tooth brush is about 10 years old and was no linger charging. Replacing was a bit of a process and there's a trick to opening up the tooth brush. You can find videos online on how to do it. You basically have to take the whole thing apart, inclyding desoldering the old batter and the mtor from the circult board. You can do it with some patience and a magnifying glass. Got it all back together and my tooth brush runs as good as new. Should get another 10 years out of it. This seller was the only place where I could find the exact battery I needed for my model. Battery came next day. Very happy with the seller and the quality of the battery. Great buy. Ease of installation? No, not buy a ling shot. It's a process, but can be done if you have some soldeting skills.

First one lasted almost 14 months, where the original OEM battery lasted nearly 10 years. Foolishly bought another HQRP battery and it only lasted almost two months in early 2024. Just now replaced it with a Cameron Sino CS-OBT850SL for $15-ish. It reached full charge after about 8 hours and worked great, but only time will tell if it was a good choice. Fortunately, I didn't desolder the original battery leads from the toothbrush. I detached the leads from the original battery and left them standing so that I can simply swap the battery out similar to that of a flashlight - no soldering required.

Restored life to my older Braun 3762 toothbrush! Also called a triumph 2. So happy I did the replacement. It was tricky, but the video repair looked straight forward. My brush wouldn't last the full 2 minutes this replacement resolved that and it is still going strong at the end of the timer. Goodluck, take your time, you can do it!

The first battery I purchased it's welded terminal broke off. The replacement battery required multiple charges before it started acting normal. maybe this battery was stored without a charge for too long but it arrived with no charge at all. After 5 times being recharged it performs as a new battery that I had expected.

I can see why some people broke their leads. They are offset on the original and straight on this battery. They are also much thinner on the replacement. I'm a careful person and with some precision pliers was able to bend them correctly into position and solder them to the board. Its a simple process, but I wouldn't fault someone for breaking the lead off. You then fold them onto the board and solder away.I started charging and I had two bars within 5 hours or so. The next morning it wasn't fully charged but I pulled it off anyway. It had one bar and wouldn't even turn on. I checked my soldering and it was still holding strong. Negative and positive were where they should be. I tried charging again, this time for the full 24 hours and still couldn't get it to turn on. I decided to reinstall my old battery and now I am back to charging every night.This is not a quality product. Read through the reviews. Its a piece of junk.

Was able to change this out in a few minutes, works like champ.. I put it in my charger first to make sure it would take a charge. Not that hard if one has the skills. P.s. the top seal can be pressed in place using a deep well socket. After watching a video that part was not explained. I now have a new toothbrush. So far this new battery has been performing as expected. Would I buy it again, no!....at first I thought this was the one, but I bought this in August I think last year, anyhow it is now October a year laterand it died. I would have hoped for more than that. It was an easy project, but I will just buy a new toothbrush.

I replaced the battery in my Oral B toothbrush with this one. It appeared to charge normally, taking 24 hours for the first charge. I attempted to use the toothbrush and after the first 30 second cycle, the battery was fully discharged and the toothbrush stopped completely. The charge indicator was flashing red. I placed the toothbrush back on the charger and it took 24 hours again to show full charge. I attempted to use the toothbrush again. Same -- stopped after 30 seconds and showed full discharge. I thought maybe the toothbrush itself had failed, but I replaced this battery with one from another source and it functions normally. This battery is either faulty or junk.
