Works great
There are several websites and YouTube videos showing the replacement process. It is not like dropping in a new AA battery however. You have to partially dismantle the toothbrush and soldering skills on a tiny circuit board are required. Review the procedure before you buy. Shipping takes a couple weeks.Verified purchase: YesCondition: New

Pefect Fit. Easy Install if You Can Solder
This replacement works perfectly. I'm now getting two weeks use out of each charge (brushing once a day). This is the second time I've replaced the battery. The last time was five years ago so the battery lasts quite a long time. The YouTube video and how-to web page are totally clear. Pay attention to the warning that you need some basic soldering skills and tools. Using a solder vacuum tube worked well for me but the wicking braid would probably do the job as well. It's much cheaper and better for the environment to get more life out of your Braun by replacing the battery in this way. Next time, I'll order the larger size for even more time between charges (see the how-to web page for an explanation).Verified purchase: YesCondition: New

Installed properly
Doesn’t hold its charge that long. Wanted this to hold its charge as old battery lasted 2-4 days after normal charging/ Usage. This install has not changed anything. Great product but no guarantee it lasts any longer than original equipment . Installed in 2 separate products and expected longer charge to last.Verified purchase: YesCondition: New

good, as expected
Served as a great replacement for my OralB 3728. Toothbrush runs as new. Have only had for a month so can't comment on durability.Verified purchase: YesCondition: New

This battery holds only about 50% of the original factory supplied unit. I should have paid the extra and purchased a well branded product
