### ⭐⭐⭐⭐⭐ Works!
*by J***K on May 2, 2023*

I bought to repair a Braun Toothbrush. There are several different batteries depending on the model. One size does not fit all! Buying the battery with the solder tabs already welded is more expensive but will make installation much easier. I own a battery welder, but for a couple of dollars more it wasn't worth the time or effort! A YouTube search for your model will help in disassembly and identifying the correct battery. These are an exact fit sort of thing, close won't fit! Despite showing charged, my toothbrush seem to struggle, like 1/2 speed. This brought it back to like new. The videos will help, but it is easy to screw up and toast your big bucks toothbrush. You were warned ⚠️***************************************I neither received nor solicited recompense in any form for this review. Solicitations to change or "enhance" reviews are always reported to Amazon without exception. Free items or money are joyfully accepted, THEN IMMEDIATELY REPORTED TO AMAZON!! THANK YOU!!!! The observations are my own without any outside influence or input. Your experience may differ from my own! Do your own research and comparisons prior to purchasing, don't rely solely on my observations. I recommend purchasing only from Prime sellers as my experience with "marketplace" sellers has been mostly negative, often drop shipping from China to the USA so it has a USA postmark. That said, do your own research prior to purchasing any products from the Internet!?

### ⭐⭐⭐⭐⭐ Perfect replacement, easy to install, great instructions.  Need good tools and patience
*by S***S on September 13, 2021*

This battery is perfect for the Braun Oral-B Triumph (make sure you have the right length battery!), with narrow and offset tabs that make installation very simple. There is no need to bend or reshape the tabs, they fit directly into the existing holes (after removing the old battery and cleaning up the pads). All that is required is to shorten them. The provided (and available online) instructions are very clear, with pictures that show how the process should go.Since installation a week ago the toothbrush shows 3/4 indicated charge after using it twice a day, I fully expect another three or four weeks (maybe?) before it needs to be charged again. Before replacing the battery the toothbrush would make it through one cycle (two minutes) then would be dead. Now it's back to what is was when it was new (at least).Note that replacing the battery requires a good soldering iron, desoldering tools (I used a solder-sucker to remove the old battery and solder wick to clean the battery pad), a T6 screwdriver, and a small wire cutter (to reduce the length of the battery tabs). A small hobby vice comes in very handy as well. Removing the plastic press-fit tip on the toothbrush requires a small screwdriver (or other thin blade), putting it back on requires some amount of pressure (I adjusted the jaws of my vice to fit the width of the tip and pushed). Some experience in this sort of work is very useful, it might be a bit overwhelming for someone that has never done small electronics repair. But if you have the tools, and the time, the results are well worth it.

### ⭐ Bad purchase
*by L***N on August 15, 2022*

Not worth the money. Takes more than 24 hours to charge. First time the charge lasted only 3 weeks. The second time it lasted only 2 weeks. I only use it once a day (I have another brush that I also use). It came with the positive side marked by a sharpie.I am assuming that it can’t be returned after already installed by soldering!
