HQRP 2-Pack Batteries Compatible with Braun 8985, BS5771, Type 5497, 8975, 8986, 8987 Razor/Shaver Plus Screwdriver

Excellent battery, easy to install, and saved my expensive Braun unit from being replaced while everything else still worked great.

These batteries breathed new life into an otherwise dead shaver. Familiarity with soldering is required, but there are great youtube tutorials on how to disassemble your shaver and replace the batteries. It was even handy to receive the screwdriver too, although the coasters were a cheap and pointless addition to the package.

The batteries were very easy to install. The tabs that are tack welded to the battery ends could be replaced by a wire to make it even easier to install.

My shaver is like a brand new shaver now. The batteries came fully charged and work great. Just make sure you have decent soldering skills because the batteries are soldered to the circuit board. No instructions included so you're on your own figuring out how to do it.

Beyond my soldering skills. Polarity was not clear

It does you no good to buy new batteries for a razor if there is no instructions on how to install. Razor manual doesn't show how to install either. So unless you are a repairman & know how to repair you are screwed!

Wish I had known about these replacement batteries earlier. My Braun batteries stopped retaking charge more than a year ago. I bought a cheaper razor as I didn't want to spend $300 on a new one. When I read online that you could replace the batteries I bought these along with a soldering kit. The total cost was u dear $30. It took me multiple attempts to get the soldering right but now my razor is working just fine.

Transformed my shaver back to like new condition. You do need to solder the batteries in, but it wasn't a problem for me. I didn't even have to look for a torx driver.
