Polarity was not marked on battery I received, had to check with voltmeter to check polarity. (Posted on 3/9/2024)

This razor has been with me since new, which is at least 16 years. Seral years ago, I had to keep it plugged in when shaving. At the time I didn't even think about battery replacement.
Here it is 2022. The internet, with Youtube, Ebay, et al. You can find anything. That is how I discovered ShaverOutlet.com. Found the batteries and watched a Youtube video. Really is a piece of cake to do this. The solder tabs make all the difference. Also, this shaver is made up of individual modules which are connected by metal contacts. Most of mine were filthy and discolored with a coating made up of old lubricants within the razor and I'm sure some from without. I cleaned them with alcohol, then a pencil erasure, then a very light coating of automotive dielectric grease used for light bulbs and the like.
So, with information from ShaverOutlet.com and their batteries, my Braun runs like it did when I took it out of the box. I felt really secure knowing that I was buying these batteries from someone with a vested interest. What more can I say?

I bought a replacement battery and shaver head and foil. Got the battery soldered in and the head and foil are the right fit. I'm glad I can still get parts for this trusty shaver. (Posted on 2/3/2022)

I am so glad I have found your site. I purchased 2 replacement batteries. They are working perfectly in my Remington R-6150. It would be nice if the batteries could be sold and packaged as the original set: Pre-soldered on one end. It is only a suggestion. (Posted on 6/27/2021)

Had my Braun 5645 for over 12 years and batteries were getting tired only holding charge for 5 shaves. Did a search for trying to find replacement batteries and Shaver Outlet helped with what part# I needed as well as a tip on replacing them . After 3 weeks batteries are still going strong and installing was a snap. Will be back when needed in the future (Posted on 4/15/2021)

I gave my expensive cordless shaver new life by replacing its batteries for a fraction of the price of a new shaver. The new batteries came with solder tabs spot welded onto them so all I needed was a soldering iron and a screwdriver to complete the job. (Posted on 4/1/2021)

Had to make the metal tangs narrower to fit them through the slot, but it works great in my Norelco shaver. Thanks! (Posted on 2/10/2021)

This battery fits just great. Thus the shaver was up and going quickly. (Posted on 2/10/2021)

I bought battery, shaver head, screen and cover for my old Braun. They are perfect. The battery last for a long time between charging. I again bought extra screen for spare. (Posted on 8/15/2020)

order made it in very short time . the only problem was no markings on batteries. But after looking at batt. configuration and using a meter they were installed very simply First shaver working GREAT ! Second one is for backup.

I would give SHAVER OUTLET a 9 out of 10 but it doesn't go that far.
IF these batteries last as well as the original I will be very happy.

I will go to SHAVER OUTLET FIRST for shaver supplies.

GOOD JOB ! (Posted on 6/15/2020)
