Do your electric razor’s batteries not hold a charge any more? Save yourself some money and not add to the growing pile of e-trash. Changing out the batteries is easier than you think. You’ll only need a couple of tools and a little time. The steps are pretty easy.
- Take your electric razor apart to find out what type of replacement battery you need.
- Buy your replacement batteries. There is a link below for inexpensive replacement batteries.
- Remove your old batteries
- Solder the new batteries and place.
- Reassemble your razor and test it.
What started this is I have an older Remington R845 rechargeable electric razor that stopped holding a charge.
The video takes you through the steps described above.
Taking Your Razor Apart
This is a matter of removing a couple of screws using a screwdriver. If you’re changing the batteries out a Remington, like the one in the video, you’ll need a #1 philips screwdriver. This is a slightly skinnier than a standard #2 philips you would normally have lying around the house.
This video is pretty good if you need a refresher on how to solder.
Buying Your Replacement Batteries
There are a couple of ways to buy your replacement batteries.
- Do a google search using the model number of your razor.
- Find the original battery model number and search using that
- Find the original battery voltage and milliamps and search using that information.
Using the model of your razor, you might want to try shavers.com or search Amazon.com to see if you can easily find the replacement rechargeable battery you’re looking for. I found this site through a series of google searches.
Pre-tabbed Batteries or Solder Your Own Tabs
The first thing you might notice when you open up your electric razor and look at the old batteries is they have a tab soldered on them by the manufacturer.
Your options are to
- Purchase pre-tabbed batteries
- Buy or find replacement rechargeable batteries and re-solder the old tabs on the new batteries.
The replacement batteries used in the video above had the tabs already soldered on them. They were purchased from shavers.com and were only $3 a battery shipped. If your batteries are a standard size, Amazon has some cheaper than $3.
Soldering Tabs on Batteries
If you decide to reuse the tabs from your old batteries and solder them on to the new ones the video below does a great job showing you how to do that.
Replacing your rechargeable batteries isn’t that hard. It just takes about 30 minutes even if you’ve never done anything like this before. Just take your time and use a camera to document how things were originally put together.
- Elenco Electronics ST-12 Soldering Tool Kit – This kit is similar to the inexpensive one I used in the video.
- Craftsman 17-Piece Screwdriver Set, #31794 – Try whatever screwdriver you have around the house to see if it’ll work. If not it’s always good to have a set of screwdrivers of different sizes.
