I have this old electric razor that was long dead…
It wouldn’t hold a charge, so the rechargeable batteries were shot. I opened it up and luckily the thing used the standard “AA” size.
Got some cheap replacements from Fry’s and soldered them in. Works like a champ!
It’s frightening how these razors collect so much hair over the years. I used a shop vac to suck out most of the micro follicles. Ewwwww!
