Review on 🔋 HQRP 2-Pack Gumstick Battery Compatible with Sony NC-5WM, NC-6WM, WM-701C & More - Long-lasting Power for Multiple Sony Devices by Tommy Abreu

I received these for use in a Sony wm-ex633 Walkman. These batteries should work with all EX series cassette players and they worked in my case. Finding an original charger or stick battery charger is difficult and expensive, but you can just use any universal charger with an adjustable negative terminal and charger. to C or D batteries I have the one often bought with these Revain recommended batteries. The thing about new old stock or used stick batteries that you can find used is that they are known to not hold a charge for long at all. This may seem like cheap quality to some people but they are definitely reliable and one of the few sources of these batteries still in production today so I'm glad I was able to find them. And as said, there is no need to buy a special charger for them. A universal charger that can charge NiMH batteries and is long enough for them will help even if they claim to only support cylindrical batteries.
