I jumped on the eneloop band-wagon after hearing about them for years, and I'm not impressed honestly. I was expecting like Wii U Pro Controller or at the very least Switch Pro Controller battery life but that's not the case at all.
I get annoyed having to swap out the batteries in the Xbox controller I'm currently using to swap with my one I have synced with my laptop and then put those into a charger. So to get around this I would have to buy another set of these expensive ass batteries.
I have no idea how so many of you have issues with your built in rechargeable batteries in your controllers. I've had my PS4 and Switch Pro Controllers since 2017 and I've never had a problem with keeping charge. The problem was with the analogs if anything.
If I wanted all of my gaming controllers to always have batteries in them to play whenever It'll cost a fortune in just purchasing the eneloops or rechargeable AA's. So instead I have to play this stupid game of constantly switching batteries between controllers and that shit is annoying. I just rather have built in rechargeable batteries, never been an issue before if they were well made (I had a set of third party Xbox Battery packs that shit the bed after a few months).
I paid around $40 for just 4 batteries and the charger for the eneloop Pros. If I wanted coverage for just two more of my controllers It's another $32 for just 4 more, and that would just cover having one set in place for one of my Switch controllers and one for my extra Series X controller. Shit gets expensive really quickly. I'm honestly fine dealing with built in rechargeables, it's way more convenient and I can just charge them daily and they're fine.
