Based on the description on their site, the controller includes a built-in battery: "8.39 Wh Li-ion battery, 35+ hours of gameplay… "
That was disappointing for me. Specially condidering the Steam Frame’s controllers make use of AA batteries: “One replaceable AA battery per controller, 40hr battery life”
AA Batteries might not be as convenient to use, but being able to replace them is a great advantage. All my Xbox360 controllers still work fine, but none of my PS3’ Dualshock 3s.
The official docking station could be used to recharge (rechargables) AA batteries so the functionality could remain the same.


Non-rechargeable batteries is a terrible idea from an ecological point of view. Also, Steam have made considerable effort to make the Steam Deck repairable. I hope they do this with all their new hardware, so replacing the battery won’t be a big hassle.
You can buy rechargeable AA and AAA batteries
Outside of specialized uses like wanting a very long shelf life for rarely-used devices, I kind of thought that everyone had switched to rechargeable AA and AAA batteries years back.
I get people even here who just swear up and down it’s impooooooosible for them to switch for a littany of excuses. It costs too much (it doesn’t, it’s actually way cheaper), why would I put them in a remote? (Literally why wouldn’t you) They aren’t as convenient (compared to buying them at a store?). Or my favorite “they don’t work as well” ,which they don’t in maybe 5% of cases. So they could still replace 95% of their alkaline but let’s be real they just don’t want to even try.
They’re still there, and usually it’s pure laziness, or just arrogance that they don’t care about the immense waste.
I mean, there are some legitimate reasons.
Non-rechargeable alkalines do have very low self-discharge rate, so they work well if you’re gonna stash a flashlight somewhere for a long time for emergencies.
The voltage on different types of batteries is not the same, and there are some devices with power supplies that cannot handle a wide-enough voltage range. I have a Grundig G6 shortwave radio, for example, which will not run on NiMH AA batteries (1.2V, rather than 1.5V alkalines or lithium). I suppose that I could get rechargeable lithium-ions, but I don’t really want to deal with rechargeables with different battery chemistry floating around, and my current battery charger can’t handle lithiums.
I just remember the 1980s, where the norm was alkaline, and people had to buy the things all the time for all kinds of battery-powered devices. Was nice to be able to just recharge batteries at home.
Kids toys are another use case for non rechargeable. I’m not going to buy a 100 pack of rechargeable batteries.
Jesus, this has to be one of the dumbest comments I’ve seen on this site
If you think parents are putting rechargeable batteries in all their kids toys then you are the dumb one.
I absolutely am doing that. I don’t think it’s dumb.
Um, I use rechargeable batteries in all my kid’s toys? With how often they need to be replaced, these batteries have already long paid for themselves.
You can get 8 rechargeable AA’s from amazon for $12, or $1.44 each. Non-rechargeables are $0.78 each. If a rechargeable battery prevents you from having to buy a second set of non-rechargeables then it’s paid for itself.
If you want, you can just put rechargeable batteries in their most commonly used toys. Or better yet, teach your kids how to replace the and charge the batteries themselves. A 4 or 5 year old should be able to handle that without issue. And it means you aren’t doing everything for your kids, which means they learn some self-sufficiency
Yeah but so many people wouldn’t.
Rechargeable AA batteries are a thing. From an ecological point of view, the custom battery is a bigger problem. In 20 years the controller will still work and AA batteries will still be available, but no one will be making new built-in rechargeable battery replacements (even if Valve originally intended for the battery to be replaceable).
One of my favourite controllers has been the Dual shock controller. I’ve got 2 PS3 controllers that I love using. Their rechargeable batteries are shot to shit. I would be much happier if I could use AA.
If the device has a 40 hour battery life and the battery lasts 1000 cycles, that will give you 40.000 hours. That means you can play for five hours every day for over 16 years. I don’t think many devices will last longer than that.
Batteries still wear out because of age regardless of how many charge cycles they’ve had.
Most people won’t replace an internal battery. If the battery dies, they buy a new controller.
I’m not sure whether this is actually better for the environment than even if they were using non-rechargeables.
