Charging Oculus Quest 2 headsets is as simple as plugging in a cable, but the controllers use removable AA batteries to provide power. This means there’s no direct way of recharging the controllers, but workarounds do exist if you need them.
One of the reasons Meta decided to forego an internal rechargeable battery is simple the Quest’s controllers use very little power. Using disposable alkaline batteries, their battery life is measured in months.
This reduces or eliminates the need for controller battery charging unless you’re a truly heavy user of VR. Even then, you may never run into this issue. The folks over at Upload VR, who we assume use VR more than most people, only had to change controller batteries after three months! The most frequently people have to change batteries seems to be to be around the one-month mark. That’s serious battery endurance.
Considering how long Quest 2 controller batteries last, the simplest strategy is to buy spare disposable AA batteries and keep them on hand when your current batteries run out of power. It’s faster than recharging them anyway and you’ll be back to beating those sabers in no time.
There’s definitely an environmental argument to be made for using rechargeables, but honestly, the Quest 2 controllers need a battery swap so infrequently that it doesn’t really make much of a difference. Especially since alkaline batteries are safe to dispose of. Still, you will be reducing your waste by using rechargeable alternatives.
As long as they aren’t connected and left in their packaging, alkaline batteries have a long shelf life. Check the expiration date and put a pack in a drawer somewhere for the day you need them. Whether in a controller or another device.
