He means having to plug the controllers in instead of being able to swap the battery. That in itself was a problem because AA batteries aren't actually a standard size, so you'd either get brownouts when swinging the controller, and/or find the battery difficult to remove without damaging it. It was common to 'cope' by jamming foil and other things in the spring or compartment. The covers would partially slide off a lot in actual games because they were only magnetic.

If the Rift were released now, it would be shit on relentlessly, but it is remembered fondly because it was the first headset of many and allowed easy gestures in VRchat.
