Since remotes don’t consume a lot of juice, I usually will put the non rechargeable batteries in the charger for like 5 minutes, while monitoring them for temperature or anything out of the ordinary. That usually gives the remote a whole month worth of energy (granted, we don’t use it much).
Never try this if you’re prone to being distracted and forgetting them in there though, that’s recipe for a fire.
Well that is not what I experienced, so I won’t.
