Most of my smoke detectors take 9 volt batteries. They now have lithium rechargeable batteries in them. I have other handheld devices that also use 9 volt batteries and they are getting lithium rechargeable batteries in them for now on. No problems at all. Good for the planet and good for me. I can recharge hundreds of times, nice going EBL.
