I have converted to Lithium cells in most everything that gets light but regular use. Yes, they are stupid expensive but I have a few remotes that have had them for over 10 years now. I keep several LED flashlights handy with a couple that only have Lithium cells. Few things are as worrisome as having a power outage and finding out your flashlight is dead. I use rechargeables along with a smart charger for most everything else just for environmental reasons. However, if needed,the rechargeable don’t perform as well as most standard new batteries in my experience. Nothing has the shelf life of Lithium’s.
