OK -I hit the part about Lithiums not leaking because of dry chemistry awhile back -that was immediately followed by the sound of me beatin feet for the big box store and spendin 30 bucks on AA's and AAA for my remotes -will now follow this thread for awhile to see if a consensus develops in favor of particular charger/rechargeable Lithium battery. I keep original remotes around for easier programing of oddball features and use my semi-smart multi-device remotes for day to day use. This has caught me with dead and leaking alkaline's a number of times over the years. Care less with a remote if the battery goes just plain dead - but really don't want it leaking.
