snip but I have had just the opposite experience. comment I have had the same experience as Frank.  I have had many Duracell alkaline batteries leak on me when they are within their good until date and haven't been left dead in the item.  FOr the last several years I have used Energizer, Sam's club brand and Ray o Vac and haven't had one leak.  I once tried to get Duracell replace a flashlight that was ruined and was told I needed the original receipt and it did not matter what the good until date was on the battery.   Ref the lithium cells I note that they have a higher initial voltage (1.75+)than an alkaline battery and some devices will not function with them.  I have a couple battery powered clocks that require a ladder to get to to change the battery and I put the lithium cells in them and neither would run with them.  They ran fine when I put alkaline in them.  So then, to use them I put them in my house thermostats and one worked fine with them and two would not but again ran fine with alkaline cells.   You can see their characteristics at the following site.  https://data.energizer.com/pdfs/l91.pdf  Their advantage over alkaline cells varies significantly depending upon their discharge rates.  Their cost is only justified at the higher discharge rates, or at very low temperatures where their performance is much better than an alkaline.
