Batteries are rated for a limited lifespan, also known as their shelf life. The Battery Bank estimates most batteries have a shelf life of "about 7 to 10 years."
Energizer estimates their basic MAX and Advanced Lithium batteries last up to 10 years, while their Ultimate Lithium batteries are still usable for 15 years. Their Rechargeable line has a limited shelf life, losing "1% of deliverable energy per day."
Energizer suggest the following tips to extend the battery life:
Contrary to popular belief, Duracell suggests not to refrigerate batteries to extend their lifespan.
Store batteries in a dry place at normal room temperature. Most Duracell
batteries will provide dependable long life even after five years of
storage in these conditions. Do not refrigerate Duracell batteries, this
will not make them last longer.
When buying batteries, try to find the manufactured date to determine how much life is left. Sometimes the date is printed on the label or an expiration date is provided. It's always a good idea to check online reviews to see if a particular seller struggles with quality control. Oftentimes, a rock bottom sales price can be attached to battery stock nearing an expiration date. Exercise some caution when buying batteries and don't be left dead in the water with no juice on a supposedly fresh battery!
