Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.

Best case scenario, the average shelf-life of vitamins is two years, Davis-Cadogan adds. There are some vitamins that come with special storage instructions, so it’s important to thoroughly read ...
An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.
Typical self-discharge or shelf life Lithium metal: No: 10 years shelf life [3] Alkaline: No: 5 years shelf life [3] Zinc–carbon: No: 2–3 years shelf life [3] Thionyl chloride: No: 1% per year [4] Lithium-ion: Yes: 2–3% per month; [3] ca. 4% p.m. [5] Lithium-polymer: Yes ~5% per month [6] [better source needed] Low self-discharge NiMH ...
Service life of several thousand hours (continuous operation) [9] Shelf stable over several years (retaining 90% of initial capacity) [10] Silver oxide cells are a primary battery and do not have a cycle life or a rate of charging and discharging. [2] Typical silver oxide cells are stable at temperatures below 100°C, at which point leakage can ...
However, this process may reduce the shelf life of the battery. [citation needed] If treated well, a Ni–Cd battery can last for 1,000 cycles or more before its capacity drops below half its original capacity. Many home chargers claim to be "smart chargers" which will shut down and not damage the battery, but this seems to be a common problem.
