As water is consumed, the electrolyte concentration increases and the electrolyte level in the battery drops with the loss of water volume. Eventually it falls below the top of the electrodes exposing them to oxygen from the atmosphere and charging gasses.

Does storing batteries in freezer work?

A number of studies have shown that storing batteries in the freezer helps them retain their charge longer. … Alkaline batteries stored at “room temperature” self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount.

How do you know when rechargeable batteries are dead?

Yes – just check the cell voltage. NiMH are fully discharged at ~1V, so if any of your cells are going down to this quickly (after a few cycles) then they’re dead. For cycling batteries you don’t need to fully discharge.
