4 Storage technologies

[Skvez]

what about buying the acid now and storing it. then just pour the old acid out the old battery and pouring the new acid in.
would that work ?

unfortunately not, the plates degrade too.

Probably the best action is to buy 'wet' batteries (VRLA) dry, needing the addition of distilled water to activate them. Store these as air tight and dry as possible and store distilled water to activate them when the times comes.
Still that's only storing batteries not making new ones and so they'll run out eventually.
