ELI5: Why do batteries lose charge when they''re not being used?
The charge exists because electrons are located in compounds or elements where they are not the most thermodynamically stable location, meaning that we get energy from batteries in the first place by giving those electrons a route (through the outside of the battery) to exchange locations from the less stable circumstance to the more stable circumstance.
Lead Acid Batteries: Do They Store AC or DC Power for Car Usage?

Why Can''t We Store AC in Batteries instead of DC?
Why AC Can''t be Stored in Batteries like DC? We cannot store AC in batteries because AC changes their polarity up to 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second.Therefore the battery terminals keep changing i.e. Positive (+ve) becomes Negative (-Ve) and vice versa, but the battery cannot change their terminals with the same speed so

6 Frequently Asked Questions about “Batteries store electrical charge don t they ”
Do batteries store electrical energy?
There are no batteries that actually store electrical energy; all batteries store energy in some other form. Even within this restrictive definition, there are many possible chemical combinations that can store electrical energy--a list too long to go into in this short explanation.
What is a battery and how does it work?
A battery for the purposes of this explanation will be a device that can store energy in a chemical form and convert that stored chemical energy into electrical energy when needed. These are the most common batteries, the ones with the familiar cylindrical shape.
What happens if a battery stops working?
Batteries are stores of chemical energy. When being used in portable electrical devices like your phone, they transfer chemical energy into electrical energy. When a battery stops working, it is because the chemicals in it have been used up.
