Why do rechargeable batteries eventually lose their ability to be recharged?

But according to research by the U.S. Department of Energy, the reason lithium-ion batteries lose their charge over time is because of an undesirable chemical reaction. … The more cycles you charge, the more crystals are formed, and the more efficiency and capacity you lose.

How do you know if a battery is rechargeable?

Measure the voltage. If they are 1.5V then they are non-rechargeable. If they’re 1.2V then they are rechargeable. If they have a metallic case with (from memory) yellow/green and black, they’re normal batteries.
