Why do batteries lose charge when they’re not being used?
In: 2655
Depends on the battery.
A chemical cell like a AA, yeah, it dies over time as the chemicals in them still react. A Lead Acid battery on the other hand will actually charge itself over time. Back in college, car wouldn’t, dead battery start due to lights on, but I didn’t need it. I could walk to school. 3 days later, car started. If the battery died due to a short circuit or a dead cell, then the lead acid is toast, but this was just ran down.
