Q: How are voltage and current related to battery life? What is the
Physicist: Chemical batteries use a pair of chemical reactions to move charges from one terminal to the other with a fixed voltage, usually 1.5 volts for most batteries you can buy in the store (although there are other kinds of batteries).The chemicals in a battery litterally strip charge away from one terminal and deposite charge on the other. In general, the more surface
Connecting a super capacitor to the solar battery in parallel
Putting a large supercap in parallel with the battery does not change the terminal characteristics. You still would have low voltage trips at 10.5V, and still classify as fully charged at 13.4V. The charge stored in a capacitor is: W = 1/2 * C * V^2. For a capacitor in parallel with a 12V battery the total charge in the capacitor would be:
