11.5: Batteries
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

How Lead Acid Batteries Work
An atom has a neutral charge when it has the same number of protons and electrons because the protons are positively charged and the electrons are negatively charged so they balance out. If the atom has more electrons than protons then it''s a negative ion. If the atom has more protons than electrons, then the positive ion. How It …
Complete Guide on How to Charge a Lead Acid Battery
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.
