Car Battery, they say you are lead acid battery
When people think about lead acid battery, they usually think about a car battery. These are starting batteries. They deliver a short burst of high power to start the engine.
There also are deep-cycle batteries. You’d find these on boats or campers, where they’re used to power accessories like trolling motors, winches or lights. They deliver a lower, steady level of power for a much longer time than a starting battery.
Lead-acid batteries are used for a vast number of purposes, but all batteries provide either starting or deep cycle power. The only difference is how much power is delivered and how long it needs to be delivered.
Originally invented in 1859 by a French physicist, they have been used for a power source in machines and vehicles and have evolved somewhat with time. Inexpensive and able to supply the surge required to start an engine, they have a very low energy-to-weight ratio but a decent energy-to-volume ratio. What does that mean? It means that per pound, they aren’t so hot but per-square-inch, they perform fairly well. To be more energy efficient, it is necessary to increase viability for the energy-to-weight ratio as well.
A lead-acid battery stores electricity through a reverse chemical reaction. This occurs when two dissimilar materials (positive and negative plates) are immersed in the electrolyte, a solution of sulfuric acid and water. Batteries operate in constant cycles of discharging and charging. When a battery is connected to a load that needs electricity, such as your car, it discharges. If you’re driving your car without accessories, the alternator charges the battery by adding current.
Flooded lead-acid batteries immerse the energy-producing electrodes in liquid electrolytes and release gases upon charging, the most common example being a standard 12 volt car battery. Absorbed glass mat (AGM) batteries create energy by immobilizing electrolytes with a micro fiber glass mat. Gel cell batteries use fumed silica in the electrolyte, which hardens into a gel. Drying of the gel during charges causes a loss of performance in this particular lead-battery.
