Battery ....

Basic
Lead Acid Battery is made from plates, lead and lead oxides [for some density, hardness, etc.] with 35% sulfuric acid and 65% water mixture. This combination of acid water is called electrolyte which produces electrons in chemical reaction. For the battery test, the amount of sulfuric acid in the electrolyte with the hydrometer is measured.

Type
Basically two types of battery are seen,

Deep Bicycle:
This type of battery is called Marine Type Battery, which is often capable of charging discharge, it is usually such that the specification is written in such a way that 12V7AH battery, ie it is 12 volts and can be able to carry 7 MPAs per hour or 1 hour for 7 MPEs. These contain plump plates that hold the charge for long periods of time and are able to discharge gradually.

Starting battery or cranking battery:
These are basically the car battery. To start the car or engine is a very strong start-up motor [which is called self-contained, it starts with 15-30 seconds, then the engine starts to take the start, that means the speed of 25-150 MPavers is very short-lived, after that the cell is running and the battery is low No work of energy, but the battery is recharged from the engine's alternator. They contain thin plates which can make a lot of current or MPaire.

Lid acid battery type 2: Deep bicycle and car battery. Plates are thin in the car's battery , so that the surface current is high. On the other hand thick plate is used to provide long battery power to the Deep Bike batteries.

IPS uses Deep Cycle Battery. This battery is a rechargable battery; It is often charged and discharged .

On the other hand, the car's battery starts for a short time (30 seconds) high ampere (30-100 amperes ) standard power; After that the car's alternator car controls the power of the vehicle. At the same time, charging the battery of the car, again to start the high-end engine, the car could serve 20% of its energy for more than one year.

CCA
CA
AH
RC (Risphi Capacity) is the amount of current in a battery meant to be present and is calculated in minutes. And the C Measurement method is that the battery can be supplied with a charge of 25 AH at a constant angle of 25 AH from a full charge battery.
Charging
Battery needs electricity for charging.
