Recharging: After the cell is discharged, it is charged again by connecting it to a DC source. This process is
similar to the charging process and the same chemical reactions take place in it, which take place in the charging
process. In this process, due to the formation of sulphuric acid (H SO ), the relative density of the electrolyte

increases.
Battery (accumulator) capacity and rating, booster starting, IBS (Intelligent Battery System) system.
Introduction: Battery has an important part for vehicles. It provides electricity to self-starter for starting engine,
it used to light headlights while travelling in the nights and vehicles other parts get electricity from it such as side
indicators, radio-heater and wind screen wiper. Battery sends to controlled voltage to vehicles electrical parts. In
petrol engine ignition system work by the current of the electricity sent by stores chemical energy. When a battery
circuit is started or bulbs switches on, the stored chemical energy turns into electrical energy and starts going into
that circuit through the wires.

Battery capacity and rating: Battery capacity refers to the amount of energy stored in a battery, typically
measured in ampere-hours (Ah) or mill ampere-hours (mAh). Battery rating, on the other hand, often refers to the
performance or quality of battery, which can include factors like longevity, efficiency and reliability.

The SOC (State of Charge) voltage chart give is you an indicative state of charge based on the battery voltage
when the battery has been at rest for 30 minutes, this means no charging or loads in the past 30 minutes.
These should be compared to your SOC battery monitor and the battery monitor should read a given chart, if
it does not then usually the battery, monitor needs adjustments, the SOC chart in most cases will be far from
accurate.

But we should need always check these setting in your Battery monitor, we to some identify for battery rating here
following these chart:
SOC for lead Acid battery, when at rest for 30 minutes.

Note: Voltage and state of charge (SOC) will vary with Temperature and Battery Type AGM batteries
will read about 0.15 volts HIGHER than wet cell batteries.
