The basic theory of 12v battery charger



The basic theory of a 12v battery charger is a tutorial addressed to the people in need how a how to make 12v battery charger at home

we have to know the process in order to make it ,after knowing the basic theory and the working process of a lead acid 12v battery we can build assemble or make a 12 volt battery charger with protection. The 12v battery is still in demand these days altho the lithium battery technology is fighting back, but till 18650 battery will win we still have to use lead-acid battery because there are more affordable at this point.As well as starting the engine, an SLI battery supplies the extra power necessary when the vehicle’s electrical requirements exceed the supply from the charging system. It is also a stabilizer, evening out potentially damaging voltage spikes.[2] While the engine is running, most of the power is provided by the alternator, which includes a voltage regulator to keep the output between 13.5 and 14.5 V.[3] Modern SLI batteries are lead-acid type, using six series-connected cells to provide a nominal 12 volt system (in most passenger vehicles and light trucks), or twelve cells for a 24 volt system in heavy trucks or earth-moving equipment, for example.
