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. 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. 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.

Thanks one again DIY Electronics rullez !!!
Hello friendz i will back with a new video in which i am going to make 12V DC supply from 220V AC supply
Generally we see 12V DC supply in our little or smart Home🏠🏡 appliance such as Mobile Charger,Laptop Adapter, or we can else say digital electronic Devices
So, How this adapter or charge convert 220V AC to 12V DC Supply Let see:
I am just making this DC Supply which also run these same appliances………..🔝⬆⬆🔺
I hope you like

The IC-7000 – 7 AMP 12-24V Intelligent Microprocessor Battery Charger is capable of testing, charging, maintaining, and even repairing all types of 12V and 24V lead-acid batteries, including WET (Flooded), GEL, MF (Maintenance-Free), EFB (Enhanced Flooded Battery), AGM (Absorbed Glass Mat), and 12V Lithium and AGM+ batteries. It has a built-in intelligent microprocessor which makes charging faster, easier, and safer to use. Safety features include spark proof, reverse polarity, short circuit, over current, overcharge and overheat protection. Keep it connected 24/7 without damaging the battery and keep your battery ready to use.
Smarter™ Battery Chargers offer expanded features not found on most chargers. Restorative functions like desulphation, destratification, and optimization allow you to regain 100% of your battery’s capacity. These chargers are so advanced, they have the capability to recover battery voltages that are too low for traditional chargers to detect.
The Smarter™ 7A 12V/24V Battery Charger charges batteries from 14-230Ah (12V) and 14-115Ah (24V) and safely maintains 6V and 12V lead-acid batteries of all sizes.
With a dedicated Repair Mode for deeply stratified or sulphated batteries, the Smarter™ 7A 6V/12V Battery Charger could save an otherwise “dead” battery.
The charger also has a 13.6V 5A Supply Mode which allows you to power 12VDC devices.

In this video, I will show you how easy it can be to design your own Automatic 12V Lead Acid Battery Charger Circuit Board and have them manufactured professionally at https://jlcpcb.com JLCPCB is the largest PCB prototype enterprise in China and a high-tech manufacturer specializing in quick PCB prototype and small-batch PCB production.
You can use this circuit to charge12V 1A ~ 12V 7A Battery.
List of Components:
R1,R3 = 1K https://goo.gl/4XW5DR
R4,R5 = 1.5K https://goo.gl/V1jUMS
R6 = 10K https://goo.gl/RVB6fy
R7 = 1.2K https://goo.gl/7pZQ96
R2 = 1R5W https://goo.gl/Yq1ouh
PR1 = 50K https://goo.gl/S94qgc
Q1 = D882 https://goo.gl/VbDHWe
D1 = 1N4732A https://goo.gl/2hcQtB
D2,D3,D4 = 1N4007 https://goo.gl/CqfNDo
Relay = 12V https://goo.gl/t87Jg3
U1 = LM7815
5MM LED = Red,Green,Blue,Yellow
Alligator Clips = 2
Jumper = 1 https://goo.gl/1xS713
I designed this circuit to charge your battery @ 70% to 75% only due to some safety reasons. If you want to make it for 100% charging, then remove the LM7815 and connect directly 18VDC supply and set tripping point at 15.8 ~ 16V. and always use 5 to 6 times lower charging current from the maximum value of battery current. i.e 1.2A for a 7AH battery.
*This circuit Has not any current limiting feature.(except 1R5W Resistor)
**This circuit is not 100% Perfect, but it is still very useful for hobby/DIY projects.
***Make it at your own risk.
