12V DC Supply or Battery charger(using full bridge)

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………..🔝⬆⬆🔺

Nikola Tesla 12-Volt 4-Battery charger circuit impossible? DIY

Nikola Tesla 12-Volt 4-Battery charger circuit impossible? Nikola Tesla demonstrates this with his “4-battery switch” system where he chooses to use four identical batteries to implement this circuit. The current flowing through the bulb can be arranged to be a charging current for another battery. It can both light the bulb and charge another battery without needing any extra current. And now, the newly charged battery 2 lights the bulb and charges up battery 3 again. Seem impossible? Well it isn’t!

Bosch Battery Chargers

This video provides an overview of the various battery chargers that Bosch provides for a variety of commonly used battery applications, including passenger cars, commercial vehicles and leisure applications.


DIY Battery Charger Installation – CTEK 4.3 – On Ferrari F430 (m)

DIY Battery Charger Installation – CTEK 4.3 – On F430 (same procedure for 360)

Ferraris and all other vehicles using lead acid batteries really hate to sit unused. It will lead to premature battery failure and sometimes an unusable car, usually when you want to use it.

Install a trickle charger to both maintain proper charge and periodically run the lead acid battery through charging cycles. I have selected the CTEK 4.3, but better chargers are released periodically. My previous favorite was the CTEK 3300.

CTEK 4.3: (*The CTEK 4.3 is also known as CTEK 56-864 I believe)
$59 amazon prime : http://www.amazon.com/CTEK-56-864-Ba…words=ctek+4.3
$55 at http://www.techbatterysolutions.com/…c7827_a_7cC002

Total Time:
12 minutes (while filming video, taking pictures, and drinking Old Engine Oil)

Difficulty Level:
2 (scale 1-10)

10mm wrench. Preferably an insulated handle wrench so you don’t short out the battery accidentally.

1. Remove passenger footwell (2x philips head screws)
2. Remove negative 10mm terminal post. I did not remove the entire terminal because then I would need my radio code and the cars ECUs would need to re-learn.
3. Install negative (black) CTEK lead to negative battery terminal.
4. Install positive (red) CTEK lead to positive 12v battery terminal.
5. Zip tie pigtail leads to something solid to stress relieve terminals
6. Replace passenger footwell.
7. Test charger.

Old Lucas Mechanical Voltage Regulator – For Old Tractor Dynamo Battery Charging

I found this with a bunch of old tractor bits in my grandmas woods when I was hunting! It looked like a 4 cylinder diesel tractor. This would have regulated the voltage coming from the dynamo. This tractor was probably made before 1960 because around the 1960’s they stopped using dynamos in cars and started using alternators. So this regulator is at least 50 years old.
