12V Lead Acid Battery Charger(Homemade)

I took a MOT and carefully stripped out the 2000V Secondary and replaced it with a low voltage high current winding of 18-20T or 12ga wire. New fully rectified DC output is 15.8VDC. An electrolytic capacitor of 1500uf was also added for smoothing purposes(Not much smoothing is required for charging lead acid batteries). Also includes a voltage monitoring circuit which allows you to know when the voltage of the battery being charged has reached completion. A green LED will be brightly illuminated to let you know to unplug the charger.

Schematic Here:

The circuit in the schematic above will connect to this automatic charging cut-off circuit, then to the battery to be charged:

Incredible how to make 12v lead acid battery charger!

Incredible how to make 12v lead acid battery charger very easy https://youtu.be/eme0oRNlE3o just need a laptop charger rated 19v and some amps in the video it is an HP laptop charger rated DC 19v |2.31A but to stay on the safe side you should consider just half of that power.And the secret component is an auto bulb rated at 12v 5W.In this configuration the battery is charged with 0.26A so is very safe but watch the bulb it can get hot, to increase the output you can change the bulb with a 10W same auto filament bulb and you gonna have 0.45A, if you want more try with 20w bulb you should get approx 1A.This can be considered 12v battery hack because is not a normal 12v battery charger.
Or if you buy a cheap and good small 12v battery charger http://amzn.to/2i9zfpM it does the job for the price

Cut-Off Circuit For 12V Lead Acid Battery Charging

If you are looking for a simple but effective Lead Acid battery charger cut-off circuit, then look no further. You can use this circuit in conjunction with any battery charger(except capacitive types) which do not have an automatic shut-off once the battery voltage has climbed to 14.2V(You can adjust this value with the zeners). You can modify the circuit to charge 6V lead acid batteries instead of 12V as shown in this video. Just replace the relay coil with a 6V type, use a lower voltage power supply (8-12VDC Open Circuit), replace the 12v zener leading to the base of the NPN with a 6V or 6.2V, along with the same (2) 1n4001’s in series, replace the 12V zener to the relay coil with a 6/6.2V zener, and cut the value of the LED resistor in half.

How to make a 12 Volt car battery charger

Tips and tricks about how to make such a circuit. Be careful with car batteries and other batteries like: Ni-Cad, Ni-MH, Lithium polymer. their energy content is huge, so don’t mishandle or shortcut them and always uses suitable fuses to prevent burn,scorch,fire. Make no electric sparks around a car battery, an open car battery produces H2 and O2, if the battery is not vented and this gas “hangs” around it, it can explode, this explosion can even go into the cell, the plasic battery can burst open in that case. The circuit is only (!) usable for a lead acid (open or closed) battery. Don’t charge Lithium polymer cells with this charger (!!, dangerous).

You can find the links to all my video’s about electronics (in thematical order) on my Channel Trailer “Radiofun232 on Youtube”. Link https://youtu.be/xbgQ8T3oqh4 . (all info in the “comments” section). My books are available on the Lulu website, search for author Ko Tilman.

Sealed lead acid battery charging – requested

Please read! YouTube user Ciprianwiner wanted to know more about what I use to charge my sealed lead acid battery, so here it is.


The charger is a Numax 1 amp 12v sealed lead acid battery charger. I paid around £20 for it from a local battery specialist (Manbat) where as it would usually cost £35 on-line.

I am not saying that you never charge a sealed lead acid type with a car battery charger but I would advise being careful or using some sort of current limiting as once you have a gassing sealed battery from too much charging current its pretty much downhill from there in terms of capacity.

Usually you can find datasheets online from the battery manufacturers website with all of the charging specs for your specific battery.

Also it is common to see the battery’s voltage read well into the 13v range when it is taken off charge (I have even seen as high as 13.6v stay for a while!). But once you put a load on them it will come back down.

Quite a dull and boring video really!

Lead Acid Battery Charging Stages

How does a battery charger or charge controller recharge a lead acid battery? Here is the simple explanation.

In this video, I will describe the 3 stages of charging a lead acid battery as well as the equalization process. We get spoiled by advanced battery chargers nowadays but it still very beneficial to understand how it works and how to tweak the settings of your charger based upon the specific recommendations of the manufacturer.
