Thank you for all your video
All the best mate !!!!!

Hi,thanks for your tips!That kind of battery could be used for motorbike isn't?Thanks Bhai 🙏

Will 20v 2.5a work?

I have a 12v 4.5ah lead acid sealed battery it's for a Bluetooth speaker .I charge it with an adjustable power supply at 12.8v to 12.6v and it goes dead after one song..anyone know how I can charge this so it will work for a few hours at least

Charge power plzzz
Volt and Amper

Music/noise NOT required!

MY BATTERIES
YUASA NPW36-12
12V 36W

IN REGULAR FASHION, can i use Solar Charge Controller +24v DC Power Adapter for charging 12v7ah battery ?

but it getting hot without diode. power adapter was rated at 24vdc 3amps.

but as per digital multimeter its giving only 0.3-0.4 Amps .

now i have connected 10Amps diode to the 24v+ wire. Still its' not charging . Initially it charged upto 13.1 Voltage FROM FRESH Battery voltage of 12.5 .

But Now , when i installed Diode, still it's saying 13.1-13.2-13.1, whats the solution ?

Either i go and buy Another Laptop power adapter of 15v.(bcoz i think, that i've shorted/damaged the 24v adapter
without diode use)

PLEASE HELP.. PLEASE HELP...

Hello Everyone. I have a question. I have a B&D 750W 6.52amps inverter model PI750AB. For the most part it works perfectly. But I'm experimenting with using it with a smaller battery in my chicken coops when needed. I have it hooked up to a GT12080-HG 12v 8ah battery. I can run a fan, laptop radio etc no problem. But when I plug in a 200w heat lamp the inverter goes yellow and cuts the power. The battery is fully charged. Why is a 750watt inverter shutting down when plugging in a 200watt heat lamp??? Any ideas?

Can I use my laptop recharger

Wasting time . Throw it away and by a new 1

If the loptop charger is already 12v do i still need a lightbulb?

how much voltage needed to charge ups battery alone??

Can we use other any water

Hi brother ru sure we can charge the ups battery by using a laptop charger 🔌?

Can i use 15volts and 5amperes in 12v and 7amperes battery?

great idea Thanks genius

What is a “wolts”?

i suppose you could try this as a last resort to tossing it, but first charging the battery is current limited up to about 14 volts, then voltage is held and current is tapered off to somewhere around 1/4 amp and is then terminated or held in float mode at around 13.4 volts (above is ballpark and is dependent on actual battery). Also these are agm batteries and should not have enough water in them to spill. If you tip it upside down and it leaks, you have too much water. The vent caps are not supposed to be opened, But like i said if your going to toss it out then sure try to revive and water it, just be careful.

This is fake

Bro I try it's work thanks soo much 👍👍

I think DC charging sulphates, and AC charging desulphates.

How did you make the charger? How’d you connect positive and negative

1 questions,
When you use the laptop charger, how you now when the charger will stop charging the battery to avoid continuously Charging that might explode the battery. Is using laptop charger will have cut off system during charging?

can i charge a dry 12 v battery like that as well ?
