thanks for the explanation. I learnt that volt is controlled by source and amp is controlled by the device. In case of battery chargers, how does the source (charger) defines/controls the amp it is charging at?
@@ramcholan2034 I believe it’s done by the resistance and voltage of the battery. As the battery gains voltage it doesn’t require as many amps of power to recharge it. Bad batteries draw more amps and they don’t reduce the amperage from the charger because the voltage won’t increase.
hey brother thanks so much for the quick lesson there. I certainly appreciate people that make sense when they are making videos for public. keep up the good work.
there around 4:57 you mention that if the 2 leads touch, it could short out the 2 clamps. Can you explain more about that. Would that ruin the charger if it is set at 12v 2 amps and they touched for 1 to 2 seconds , probably 1 second ? I have a reason why I would actually like to do that, IF it won't ruin my charger.
I can’t really say because there are so many different manufactures of the battery chargers. However, even though I’ve been using them over 50 years, I always go to great links to make sure I hooked to the battery before I ever plug the charger in. as many goofy things I’ve done in my life, touching hot things together, I feel my battery charger is worth more than seeing a spark come off the clamp.
@@MrHardware1 Can a completely dead battery be recharged? For a completely dead battery, your best bet is to let it charge overnight at low amperage to prevent any additional stress to the battery's cells. You can rush it, but the risk of causing long-term damage to the battery is much higher. 5amp no good best 2amps will not damage the battery.
@@MrHardware1 Is it better to slow charge or fast charge? When using slow charging, the cycle life of the battery can usually reach more than 3,000 times. However, if it is always fast charging, the cycle life will be shortened to about a thousand times, or even lower. So slow charging vs fast charging are important to batteries life.Sep 14, 2023
If it’s a lead acid battery similar to what was in the video low amps put a better charge opposed to charging with high amps. So I would use the two amp setting if I was using the charger in the video.
You must check to see if the battery needs water before charging unless it is maintenance free. If battery needs water...that is why it is dead. Add ONLY distilled water to the upper part of each cell and charge with fill caps off.
Checking a battery's liquid level, and topping off with distilled water if necessary, is critically important. It is not hard to do, but many folks don't know their vehicle's battery has a fluid level that needs occasional checking. Im curious why you say to charge the battery with the caps off after topping off with water though. I've always just add enough distilled water to cover the plates and put the caps back on. I'd be concerned leaving them off any longer then needed since accidentally kicking one over and spilling battery acid everywhere is super not fun... Done it dozens and dozens of times now and never had any issues charging with caps on. Well I did have one swell up and blow the cap off one side, but pretty certain my charger going haywire was to blame. Put the multimeter on it and discovered a few amps at 16.5 volts had been boiling the poor thing for the past hour. So that charger went immediately into the trash, and thankfully haven't any problems like that one since...
Storing my car for 6 months. Going the use a trickle float charger. Best to keep the battery hooked up to the car? Red to positive terminal and black to terminal or unpainted steel? Or best to take battery out and put both clamps onto the terminals?
Hello, why is my smart charger 15-2 amps only charging at .4 amps? I've connected to 2 different batteries and it still only charges at .4 amps?

@@tableshaper4076 it’s very hard to say from here however, either your battery is fully charged or possibly it’s dead or has a dead cell and it won’t allow very much to flow through it.
@@MrHardware1 Thanks for the response. I left it on overnight and it was actually working. It showed no response (.4amps) from 8am to 9pm but this morning it was 90% charged and up to 6amps. I just wasn't patient enough... as usual. Thanks again.

I don’t understand your question, however, I usually leave the caps loose because many times I’m charging after I’ve refilled with distilled water. The caps are vented in unless they’re clogged you really don’t have to remove them when charging
Except I don’t charge trust most battery chargers unattended. I look at the meter and when it drops to half of what it started at, usually in 24 hours I unplug it.

Great video one fast tip new or old battery if you charging before charge see if you can open the cells tops if you can open them and and ✔️ chek if the liquid is on all the cells this is acid so don't touch if one of them is empty or not fill add destile water not regular water destile water live the tops open during a long charge after is charge let it cool put tops back in and be ready to use the reason why they explote is becouse one cell if is got low acid when charge will fill the empty spaces Whit Hidrogen and when you add a load it will spark and boom 💥

Hello! Thank you for great information. I got a new battery August 2021 but went dead this week because of cold here in Toledo and I have the old fashioned battery charger. Do you think that it can fully renew it or should I but a new one?
Great and useful video. I want to ask about an old car battery charger I have at home and on it, there is a switch which has N and S. Any idea what this switch is ? Thank you
I looked around and couldn’t find anything, maybe you could search and find an old manual for that charger and that would certainly spell out what N and S are.
Deep cycle is for the camper or similar battery that can run down to zero. Use your regular charging mode because your tractor is using a regular mode battery.
I bought a 3.8amp powertec charger for a trickle on 170 amp deep cycle to maintain charge , the booklet says it will only do 120 ah, anyone out there know if it’s still ok to use? Jef
It’s usually half of what it started out at so if it started out at 10 and went down to five that’s usually OK. The age of the battery means a lot too, after four or five years of age things start going downhill.
My battery is showing a different charge level between the 2 amp setting and the 10 amp setting. The 10 amp is at the #2 mark, the 2 amp setting shows it's below the 0 mark. Why would this be?
Can you get batty to begin to boil some with the big 50 amp? I bought a 75 amp charger but returned it as can not equalize the charge... no boiling seen 5 hours of charge -I may end up with 200 amp but hope not too huge
50 amps will definitely boil the electrolyte in a lead acid battery. 1st, clean the battery, pop the caps off and check the fluid levels, top off if needed with distilled water. Check the battery voltage, if below 4-5 volts, run the charger (manual mode) 30-40 amps, it should start 'boiling' for about 10-15 min, monitoring it constantly and watch for boil-over. This should get the charge up enough that a smart charger that has a desulfate (pulse) function, can do the rest safely. If you are in no hurry, 2 amps is best. The recovery process can take several days to weeks, depending on how badly the sulfation is. Patience is the key.
My car battery charger says 6/2 amps. I've always used 2 amps because I assumed 6 amps wore out the battery faster. Is that true? I've heard of overcharging, but I've left batteries charging on 2 amps for 48 hours without problems. I assume 2 amps is good for charging and going to bed zzzzzz and 6 amps is good for when you need the battery charged in a hurry.
You are correct, I use 6 A when I hope to get my battery up to speed that same day. I use 2 A just like you said for about 48 hours to bring the battery up slower and get a better charge. One precautionary thing I do as I keep the battery in the charger on a metal shelf so if anything ever went wrong with the electrical device that I’m not watching if it goes bad it won’t catch anything on fire. Just a little tip not mandatory.
I need a 1 volt trickle charger. Can I take a 6 volt charger to charge a 12 volt battery? Can I put a inline draw like lights to pull the volts down to 1 to two volts goin into the battery?
You mean a 1 amp charger. No, do not use a 6v charger to charge a 12 battery unless you put two 6 volt batteries in series. Again, we're talking 1 or 2 amps, not volts.
My battery is dead and I took my battery out the car and is charging right now. Is it ok to charge it at 6amp? Thats the highest my charger can go to right now. CCA is 630 so I just set my alarm for about 5-6hrs for it to charge? I just hope that I didn’t miss anything along the process of charging it cause this the first time I’m charging a car battery
