Car won't start in COLD WEATHER? Renogy Solar Battery Trickle Charger

[paveljelinek]

❤❤❤ you battery was not sulfated much, since it bubbles great on 10A.. i'd watch the battery temperature and if it would not come past say 45°C, i'd desulfate overnight. The cycles are not important you know, the battery temp is.. edit: as the internal resistance of the battery goes down, less volts are needed to get the same amps go in.. so you're right with the voltage.. that's why - if you want 101% desulfation - you need the last cycle at least 50A.. and i saw a guy who was doing this at 200A (i'd personally not go that high)

I did a combo of DC shorting and Flushing with Baking soda first, flush thoroughly with tap, then warm water and add Epsom desolved topped up and on snart trickle charger. Then flush out with warm water few time to rid of baking soda residue. Add back original battery acid and do both trickle and DC shorting charge ( start low, x 10 min intervals, turn up to 30amps or bubbling in all cells). Load test after 5 mins to see it reads at least 70-80%. Disconnect everything and recheck CCA result again next day. ( load test). If it hold up to 70%, your good. Now hookup to car as 2nd battery with relay switch so while car is running, the alternator will auto charge your 2nd battery when first battery has been charged. I have my 2nd backup battery ( load tested at 100% everytime) sway that for weaker batteries that you don't use often and you can have batteries for other uses to use eg. Emergency lights, water pumps, cellphone chargers, cheap Diesel heater, etc. but eventually when lead plates break down ( too brittle), its time to strip everything you can salvage for rebuilding other batteries. I taje back failed batteries for the acid and lead. Hard to find any retail willing to sell battery acids.

As the battery gets stronger it will pull the welder voltage down to its voltage.

[TheRealJerseyJoe]

Science is fantastic. Great result !

If you want to restore lead acid battery's to new condition read The Automobile Storage Battery Care And Repair by 0. A. Witte. It was written in the 1920's but is still useful today on lead acid batteries, has electrolyte SG charts, internal plate cadmium test information, and full tear down and rebuild instructions.

[juhavuorinen]

It's desulfating, so the internal resistance drops. Therefore, voltage drops and its charging it self. When it's full it won't take amps but voltage rises and eventually it will explode, hence the voltage limiter in proper battery charger usually about 14.4v.

[philventura]

About time one of you actually explicitly said ground goes to negative and positive goes to positive. Too many of you people are showing the battery hook up without telling which one is which. None of you actually said don't use an AC welder

Putting a high charge to the battery releases the sulphuric acid back into the electrolyte. Have you tried just replacing the electrolyte with a specific gravity of about 1.3? If the plates still have capacity to absorb more sulphuric acid it should be a cheap and easy way to keep using an old battery compared to forking out $250 for a new one.

you don't have to use a stick welder or even a 220v welder, i do my batteries with a 110v mig set up for flex and it works fine, you just have to be mindful of the duty cycle, 110v welders have shorter Duty cycles, also from my experience there is no set amount of time, what i've seen is it depends on the condition of your battery, if you have cells that aren't bubbling when you start then you have to keep doing it until they all are bubbling equally. because i use a 110 wirefeed welder i use jumper cables to connect battery to welder that way i can stand back and pull the trigger for 30 second bursts with a couple minutes in between for the duty cycle and keep doing it until the battery reaches above 12.5v in between burst then put it on a smart charger and let it charge to 100% then the batteries good to

[rosschizzoniti]

The welder is Great idea but must be kept on for a short period of time as the voltage climbed above the 2.4volts of each cell allowable to three volts, which if left for too long can shorten the life of the cells and destroy the battery! Once the battery is fully charged it should be left at approx 12.4 volts. and is sufficiently Charged. ongoing maintenance is necessary to extend the life of the cells in the battery and is a must, also the use of an hydrometer to measure the gravity of each cell is very important to get a idea of state of charge for each cell, doing this will prolong the life of the battery.

Check out "PulseTech" Xtreme Battery Desulfators. I have used these units for years on all of my gas engine driven welders as well as all my vehicles batteries. They stay hooked up 24/7 - 365 days a year. They constantly pulse the plates inside the battery and also charge automatically if the battery needs it. I also use them on my golf carts after being fully charged up with the Golf Cart charger, I connect to the PulseTech while I'm not using the cart. They supply "quick connects" so they are very easy to disconnect/reconnect. I have had great success using these units and they have saved me a ton of money especially on very expensive 36 Volt Trojan Golf cart Batteries. Just some FYI for what has and is working for me anyway.

I’m about to try this but man that is a stout lil unit you have, 200amps wow

[pauloremez]

Uh you shouldn't have your Cable Coiled up like that Bro when you're using it

[richardyao]

Hydrogen gas is from electrolysis, not boiling.

[gthomas]

To be able to use it back in the car the internal voltage is not important much as the CCA or cold cranking amp.

[darrylmonat]

If vehicle just sits, disconnect the battery. Everstart Maxx batteries are one of the best batteries on the market. I get 7-9 years from the many I have had. I am extreamly surprised to see this on a Maxx.

[frankiebuttigieg]

Thanks for now I tri another battery and see what happened.good Channel keep good work I let you know

[francoisverdoes]

I got a mattweld 200 amp dc inverter, but it do not work on any battery.Why is that?..please help

[DIYBill]

Honestly I don’t think you need to charge it again after passing so much voltage and current thru it. I would have considered it successful if the battery voltage was holding around 12.8 -13.2
