Getting my father's 2005 dodge ram 5.7L 4wd 1500. It has a 4 year old Farm & Fleet (Johnson Controls) battery that was poorly kept over the past 3 years after he became parapalegic. It was run for about 30 minutes once a month appx. so it has been maltreated and never taken out in winter time over this period of minimal use. It currently somehow still starts the truck, not robustly but starts it indeed.

I don't want to ruin a $300 alternator for a $80 battery.

It is appx. 700 -800 CCA top post. Any genuine way to top it off with charge to make it whole again or is it likely a sad excuse for what it once chemically was?

Any charging regemine you recommend to top it up? A formula?....A certain amps over certain hours per hundred CCA?

Buy a new 80 dollar battery.

If you have an automatic charger and a voltmeter, charge the battery until fully charged.

(This is the part that some people will not agree with). With the charger off, turn on the headlights and monitor the battery voltage until it drops to 11 volts. Repeat this cycle 4 to 6 times.

If the time it takes to drop to 11 volts increases with each cycle, that is about as good as it gets. If the time it takes to loose voltages gets shorter......Get a new battery.

The only thing I would consider other than a new battery is buying one of these and putting the battery on it for a couple of weeks to let it run its full 7-stage cycle a few times:

I have a decade-old shoe-box sized Vector (now Black & Decker) 25A charger with a recondition mode. I can put a battery on it and it alternately charges and discharges the battery until it declares it reconditioned (or errors-out).

It's never fixed anything. The batteries I've tried the recon mode on, were all near end of life, and continued their downward slide.

On another note, the charger has a 75A jump-start mode that does absolutely nothing. Not one Amp.

After B&D took over, they re-introduced the same charger, only they made it 5 times larger. The Vector I have is a good, intelligent charger, with AGM, Gel and Wet modes as well as 2A/10a/25A charge modes. I found a wheeled charger/jump-starter at a yard sale and repaired it, so together they take care of all my 12V charging needs.

Does it work? Great. Does it not? Replace it. Why does it have to be more complicated then that?

If the truck starts like butt its probably not your battery.

You could put it on a BatteryMinder with a desulfation mode and it would take a week or two, but the battery will get desulfated and be a better battery.

Why would a low battery ruin the alternator? For new I put two Motorcraft MAX batteries in my Ram. Good price and warranty.

With all the modules and not to mention the alternator it is unwise to mess around with weak battery's. I replace my battery's every 4-5 years regardless of how they perform.

A weak battery forces the alternator to overwork, it is also hard on computers which need the correct voltage and current.

I know for my golf cart I tried the magic juice they sell like this a charge and it worked!

I'm not sure exactly what the differences are between a golf cart battery and an automotive battery but I would think you could do something similar.

If it was me I'd put it on a slow 2amp charge till it was topped off and use it.

Run a Battery Minder in delsulfation mode (as mentioned above), get a cheap solar battery charger from HF or Northern Tool to keep it fully charged, both have saved me mucho dinero on batteries.
