Battery rejuvenation

I've read that too looking at the Advertisements for the newer generation maintainers. Some thing about "pulsing high frequency to reverse Sulfication".
I have a maintainer that I rotate across a bank of stored batteries for the winter. I'm guessing it does help as I seem to be getting a few more years out of my 6 volt car batteries.

Let us know the results, not sure how many batteries I have between machines, motorcycles, trucks, trailers must be over 35. I use deltran battery tenders including a 24V but if there is something better I'm in

Hey Team,

"He who Dies with the most Good Batteries Wins"!!!!
Hahaha

I called the tech department at Clore Automotive and asked about the ability of their charger to renew old batteries. The tech guy said that they will improve "lightly sulfacated batteries." My very limited test seems to back this up. The original battery described in the first post is still showing around 800 CCA. The second battery which started with 470 CCA out of the original 800 was not improved with a 2 week run on the charger. It is still close to the original 470.

I currently have the charger on a Blue Top Optima with an original CCA of 750. It is eleven years old and it now has around 100 CCA. I do not have much hope here but it is worth a try.

You cannot buy these chargers directly from Clore. They are the manufacturer and sell to retail outlets. They make several models and I think this line is called Pro Logic. Mine shows no Clore model number but I think it is a 2320. There are other maintainers making similar claims so check the descriptions and give it a try. They could be very effective if you start early in a battery's life.

My friend Larry has a Honda 4 wheeler that still starts in our winters on the original battery. It is 12 years old this summer. He takes the battery out once a year and shakes the begeesers out of it while holding it upside down. He then gives it a 30 amp quick charge for 15 minutes or so and puts it back in the machine. He claims it keeps the power robbing deposits from sticking on the cores. So far it working for him. Now how do I shake my 100+ pound Cat batteries?

Interesting Roger, never heard of that.

I guess i can use my industrial paint shaker for batteries now.

I was told one of the reasons that newer car batteries fail early is that the distance between the bottom of the plates and the bottom of the battery is much less than it was previously, ( a manufacturing cost savings?). Anyway, in this case a battery could fail when the sulfate falls off the plates and fills the bottom of the battery up to the plates and therefore it shorts out. Does shaking it upside sown remove any of the sulfate? If so, that might help longevity of the battery.

Good luck

When I was in HS I had a 47Ford PU. I added at one time some magic powder that was supposed to keep the battery like new. Well during the winter when the PU was not driven (no $ for gas) the battery froze and cracked.

After that it would not hold water but I just kept pouring water in it and it ran the whole next Summer.

I never kept track but I think between battery water and engine oil it was a match as to which used the most.

I've never known what that stuff was but it came in three small tubes, one for each cell of the 6v batt.

Note: drove that PU most of the way thru college before upgrading to a 48Buick. Wish I had them both now.

Its always been my understanding that its the sulfate build up in the bottom that kills the batteries.
Though I will admit to seeing a fellow take a dead 12 volt out of his Farmall H and shake it up and down to get a very cold tractor started one winter. (about 25 degrees F) He claimed it stirred up the denser cold acid with the water.
Following weekend (It was about 5 degrees F) I saw him I saw him take the same battery and turn it upside down on top of his truck battery (post to post) to quick charge it to crank the same H! Darn thing had enough to start and we had to work that day! :jaw:
