Reviving a dead battery

Postby Papa's Cub » Thu Dec 20, 2018 11:22 pm

I hand cranked my new-to-me cub "Annie Mae" as much as my old shoulder could stand today without so much as a POP. I had the 6 V battery on trickle charge for a little over 15 hrs and left it on charge the whole time I hand cranked it. Although it didn't have enough power to crank the engine over I thought it would at least provide enough power to supply the ignition and the engine would start. I was Wrong! I then pulled the distributor cap and jumped the starter with a 12 volt battery and discovered no spark at the points. In desperation I disconnected the 6V battery and pulled a 12 V coil off of another cub and using jumper cables from a 12 V battery I straight wired the engine and it fired up almost immediately. I had previously primed the oil pump so the oil pressure gauge was up over half way at idle. It was music to my ears when it fired up! The previous owner had told me the tractor hadn't been used much in the last 10 years so I'm a little skeptical about the generator and voltage regulator being in good condition. So tonight as I was searching the web for 6 V batteries I discovered I could convert it to 12V probably cheaper than I could purchase a new 6V battery and Voltage regulator. Before I decide I'd like to know what else might have to be changed besides the coil and the light bulbs. Will the light switch work on either 6v or 12 V ? Any ideas or suggestions will be appreciated, thanks, Tom.

Hi,
You didn't say what year the Cub is, or the serial number. Just wondered if it is 6 or 12 volts. Someone could have put in the wrong battery.
IH changed Cubs to 12 volts in 1964. :)

Sorry about the lack of information. I was told this cub is a 1953 model - serial # 166049. It appears to be a 6V positive ground system. I was so excited by the events of yesterday ( hearing it fire up ) that I completely ignored the subject line. While looking on the net for 6V battery prices I discovered several references to adding Epsom Salt to the battery cells to revive a dead battery. Just wondering if anyone on the forum had tried something similar trying to revive a dead battery. I'd really like to start it on 6V and see if the generator and voltage regulator would continue to charge after sitting a few years. I suppose my first action should be to check around the neighborhood to see if I can borrow a 6V battery just long enough to check the charging system. I could also check with the local parts supplier to see if he might have a core with enough charge left that might supply the ignition. I believe it will start using the hand crank if I can get sufficient spark. ( I don't have much faith in reviving this battery though) Ideas and suggestions are always appreciated. Thanks, Tom.

If you do decide to switch to 12V this is the simplest, cheapest way.

Tractor Supply Company (TSC) sells 6V batteries. A quick Google search revealed there's a TSC at about every crossroads in SE Georgia.

Buy one. See if your electrical system is working. If you decide to convert to 12V, use the new 6V battery in another tractor or make the trek to the 2019 Deep South CubFest (http://www.dscubfest.com/) in Sneads, FL, and sell it to someone. I wouldn't mess around with trying to revive a dead battery. Too many other productive things you could be doing... :)

Light bulbs will need swapped out to 12 volt too if you convert.
Evaluating the 6 volt system will take some time. Connections , contacts, wiring ,ect...
If something is bad besides generator /cutoutswitch /regulator whatever you have , it will be bad with 12 volts too.

I stayed with 6 volt.
Yes it cost money to do that too.
But , dialed in properly with everything working because it is maintained /kept tuned ,it works like it was designed to.

For what it's worth. I have not had good luck with 6v batteries from TSC. l've had 2 literally explode while mowing. Blew the top and front panel off the box and sprayed my lower leg with acid. Neither one was more than 3 yrs old, but had gotten to the point where they wouldn't hold a charge.
The last one l replaced with an american made brand that l've been running for 4 yrs with no problems.
The old saying "you get what you pay for" is true.
It sounds to me like you may need a general tune up, points, plugs, condensor, and maybe a new coil. Personally l would put the money into that before converting to 12v, but that's a personal preference of mine.

Good luck
Hutch

If you have one of the older, analog, 6/12 V battery charger you can use it to hand crank start the tractor.

Disconnect the battery and remove the B, battery, wire from the regulator. Then connect the battery charger.

You can also use this set up to partially diagnose the electrical system.
I have an excuse. CRS.

If you are planning on keeping the tractor for a long time I would change it over because in my own experience you have better cranking power, brighter lights and I can get a whole lot more life out of a 12 volt than I can a 6 and that alone will pay for the change over. Others may have had a different experience but I change every one I get over, even the 130 that my granddaddy bought new in 58

This is a good tip! The company I bought one from before is no longer selling them and I think I paid more than what these folks want too.
As for reviving an old battery I’d see that as a science experiment and that’s it. A weak battery can burn out a starter and overload a charging system. Not sure what a 6v costs but for $50 at Walmart you can buy a 26R 12v battery.
I bought 2 a couple years ago and their still doing fine.
Note: if you change over to 12v the 6v starter and distributor is fine but you’ll need a 12v alternator with bracket, 26R battery, 12v coil , 12v light switch, and bulbs.
It’s an easy job and wiring diagrams are available on this site.

With 6v problems, a 12v upgrade is cheapest and easiest. Also if your truck, 4 wheeler, lawn mower, etc. Is dead the cub can jump start it. Or vice versa. A 6v system is just fine if working right but 12v is much better suited for today's uses.

12 volts is the way to go if you need an electrical system. Also, get a good battery box with a lid too. If a battery ever did explode, it needs to be contained, and not go all over your leg like what happened to Hutch.
If you own 1 tractor you have a interest
If you own 2 tractors you have a hobby
If you own 3 tractors you have an addiction
Anything over that..well your incurable! :lol:

Did a dumb thing once, I was charging the Cubs battery and about 6’ away went to cut a chain with a cutoff wheel. A spark made it over and “BOOM”! :shock: Made my shotgun sound weak.
I swear my ears rang for about two days.
I hear talk about batteries blowing and now it makes me wince.
Not something to be fooled with.

For anyone interested and does not know, the battery charging produces hydrogen gas, the main component in rocket fuel. https://www.studyread.com/uses-of-hydrogen/ No wonder your ears were ringing for two days! Thankful it was not worse.

Hey folks, just for clarification, the ones that exploded were secured in the battery box with the cover screwed down. The force of the blast was enough to bend the flat prongs enough to clear the bolts and blew the front panel forward. Thank goodness that missed my leg. The acid got rinsed off quickly with the hose.
It wasn't because it was a 6v. The problem as l see it is inferior products coming from overseas.
