What type of battery

thcri · Oct 11, 2005

Wayne,

Go back to your dealer and tell him to give you a new battery. I did and got one free. Others here have also. Your tractory is less than two years old. My dealer gave me a new one, a gel type battery and I haven't seen a bit of corrosion since.

I'm with Murph, but in our case it took a letter to New Holland before the dealer reimbursed us for the battery, still it was taken care of. Here's our fix

Steve,

I suppose SLA/LC batteries can vent a bit, but the calcium in the plates is supposed to absorb the gasses and prevent bubbling.

Vibration tolerance is where AGM batteries (such as Optima) really shine. )

I'm sure you are right, maybe I've just had bad luck. I would think an SLA should work fine, but my experience has been different.

I've got an SLA on my Generac standby generator. About a month ago I had to spend a few hours cleaning up the positive terminal. There was a bunch of corrosion and liquid acid laying on top of the battery under the positive terminal. On both my tractor and my generator any acid blowing around gets sucked in by the cooling fan and blown all over the radiator, motor, etc.

My dealer just replaced it after two years. No questions asked. He even sprayed some junk on everything to prevent everything from corriding up.

No Charge.

This is the reason I went with the dry cell battery. About the same price as an Optima, but without the acid.

Had a NH33D, same problems with the battery. But at the time I was trying to keep the water level up to where I would normally keep it in a car battery. Once I let the water stay down to where it just covered the cells, my problems seemed to be a lot less.
Most of the problems seemed to come from the gasses, the upper radiator fins and hydraulic hoses seemed to get the worst of the errotion. (You have checked those hoses, haven't you? /forums/images/graemlins/wink.gif. The battery itself was always dry and had very little post corrosion. If I needed a new battery, I think I would get a gel cell.

You can also use Vaseline on the terminals. It's dielectric so you can use it between the posts and terminals. Clean the posts up, then smooth some around the post then attach the cleaned terminal. Last a couple years on a car. Smear a little more on top and bottom of terminal before attaching. Cheap, simple, and you can still see the parts to check on em.

In order for grease or Vaseline to protect my tractor from acid damage and corrosion I would have had to coat the battery terminals, battery shelf, front latch, radiator, grill, hydraulic cooler & hoses, motor, and a bunch more parts.

Jimmy, I have to correct you on your inferred definition of "dielectric." A dielectric is a non-conductor. If you put it on the battery posts before putting the terminals on, you will prevent corrosion, but you will also run the risk of insulating the terminal from the post. I suspect that when you tightened your terminals, they squeezed out most of the vaseline and actually established metal-to-metal contact.

One use of a white dielectric paste is on power transistors as a heat conductor. It is used between/around the mica insulator and the bottom of a transistor to conduct heat. It's a good heat conductor, but an insulator for electricity.

You don't have to take my word for this. Dielectric is defined in Websters dictionary.
