1850 battery question

jason, NW Ontario · Sep 18, 2011

I've got a new, load-tested 780 CCA battery on the 1850 diesel, and I only get about 4 starts on the tractor before it doesn't have enough juice to turn the crank.
What battery size would you go with instead? Going to go shopping tomorrow.

Before you buy another battery,have your starter checked -it may be needing to be serviced.Also,if the tractor was designed for two 6 volts,thats what you need to stay with.Dont try to 'save' money and "get by" with one 12 volt.BTDT Steve

As I recall, those tractors were 12v from the get go but used two 6 volt batteries. Anyway, do you have a voltmeter? Is the new batterry you bought getting recharged properly after starting? It sounds like maybe it's not. If it can start the tractor once, twice, three times and then doesn't have enough umph to start it again----doesn't that sound like it's not being recharged between starts? Also, weren't some Olivers of that era still positive ground? They changed over somewhere in the 60s to neg ground at the request of the govt due to radio interference.

The alternator is showing almost 13 volts charging.

The manual says size '5D'(AABM) batteries in series - what size of 6V battery X 2 would I put in there?

jason, NW Ontario · Sep 18, 2011

I found this battery, two of which would be about the same price as one 12V with about 900 CCA... Does it look okay? I'd just need a short, fat wire with a terminal clamp at one end and an O ring at the other for the series connection. Worth a try - getting the starter tested out in the sticks would be tricky.

thats a lot of oomph for the same price

"The alternator is showing almost 13 volts charging." That's about one volt too low. Where to find batteries? Agco dealer should have a parts list on computer. John Deere will probably have info and batteries. If that's not an option, I would get the biggest batteries designed for farm use that will fit. Remember, tractors are unsprung machines and it's better to get a battery designed to take the bounces.

jason, NW Ontario · Sep 18, 2011

There is no ag dealer anywhere in the area. The farmers' Co-Op, if I recall correctly, usually carries Interstate batteries that look pretty big but I've never looked up close.

I'm not famialar enough with the Olivers to tell you which battery it needs.IH tractors of that vintage/size range use 2 long skinny 6 volt batterys.IIrr,my neighbor's early 1800D uses 2 small square batterys.Your local NAPA store should be able to help you.Steve

jason, NW Ontario · Sep 18, 2011

We have a NAPA, so I can try there in the morning, as well as Crappy Tire (the other 6V I found).
I thought 950CCA per 6V was pretty impressive though!

HELO · Sep 18, 2011

That is impressive. My biggest tractor with a 411 cu in diesel came with a 960CCA batt.

Sounds to me like the alternator is weak for some reason. Belt tight? Twist the belt. If you can twist more than one half turn, it is too loose.
Put a voltmeter on the battery when it is fully charged, and a good battery and when you start the tractor the voltage should not drop below 9 volts. If it does it is a sign that the starter is draging. I have turned the bushing around in the starter before. ha

jason, NW Ontario · Sep 18, 2011

I think all I'd need is the 2 X 625CCA per battery, about $140 plus tax. Not bad.

jason, NW Ontario · Sep 18, 2011

I can try the alternator belt also. The battery I've got in there was a bit of a gamble: a refurbished battery. Bring in your old one, and you'll be provided a newly refurbished battery, load-tested, to meet or exceed the CCA of the battery you brought in. Sounded too good to be true, but figuring I'd only start the 1850 30-40 times a season made it worth a try. For $40, it was worth a try... sort of.

cost only 40, got 4 engine starts, then recharge

Check the battery with a hydrometer to find the state of charge.You should be at 13.7 volts when charging.

Fern(Mi) · Sep 19, 2011

We've 5 1850's and bigger Oliver's around here. Considering yrs of service and cca we go with 2 6v batteries every place we may fit 2 or more.
These heavier batteries last 6, 8, & 11yrs. dependability and money wise the bigger 6v batteries save us over the long hauls.
my 2 cents

Alternator showing almost 13 volts charging IS BAD. A new well charged battery will many time show a voltage higher than the nominal 12.6 volts which is almost 13. Alternator should charge the battery to 14.4 to 14.6 volts. You have a CHARGING SYSTEM problem.

evilboweivel · Sep 19, 2011

you got enough battery
fix your charging system

the tractor vet · Sep 19, 2011

You should be running over 1200 cca on it one 12 volt even a group 31 will not get the job done for long. Then there is the matter of the starter if it is not up to snuff it may be dragging and drawing more amps. And like others have said how's the charging system ????

Traditional Farmer · Sep 20, 2011

You don't have enough battery,I have 2 1000 CCA
batteries in my 1650D and they are enough but not too much especially in Winter when I need to preheat and then start.Best way to ruin a starter is not to have strong enough battery.
