Why No Round Posts Batteries for Lawn Tractors

[Egon]

Any chance the garden tractor battery has a different service rating than a standard car battery.

A piece of copper tubing and soder can make a variety of different adapters. No crimping required.

Surely. ... And no doubt inferior to a mid line or better car batt. The best bet is to find a car batt that fits. Economy of scale; better quality control, a warranty, greater electrical capacity, ... and no fooling with adding adapters/more connections in a high current circuit.

If anyone here thinks that a car battery will fit in a lawn tractor, think some more. The space I have is only 8-1/2" length x 6" width x 8' height. That is the limits for a battery. I don't know of any automobile battery that small size, and available, The Die Hard LG-3 is 8.25" Length x 5.25" width x 7.25" height. and that is tight space to be installed. There may be larger lawn/garden tractors that have a larger space, but, I don't know of any.

BTW. I installed the Die Hard and made the flag to round post connectors and attached the cables and all went well. And thanks to all for their input here.

Apply a good corrosion preventer and you'll be fine.

Depends on the lawn tractor.
I have a Bolens that takes the same battery as my 4 x 4 GMC diesel did!
Shucks enough battery that I could drive it home without gas in the tank, LOL. (if the starter would last out)

All the pertinent info was in the OP. Just gotta read (and comprehend) it. Maybe you & Larry can figure out what car or truck battery will fit the posted space.

My JD 345 battery just went south after 5 years of use. It has the "round posts" for the original cables that was installed by John Deere. All the batteries that are available today have the so-called "flag" posts. I could just go back to the dealer and pay another $120.00 for one with the round posts, or buy new cables with the ends for the flag posts. I don't need replacing the cables as they seem to be in good condition. So, I'm buying two adapters called "Flag to Round post" which can be bolted to the battery with the flap posts and still use the cables with the ends that are for round posts. Costs: about $10.00 for the two. Sears Die Hard battery...Model 50785.. costs $48.14 will fit...Size: 8.1/4" length, 5.1/4" width, 7.1/4" height will work and just about the same size as the John Deere brand.

Has anyone with a better idea?

No, the pertinent info was in a later post. ... And you never really know w/o seeing it if there is wiggle room and where.

... It is to make it more difficult to use a better and cheaper car batt. For OP -- Use a car battery that fits.

Exactly!

I change the ends out, (and if needed, the batt box) buy a new batt for my car and put the old car batt in my lawn mower!! It's called win win!!

When I refer to auto batteries as not adapting to lawn/garden tractors, it's because of the size. I refer to car batteries as "large' to handle all the electronics and devices on these vehicles. My Chev. Tahoe has a 79 series battery, my Buick Lacrosse has a 92 series. Those old 6 volts batteries were not small, as the early 12 volts for cars. I can see where some foreign cars may have used a small battery, but now to many Americans cars or trucks. The space on my JD 345 wasn't design for a car battery, and there wouldn't be a case to have one (larger one) due to the amount of amps they require.

I am not a battery expert but those lawn mower batteries regardless of the brand I have bought are with long life about two years. Not sure they even put any warranty on those batteries. I have never looked a true "auto" battery but my lawn mowers and gator have room for larger batteries so thanks for the suggestion to consider a true car battery.

As to connecting the round clamp could you not remove the bolt from the clamp, may need to open it up a little, slip the clamp over the flag terminal and run the bolt or longer bolt if need be through the round clamp and tighten it?
