The G-503 Jeep requires a Group 2 Battery which has industry specific dimensions.

Hello Farrel
Will the top be in the 'loose' form, i.e. not bonded to the case so that people can put their own battery in or will you be putting a battery in and bonding the top on?

The top will be removeable to facilitate replacing the actual battery when it eventually dies. The cases R.A. will be making are simply housings with correct cosmetic features.

Thank you for the reply. So the under side of the dummy terminal has an eye type terminal on it, is that correct?

I don't understand your description..

The basic prelimenary plan is to have an outer case with correct cosmetic features encase a modern (maintenance free) battery, and do whatever it takes to accomplish that. I don't know how the battery terminals will be exposed yet because we haven't made it that far in R&D.

Had a thought 'outside the box' :D that if you could put two 6V Lithium Potasium batteries inside there and wire them in parrallel for more amperage (6V), or wire them in series for the 12V Jeep owner, you would have a tailorable voltage output for the end user.

Accidentally applying 6V to an apparent 6V battery internally wired for 12V would not kill it anyway.

So two (or 4) batteries stuffed inside wired up for the desired voltage (like the Deuce has 2 ea. 12 volters for 24V or M900 series has 4 ea. 12 volters for 24V). Then I saw some of the prices of the LiPo batteries (at least the 12V version $795 :shock: ... 6 V $55ea.and think it may be cheaper to stick with a single Optima...(as long as they stay in business 50 years :lol: )

Hi Farrell

What it is the imnnside measurments of the battery casing. so we know what kind of classic battery size we can use here :D
You are doing a fantastic job on this

Hopefully the smaller batteries installed inside the repro cases will have same capacity as the Group 2 OEM battery.

Nikko,

At this time I do not know since we have not finalized any of the prototypes or chosen a particular manufacturing process. The cases you see are prototypes meant to assist in R&D, not the final product. Additionally, the top details still need to be copied from the original dealer sample we acquired, and transfered to the prototypes for further R&D. I expect this project to continue on for many more months before we have final specs.

I believe that the current version of the Optima that many of us are considering exceeds those specs and lasts often up to ten years.

I am working with Optima RedTop 6-Volt Battery 9010-044 as my basis for fit and alignment. I have one in hand and am working on fit and alignment - both within the battery case and the top.

I anticipate that minor modifications will be necessary to the battery, specifically sanding off the square tabs on the base.

Based on the Optima height, and that of the original battery case, we will most likely use the existing optima terminals to protrude through the top of the case rather than have any special internal connection.

The battery case will be an exact copy of the original externally. The top will be a part in the style of the original, incorporating direct castings of original design elements, arranged so that the assembly "works" while retaining an appearance as close as possible to original photos. I expect the top will look like an original, but will have minor placement differences to an original of terminals and vents.

If you need some measurements on any battery brand we use, let us know. I can provide measurements on the Interstate battery. But it sounds like the use of an Optima battery will work the best. With a regular battery in the case, you would have to fashion some short cables to join the terminals at the battery and then affix them to the "dummy" terminals sticking out. The dummy terminals would have to be really affixed to the case so you could remove the cables from time to time without them coming loose.

I don't know how much the Optima battery is for our jeeps, but I do know someone sells a Willard battery with an Optima installed for $300.00. Shipping will be extra. Probably a lot extra Plus, I'm sure Farrells repo will be spot on accurate.

Great work Farrell.

A fantastic project Farrell! :D
And a great thread! The knowledge shared is amazing.
I, too am interested in one of these.
