I bought a new group 51 battery for 20105 the other day and today my forklift battery died so being as how the forklift gets used daily and the JH will not be ready for a drive for a few weeks (now there is optimism) I decided to investigate what can be done to improve the battery situation.
So far I have come up with:
1. Just get another battery and be done with it.
2. Cut out the sheet metal spacer to enlarge the battery box.
3. Move the battery to the trunk, and use the battery shelf for the carbon canister and an oil puke bottle.

What have you done and what are your thoughts?

Thanks
Robert

Since I actually use my trunk and don't want to cut down on available space, I left my battery in the stock position. There are other choices for a battery too, one is the Mazda Miata battery which is smaller and lighter than the Group 51. Its drawback is that it's usually pretty pricey.

What's the issue with the battery?

The car already has a 51% rear weight bias, why move the battery to the boot?

No real issue with the battery. I am new to JHs and would like to know if it would it be desirable to have a larger battery? Are the Honda and Miata batteries doing the job adequately? Was the original battery larger than either of those batteries? The only advantage to putting the battery in the boot is that it will last longer and could be sized however big you wanted. Put an 8D battery in the boot and it will handle like an old 911! Ha!

My last JH battery was in use for something like 12 years (that one was a DieHard), so I'm not sure what needs improvement?

You're not paying for size, but cranking amps. Unfortunately, these days, most batteries are made by a few big companies with various labels slapped on. I've always had good luck with the batteries AutoZone sells. A Group 56 is the best fit.

I also used a group 56. As for brands, Interstate is very good. Or you could use a dry cell Optima if they have one in that size. Gary

There is an AGM battery available from "Lifeline" batteries in Azuza, CA. They also make Concorde aircraft batteries and others. It is their item No. 1257 TB racing battery. Perfect size mounted in reverse (positive on the passenger side) with a little trimming to the non essential part of the plastic case. About $130.00  If you don't drive often then a "BatteryMinder" or other similar AGM specific maintainer is a good idea.
