I'm tired of replacing the yellow cap resto battery every eighteen month . I know there was a post awhile back on how to gut the case and install a normal battery inside.
Does anyone have a step by step on how to do this ?

You need to drive the car more or keep it on a trickle charger. Mine lasted 5 years.

Was the last one you bought the AGM (Absorbent Glass Mat) technology or the older style?

Have one of each and they are on battery tenders. Seems to me your last two batteries were not resto batteries unless it's in your 1990 + Lincoln.

You must be getting old because your feeble mind already forgot you were with me when my 5 year old resto failed in Wildwood.

Addressing the original question posed...


You might try contacting Randy (1_WILD_RT), who has done exactly what you describe.

Basically, to gut the battery you need a large metal pail, baking soda, fresh water, long heavy rubber gloves, face shield, eye protection etc....

Small disclaimer....

YOU ARE DEALING WITH HIGHLY CORROSIVE BATTERY ACID
PROCEED AT YOUR OWN RISK
I TAKE NO RESPONSIBILITY FOR YOUR ACTIONS

I drilled holes at the bottom of the case to drain as much of the acid as possible. I work in a bus maintenance facility that has provisions for acid battery flushing & washing so this step was easy for me.

After throughly neutralizing the battery as much as possible (the glass matting will still hold acid) I figured I would try to cut a square out of the bottom of the case & all the guts would fall out....NOT!
The case is molded with plastic separators built into it to separate each cell.
I have heard others cutting the top of the battery off but I wanted to hide this battery as best as possible & I didn't want any potentially visible seams.
Secondly, the case is VERY thick plastic on the bottom & fairly thin on the sides. You have to be careful not to crack the side of the case when you are breaking out the plastic separators molded inside.
I used a whizz wheel for this along with a good dust mask because you WILL be black when you finish cutting the bottom out cell by cell.

Starting at one side of the case, after the bottom of the cell is cut out, each glass mat is separated by a lead plate which is attached to lead lugs at the top of the battery. There are aprox 6 lead plates & mats per cell. These have to be wiggled & broken off the lugs to remove. AGAIN WEAR HEAVY NEOPRENE ACID RESISTANT GLOVES!!

After removing all the plates & mats in one cell, break out the plastic separators, cut out the bottom of the next cell & move on till they are all out.
Wash out the case & then proceed to take out all the lead plate retaining lugs except for the 2 that the posts connect to. You have to take the others out to fit the new battery in the case. I used a Dremel tool with a small cut off wheel to cut through the lead.

Lastly drill out a hole in each post lug & make up some short battery cables to connect the new battery to.
