Optima Battery Installation, I just installed one today. Options

I thought I would share my experiences with installing an Optima Battery in my '76.

After reading about Optimas on this forum, I ordered the Red Top, Model 34R.

I got it from www. 1st-optima-batteries.com.

It cost $134.95 with free shipping.

The battery came with a Group 78 adapter, and two Group 65 adapters.

On my first try, I found that the battery was too long to fit in the battery tray of my car.

After some helpful tips from Tod914, I was able to install the battery easily.

Out of the box, the 34R was about 1/2 inch too long. Per Tod914's suggestion, I used a coping saw to cut about 1/4 inch off each of the four (4) extension tabs on the base of the battery. I smoothed out the cuts using a file.

I used one of the Group 65 adapters on the back side of the battery base. This adapter is a "tab" that allows the battery edge to fit under the battery tray lip on the right side.

I then used the Group 78 adapter in place of my stock battery hold-down, and bolted it in place.

If anyone is interested, I can post some photos of the adapters.

Time to go for a ride!!!!
