The Dyna Batt weights 13.5 lbs. Its a dry cell so no splashing. Great for autocross. The downside is the reserve capacity is lower than a regular battery. All that means is you can’t run things without the car being on for a shorter time. But saving 25lbs is worth it. I put some new post ends with rubber boots on it.
Here it is mounted to the battery tray. This is a good time to repaint the tray also.
Side view of the mounting. I drilled new holes for the mounting of the universal hold down kit.
I used nylon bolts versus metal. Saved like only 4 ounces but cost like $2 more. 😛
Here it is back in the car. I am now using a Hawker 925 Dry cell battery.
