Almost forgot that one the t&t with the 32LB. battery my car picked up with the 16 volt over the 12 volt. Went from a 9.97 to a 9.89 ET. I had run two passes with the 12 volt at 9.98 and 9.97. Switched to the fully charged 16 volt after the cool down and went 9.89 on the first pass. Before the 16 had fully charged they made last call to the lanes and I took the charger off while still charging at 8 amps and slowed to 9.93. I drove back to the trailer and shut the car off to talk to the friend I had just run. When I tried to start the car to load it grunted and clicked and did not start. I reinstalled the 12 volt and it fired right up to load. After loading I checked the voltage on the 16 volt battery to find it showed 16.65 volts and would not start the car.
Tried again at another track with the 16 volt. Fully charged at home. Loaded car, unloaded car, drove around pits warming up and ran fan and water pump to coll down. Drove to the lanes only to have a no start in the lanes. Four starts and a short cool down and no start. Car would always start on 12 volt so I got the tools and switched the cable to the 12 volt post on this battery thinking that maybe somehow my starter just plain didn't like 16 volts. Still no good. Still showed 16.67 volts when removed to reinstall the 12 volt battery. Seems to have volts but no amps.
