I also have had good luck with the Odyssey batteries. We use two of the 925's.

Optima yellow top any good for drag racing ? I saw one in the Fletch's stocker wagon @ Indy.

Optima yellow tops work great since they are a deep cycle battery. However, you also need a charger made for this type of battery. Sears makes one and I think Optima also has one.

I've run an Optima yellow top for years. One of the best batteries I've tried, albeit somewhat heavy. It may have been wrong, but I always used a standard charger on it. Never had a problem.

Likely referring to a slow charge on 2 amp or similar ?

I usually slow charged the week before I went to the track. I don't run an alternator, so there was more than one time between rounds when I'd put the thing on kill until I had a fully charged battery.

With the higher end "S" brand charger I've noticed a voltage creep going beyond the normal 13.2-14V up to and over 16V at times with 2 different chargers. If I catch it, unplug the charger and plug it back in it'll stay at less than 14V from then on. I mentioned this situation to a couple of other racers and they found they had same creeping problem. This also happened on lead acid batteries that I was charging over night and the acid was boiling by morning. Now I won't leave a charger running, only a battery tender. Please stay aware!

What's the proper way to charge an Optima if not with a standard charger?
