Battery: Rock vs "V" Performance Racing Products

05-16-2007, 09:02 PM

I'm looking at a new battery. I tried a pair of 60# Optima's that are rated at 900 CCA and 75 minutes resrve. I bought them as I needed the weight and thought they would keep a charge for long periods. I have to charge each over 24 hours to obtain 13.20 volts. And they drop (installation is + to +, - to - no alternator) to 12.50 volts almost immediately. I then spend the rest of the day at the races trying to maintain 12.5 volts.

I'm looking at this "Rock" battery. It's a 12v/16v three-post rated at 1050 CCA and 40 minutes reserve and weight is 58 pounds.
Also looking at "V" Performance Racing Products 12v/16v three-post rated at 1100 CCA and 150 minutes reserve. Weight is 52 pounds.
Reserve is based on 25amp draw on both. Cost is comparable on both batteries.

On paper the "V" looks better. Am I missing anything? An item that is important to me is fast charge rate using my small Honda generator.

Thanks for any help.

I have the V battery. I learned that you, without an alternator, will need a real 16V charger. I did ok with the maintainer, but I got a very small alternator and it works great. Use the big charger between runs and/or rounds and maintainer all the remainder of the time. Mine will stay at 17.2or 3 all the time. If you let the V get really low it takes a looong time to re charge. I just use the maintainer now, and rarely need the big charger. Just before a run mostly.

Hope it helps your decision, they are not cheap.
