Never heard of them. Never heard of Pasco battery, either. Is Precision the company that makes them or just the label on them? Find out who makes them. Personally, Deka is still my favorite (although you can find it under the Duracell labeling, too). If I bought anything else, it would be made by Interstate. I see you're in MD - there's gotta be other stores around that carry Deka.
That's about what Deka's sell for around here - a little more, a little less, depending on which group 24 it is.
Here's my options for group 24 batteries
1. West Marine : 675/550 Amps, DUAL Purpose battery, warranty is one year free replacement. Cost $160.00 Made by East Penn Manufacturing / Deka
2. NAPA: 675/550 Amps, Dual Purpose, warranty is 3 month free replacement. Cost is $100.00. Also made by East Penn / Deka.
3. Deka Dealer: Local guy around here had no interest in doing a special order for me. Keep looking.
Seems like the same part numbers but you're getting a much better warranty from West Marine. With the length of time my boat sits on a trailer, that 3 month warranty would be a really bad deal.
Dennis, in answer to your question about Precision, that is only a trade name. Precision is made by Continental Battery, and from what I can see, Pasco has a large ownership stake in Precision. After digging deep into the facts, Precision doesn't make a dual purpose battery - only starting types.
Thanks for the input.
