How about
EastPenn/Deka -
DEKA Intimidator 9A78DT
The rep says the Deka Intimidator 34/78 dual terminal was built to compete directly with the Optima Yellow top. He said the ratings are under estimated and it will test higher than advertised. East Penn / Deka impressed me with their customer service.
I promptly received an email with the warranty information I requested. "Hello, below is the answer to your question.
36 months warranty and 12 months free replacement
Thank You and have a great day "
I also made a phone call to the 800 number. There was a message on my machine from last Friday. Today I received another call. The rep said, " Mr.Lehman?" , I said "Yes". "I understand you have a problem with your battery?". I said "No, I was just inquiring as the the warranty. I was told it was 12 months free replacement and prorated after that for a total of three years warranty." He said "That is correct".
I went on to ask about the recycling. That is true. They have their own lead and plastics recycling. 70% of the lead used is recycled and 30% new. 100% of the battery is recycled. The gases are made into fertilizer. This is one reason they have been able to keep their costs low.
I like the "Green" aspects of this battery.
I took recommendation for this battery from a member here. It is an AGM battery. I like that it uses all the available space, whereas the spiral cells lose some due to the voids between round cells.
Right now I would buy the Deka again. The price is nearly half that of the Optima. I don't see any difference in performance so far. Time will tell.
I had been a diehard Optima user, but between the price increase and lack of consistent reliability in the newer batteries, I have lost confidence in Optima.
In my research I considered Odyssey, but the battery for my application is not dry cell. It is AGM. I did not see paying twice the cost for the Odyssey name.
Lifeline was another consideration. Again cost was the deciding factor. I do hear quality is good.
