I have used Optima yellow tops for 20 years. Every 4 years or so I would replace it with another. The old battery went in the trailer to power the winch, laptop etc. The trailer had solar on the roof to keep the batteries charged. My last trailers batteries lasted 14 and 12 years. Tom is correct over voltage will kill and Optima battery, 14.5 volts. The Optima battery charger is very good and so are battery tenders. I have always had an alternator on the race car. A red top is fine to use but should have an alternator. The yellow tops have a longer reserve capacity and are designed to recover from a deep discharge. The yellow tops are both a deep cycle and a starting battery. I worked for Johnson Controls for over 12 years, they own Optima. There was a quality issue for a while when some of the batteries started to be built in the new plant in Mexico.
