    Thanks, but I was just regurging the info from their PDF's.

    In relation to charging;

    Contrary to what many people think, charging Optima battery is very easy. In this article, we would like to share with you some tips to help you charge your batteries with ease.

    Ensure connection. The first thing to remember is to plug your battery into your charger. If you’re using a smart charger, you will get a range of options on the menu. Simply press the battery type that you wish to charge and connect. It is important that you choose the right type of battery because the mode will affect the kind of charging that your charger will deliver. Charging Optima battery is very easy. Just make sure that you follow the instructions in the manual carefully.

    Clean before you charge. Your battery, while spanking new, is bound to encounter less trouble but in the long run, you’ll have to do your own share of maintenance. Don’t worry, this is the “only maintenance” that Optima batteries require and you will need to comply if you want to make sure that you get the best out of your Optima. Cleaning is very easy. In fact, you don’t need a commercial cleaner to do it. You can use a solution of baking soda and water. Using a steel brush, scrub off the tops carefully before you charge. The corrosion can cause slow and mediocre charging.

    Know when to replace. Optima batteries may be among the best in the market but you’ll also have to accept the fact they have a shelf life. On the average, they last for more than five years, that is, if you have been properly charging Optima battery all your life.

    Charging Optima battery is quick and easy. Simply follow this guide and make the most out of your battery. If you need some advice, you can always seek help from your mechanic.

    And Optima batteries are good why? They don't seem like good value for money to me.

    I hope it is something to do with my charging system, I read a lot of reviews before buying my yellow top, my other concern is I bought it from Repco, no idea how long they had it on the shelf, not even sure if that would matter.

    solid, reliable, long lasting, can recover from deep drains (like 4 volts)

    As to OP question about what is the best battery for single set up, you might want to read what defender2.net user tatra805 has to say in below thread. Quite educational and rational I think.
    Defender2 - View topic - Varta AGM G14 or Optima Yellow Top battery?

    Maybe there is something wrong with my system but I think the $350 I spent on the yellow top could have been better spent.

    So I would not buy another unless I find something else is wrong other than the battery.
    Pat if the system is new there is definitely something wrong there. DO NOT drain your battery to 11.5v again if possible or you will be up for another well before it's due. Check with Sidewinder about the set up. One wire in the wrong spot can be all it takes. It could be an earth issue as well. Of course, the battery may well be faulty as well. It may have come supplied broken. Probably not likely but can happen.

    Agree that there seems to be a charging issue, but 80% DOD is not going to hurt a deep cycle Optima (though it will certainly give non-deep cycle bats something to think about) - it's one of the things they're designed for.

    I have had a blue top in my tinny for about 2 years now and it gets a real pounding especially in a small chop, have drained it down to about 10V more than a few times. So far seems to be coping fine, 2 years is on the long side for a battery in my boat, so I am more than happy with the Optima.
