OK partially discharged. But the same partially discharged loevel cheap starter battery wouldnt even turn it!
If you leave your lights on all night and then remove the battery it still reads 11.5 or so volts. It never gets completely flat precicely because the internal resistance goes up as state of charge goes down, Effectively you need to short it out for long periods to do this completely discharged thing which doesent happen in practice.
Thats why a disconnected optima or hawker battery will still start a car after a year plus. A cheapy wont after 3 months usually because they typically lose MUCH more through internal losses. Regardless of what you claim...
Nominally flat in the battery industry refers to a reading of 11.8 to 12.1 depending on battery type. Thats has in the case of a low resistance hawker or optima still got the amp capability to start your car. The cheapy still has same capacity left but its not accessible unless you take it out slowly with say a small bulb.
An optima can start a car when say 5 percent residual charge remains because it suffers far less from the internal resistance dropping since its so damned low to begin with. Its typically half what a cheap 12v starter battery is so can deliver double the current (CCA) and suffers half the voltage drop.
A starter only cheap battery would struggle to start a car (depending on car/temperature obviously) when its at 50 percent discharged. This is what I am trying to convey that you just dont get.
Yes it is. It reveals much the same.
Sorry but sales blurb has nothing technical in it. This is actual facts that you dont like. And why does price have anything to do with it?
You claimed they were a con and no better. Well you are completely wrong!
You mean like Astom Martin? Or Hummers or many us vehicles? No I dont. Its one of cost. Not everybody cares about that though. The quality remains long after the price is forgotten
Actually I am not.
Wrong. Of course it depends on what special storage conditions you have in mind, but mostly wrong. Unless you have an oversized battery where the internal resistance decrease wouldnt be a factor. In which case the optima would probably start it after 2...
Cheap means all the ones you are talking about. You are the one saying all the decent ones are too expensive. Optimas are competitively priced against equivelent batteries like the Hawker AGM batteries.
Why no real facts to explain why I am "wrong"???
Sorry but they are simply better. Simple tests prove it. You cant admit that because you would lose face, which you seem to be doing pretty well anyway but I am wasting my time on you.
