They do, and they do, and they do.


They're called "deep-cycle" batteries, or "marine", or sometimes "golf
cart" batteries.


** The first two have similar peak current ability to a normal car
attery - at significantly higher cost.

The third is usually the SLA type, with slightly reduced peak capacity and
hugely higher cost.

Please don't mislead the children.


** A crime that did not happen.

Even if such batteries exist, they won't have a cost-effectiveness
advantage over car batteries. You are thinking that by trading in
peak current you are going to gain in overall amp-hours. It just
isn't true. You won't find a cheaper way to store X amp-hours than a
car battery.

Deepcycles have lower lifecycle cost if the battery is significantly
discharged. Car batteries won't tolerate much of that, deepcycle
batteries are designed for it. That's why RV's and bassboats use
deepcycle batteries!

Nominal voltage is 13.8 fully charged. "12V" is just the sticker value.

Nominal voltage is 12.8 volts when fully charged, if it's not being
tricklecharged at the time. It goes down to about 12.0 volts when
discharged. Both of these depend on temperature.
