I don't want to flood this thread about this, but when wiring in parallel, voltage is averaged (or stayed the same if the same voltage between sources) and current is added. When wiring in series, voltage is added, and current is averaged (or the same if the same amperage rating between sources).The AH rating on a battery is directly related to how much current that battery can provide total. Take a 700 CA battery for example. If you dont use 700 amps, it will maintain a voltage longer. AH is rated at 25 amps/hour. So if you only use 25 amps, of course it is going to maintain a decent voltage for longer. It only makes sence that if the AH doubles, so does that total amperage output of the battery. Refer to an electronics book about wiring sources if you have any further doubts.</blockquote>
