[QUOTE="westatrest, post: 27346, member: 1137"] you can Guesstimate how much run time you will get from a battery and pump, by knowing the current draw of the pump and the amp/hour rating of the battery. basically a pump drawing 5 amps on full load, would theoretically run on a 20Ah (amp-hour) battery for 4 hours..but keep in mind, as the battery looses its stored energy, the voltage (12v) will also be lost therefore as the supply voltage drops below the rated voltage of the pump, to do the same amount of work it will draw more current, and flatten the battery quickly! this will all depend on the running condition of the pump, the condition of the battery, the ambient temp (batteries do not like the cold!).. so in summary, its anyones guess how much run time you will get, but I hope this helps to make an informed decision as to how big a battery you might need [/QUOTE]
