find out the amps your pump uses and i will tell you

[mci services]

heres an example to work it out

85 ah battery

1 deduct 10% from the 85 =76.5
2 divide 76.5 by the amp of the pump so if its 7 amp 76.5/7=10.9

so you would get 10.9 hours continual use

its probably 7amps or thereabouts so you should get 10 to 11 hours. if you look at the pump it will say on the pump what the amps are

i use a 110 leisure battery, lasts over a week before it needs re charging

[dmlservices]

your battery's will last longer if you don't deep cycle them, i use 2-75 ah battery's and rotate them .
