Can I use auto battery to power sump pump?

Question

How long would it last with DC sump pump? How do I recharge my battery? Anyone know any good DC sump pump?

Answer 1

yes there is a 12 v sump pump on the market, think sears has them, then put a  110v trickel charger on it, or if theres no power, use a solar charger, [harborfreight.com]

Answer 2

I really have no clue, but the Q is curious. I have never heard of a DC sump pump, most especially never heard of a car battery used in that manner. Beyond that, to keep the battery charged you'd have to use AC anyway, and a charger.

  Beyond, beyond that, I cannot imagine a 12 volt system being very effective as a sump pump. Certainly you might find a converter to operate DC appliances from the 12 volt, but the entire notion seems a bit much to me.

  I do wish you success however.
