What buyers say about Mighty Max Battery ML18-12 - 12V 18AH CB19-12 SLA AGM Rechargeable Deep Cycle Replacement Battery
After using a DC plug and a port on the charge controller to charge my cell phone, the battery fell to 12.6v and the solar panels charged it back up in a matter of minutes.
I was looking for a battery that would last me 3 years on my kayak, and the one I received was in good condition even though I initially had doubts about packaging.
The solar charger was useless as we were in the woods and it was difficult to charge it through a charge controller.
Will this battery last as long as the original did? Only time will tell, and I will state that the cost for this battery, $38.89, is a whole lot better than the $64.99+ that I saw for the replacement battery from "other" places.
It is still perfect two years later, and I would recommend it to anyone looking for a clay thrower.

18 AH 2 fans consuming 6 Amp each would run a little over an hour.
