Has anyone replaced the battery on a 15KW ultrasource? If so what battery did you get and where did you get it. Can't find anything online that matches orginal one.

Thanks

I haven't found an aftermarket replacement YET!!!. Wish I could remember the name of the company that is supplying the batteries to generac. I called them several months ago and they had orders for at least 300. Asked me if I wanted to go ahead and order and wait who knows how long. If you get a moment could you post the brand and all ampere hour info. It would be quicker to refresh my memory than trying to find my notes.

CCA 300

There was also a number on top of the label

If you find a replacement, please post back the name brand and model number.

According to the owners manual that battrey is a U-1 available at lawn and garden stores, auto parts stores just about anywhere lead acid battreies are sold even Sears.

U1 is the battery classification size. The cheapest lead acid wet cell 12 vdc is napa # BAT8221 EPM batteries are classified as a sealed battery and cost a lot more. The other battery I was trying to cross was for the 8500 watt model generac. Those are the goofy size batteries that are still on back order. In the smaller portables you should really use a sealed battery to keep the corrosion out of places where it doesnot need to be. When a unit is running you would not want to suck acid fumes into the back of the gen end thus setting up a corrosive environment in the gen end leading to a premature failure. Just a thought to keep in mind.
