Does your generator start from deep cycle house batteries OR dual purpose house batteries?

Id get dual purpose, deep cycle batteries don't provide high cranking amps needed to start a motor, they are good just for low current/amp consumption over a period of time. like running lights, and a TV etc. The dual purpose can do both starting and run 12v accessories, 120v through an inverter too.

Short answer yes.. The generator starts off the house batteries, the starting draw of the genny is fairly low.. in fact once when I accidently killed both house and chassis batteries and thus had nothing left to crank her up with I dug out one of the garden tractor batteries I used on my wife's scooter. these very small batteries are like less than 10% of the house batteries. And it fired right up and held till the transfer switch kicked in and the PD9180 began providing power.. So it really does not matter. to a pair of GC2's (230 amp hours) the starting demand of the generator.. Is less than what a golf car would need to move you to the next T.

Mine's a dual purpose because only a group 24 will fit in the compartment so there aren't any deep cycle options. If one would fit, I would use a deep cycle battery. Any deep cycle will start a generator just fine. The little motors don't take that much current to turn them over.

Like others said,it doesn't take much battery to start a generator and a duel purpose battery is fine, true deep cycle batteries will normally last a lot longer .
