I don't care about the screwy31 anymore. My screwy schumacher starts on its own and does what it wants to it when I turn on a power strip, unless I decide to press some of its buttons and thereby exert some minor control over its expected insanity.
I got nearly 500 cycles from it before removing it from my rig, most recharges from solar. Yes it wasted energy to get back to full. Not using a generator, I don't care.
Now the screwy31 simply takes some load off my workshop circuit when powering hi amp AC tools, powering 12v led lights and fans, which also were removed from rv for their more powerful later models.
Between a lifeline and a northstar in my intended dual purpose usage where superhigh CCA is enjoyed and utilized, I might again go for the Northstar, perhaps a 31 instead of a 27.
But perhaps the lifeline could spin the engine just as fast when well depleted, and last more total cycles. Without actual data that would be a guess, edu mun cated or not.
