I remember from chemistry that you always read volume in a graduated cylinder at the bottom of the meniscus. But what about the hydrometer? Just got to thinking about it today when I was checking the ...

The 1st one they were convinced that the varnish dip had air bubbles around the windings and causing heat problems. This one is WAY better and doesn't dip into failsafe, but it still gets hot
The "lost" amp hour capacity in an absorbed glass mat battery is exactly why the battery can survive "100%" discharges, resist freezing while barely having a charge and a a whole host of other attributes that separates the battery from flooded lead acid batteries. I had the old Trace 2500SB charging at it's maximum rated 120-amperes at 12-volts plenty of times without smelling like Mount Krakatoa. I wonder what's different about the Magnum?
