Properly reading a battery hydrometer
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 Magnum alone can deliver about 105A but that can take the transformer above 200F pretty quickly before I start smelling varnish. But as Niner can attest, access to these batteries for fluid check requires removal of the front two to get to the rear two, that's why he's trying to talk me into AGM :)
Hi Jeff,
A footprint that does 115 amp-hours for flooded yields about 105 amp-hours in AGM. However the AGM does charge faster and voltage support is somewhat better. The path forward may be to LI chemistries and right now cycle life cost is pretty much identical to AGM. Flooded is still the price king.SCVJeff wrote:
As for AGM's I don't think I can get the same capacity in the same footprint.
