I Live and learn. That's too danged hot in my opinion for temps in excess of 50F. These knotheads will do anything to boost apparent specifications to please the sales department. I am have been running 1.260 in my 2-volt cells.
The part that has hardened sulfation will always have low gravity and in turn really hampers CCA (biggest restriction = total limit of amperage). By establishing a "true" baseline for your gravity BFL13 I have a better picture of what's going on. The missing test link is a 20 hour test.
But, hey, if you flip the switch and the lights go on, what more can a person ask for?
