I have an RV setup of 2, 12V battery banks. The first consist of 2, 12V car batteries in parallel supplying a 1000w inverter. The second is 2 deep cycle marine 12V batteries in parallel supplying a 2000w inverter. I use two 100w solar panels to keep both banks charged. I recently purchased a Schumacher SE-1250 charger to start providing equalizer charges to the batteries. I have generated a tracker for measuring each cell temp and SG during the normal charging phase (10A) and for the EQ phase (30A). Each bank took about 12 hours to complete, 6 hours per battery. 5 hours at 10A and 1hour at 30A with readings every 30 mins for each cell. My plan is to do this quarterly to generate sufficient data to determine if I need to increase or decrease the EQ phase.
Detection of variations in the relative velocities of the primary and secondary seismic waves – expressed as Vp/Vs – as they passed through a certain zone was the basis for predicting the 1973 Blue Mountain Lake (NY) and 1974 Riverside (CA) quake.  Although these predictions were informal and even trivial, their apparent success was seen as confirmation of both dilatancy and the existence of a preparatory process, leading to what were subsequently called "wildly over-optimistic statements"  that successful earthquake prediction "appears to be on the verge of practical reality."
