sixwheeledbeast Posted August 2, 2015 Posted August 2, 2015 get yourself a grand total which should not exceed 75% of the total capacity. Trade installers would actually measure these currents rather than rely on the specs leaflets, but that's another matter. 75%? 12 hours standby with an activation. Quote
charlie6 Posted August 3, 2015 Posted August 3, 2015 Hi, that's 75% of total capacity, he could go a bit higher though since the calculation is intended to ensure no overload whatsoever, I know I have in some circumstances. Ideally aim for the longest standby possible, during my last trouble shooting excursion I found a duff 2.1 battery where the occupants were frequently abroad...changed for 7ah added psu with a further 7ah. I think it worked out at a few days standby..can't remember exactly. Quote

sixwheeledbeast Posted August 4, 2015 Posted August 4, 2015 Quiescent or Active ? 12 hours standby, so Quiescent. Quote
