Net accepted current less than 1.5% of Ah capacity = ✓.Rule #1 for most tradittional Ah counters:ĭisable the “ auto-sync” feature and use manual “ known-full” re-sets. When not properly installed, and kept well calibrated, Ah counters can be horribly inaccurate… WHEN PROPERLY CALIBRATED – About 98% of Ah counters I come across are NOT properly calibrated/programmed.
