"The truth is that any lead acid battery, be it a Gel Cell, AGM or flooded batteries such as DCBs, should be cut-off at 11.6 volts. Not doing so increases the risk of damage to the battery and if taken down deep enough into the batteries charge, will ruin the battery."
The term Cut-off Voltage is activated voltage level at which the charge controller ( a voltage and/or current regulator) disconnects the load from the battery. The battery''s cut-off voltage is determined by the manufacturer, so …
Battery vendors typically specify fully discharged at about 1.95V per cell (11.6V for a 12V battery). The loaded vs. non-loaded battery voltage can easily vary by 0.5-1V. For example if I set the threshold to 11.6V (loaded), when isolated the battery voltage jumps up to 12.1V, however if I set...
