Below are our standard thresholds, recommended for all 12v lead-acid battery systems including an alternator or other charger. Completely bespoke thresholds and output patterns can be created for you at no extra cost (e.g. for custom or ultra-low power applications).


Interpretation:
Voltage: Output: Engine running: Engine stopped (electrics off):
>15.20v Green / Red alternating over-charging – regulator problem not applicable
>13.20v Green steady normal charging exceptional battery charge (uncommon)
>12.45v Amber steady under-charging – alternator problem normal battery, charged and in good health
>12.25v ■■ Red slow flashing not charging – battery low fair battery charge
>12.05v •• Red 2 flashes, repeating not charging – battery low low battery charge
>11.80v ••• Red 3 flashes, repeating not charging – battery very low very low battery charge
<11.80v •••• Red 4 flashes, repeating not charging – battery very low consider renewing battery

* this table reflects a monitor correctly installed as per the instruction guide, and not connected to a high load circuit
(e.g. headlights)
** a very small number of users confuse the amber and red colours. However, amber is always steady, reds are always flashing
