Battery Charger Status Lights

The operating status of the Battery Tender battery charger is indicated by an amber status light and a green status light.

If neither light is lit, then the battery is not properly connected and/or the charger is not plugged into AC power
.

The following describes the status corresponding to each light pattern:

RED LIGHT FLASHING – The red light flashing indicates that the

battery charger has AC power available and that the

microprocessor is functioning properly. If the red light continues to

flash, then either the battery voltage is too low (less than 3 volts) or

the output alligator clips or ring terminals are not connected

correctly.

RED LIGHT ON STEADY – Whenever the red light is on steady, a

battery is connected properly and the charger is charging the

battery. The red light will remain on until the charger completes the

charging stage.

GREEN LIGHT FLASHING – When the green light is flashing, and

the red light is on, the battery is greater than 80% charged and

may be removed from the charger and used if necessary.

Whenever possible, leave the battery on charge until the green

light is solid.

GREEN LIGHT ON STEADY – When the green light stops flashing

and burns steady, the charge is complete and the battery can be

returned to service if necessary. It can also stay connected to

maintain the battery for an indefinite period of time
