Product Description
L.E.D Battery Indicator/Tester for any of the Waverunner ranger of Bait Boats As you'll see from the pictures this ideal device can either be plugged in to the rear socket of your boat or direct in to your battery lead (new type only) .
Very simple to operate, displays four L.E.D bulbs in traffic lights Red, Yellow & Green.
Works like this:
Yellow (4) = 13 volts (Very Maximum Charged)
Green (3) = 12.5 volts (Fully Charged) Yellow (2) = 12 volts (Low)
Red (1) = Below 12 volts (Need Charging)
They work like a traffic light system, when all lit battery is fine. As each one goes out the battery is getting weaker. When its just the red light on, your batteries need charging.
