Red and Greenish Triangles
The image above relates to a charger with two charging rates, two amp and 12 amp.
12 Amp Charging Current:
The big red triangle shows the amount of current (amps) flowing from the charger to the battery. Equally it charges the battery, the flow rate decreases. The needle moves to the left, and into the green surface area. When the bombardment is fully charged it will betoken around vi amps.
2 Amp Charging Current:
The small-scale red triangle shows the amps flowing on the two amp setting. Again, the needle moves to the left as the bombardment becomes charged.
