*If the input rating of a charger is given in watts rather than in amperes, the
corresponding ampere rating is to be determined by dividing the wattage rating by
the voltage rating - for example:
1200 watts/120 volts = 10 amperes

Ammeter
The Ammeter indicates the amount of current, measured in amps, that is being
drawn by the battery. As a battery takes on a charge, it draws less current from
the charger. Correspondingly, the meter will show less current being drawn by
the battery. When the current stops decreasing, the battery is charged. The
start area of the meter indicates a high rate of current being drawn from the
charger. When cranking an engine, the meter needle will be at the extreme
right side of the start area. The 2 amp charge rate may indicate some activity
on the meter, although the meter does not have the resolution to display this
low rate. For the 2 amp charge rate, a triangle has been provided. Its accuracy
has been calibrated for use with small batteries.
