*Amperage is only present when the unit is
connected to a battery or in START mode.
Ammeter:
The ammeter indicates amount of current measured
in amperes that is drawn from battery.
For example, in 40 amp charge rate a typical discharged
battery will initially draw approximately 40 amps.
As battery continues to charge, current will taper to
15 to 20 amps at full charge. When cranking an engine,
starter motor draws up to 50 amps. The meter needle
will register to extreme left side during 2 amp charge
rate, indicating minimal activity because the meter
doesn't have the resolution to display such low rates.
When a battery is close to being dead or has a
very low charge, it will want to draw more current.
When a dead or low battery is charged, the charger's
ammeter will register at high end. As the battery charges,
the reading will move down toward the low end,
resting on zero when battery is fully charged.
Do not depend on reading ammeter to approximate
how long charging will take. Even at full charge,
ammeter will still provide as much as 50% of charger's
output rating. Sometimes conditions such as a cold
battery, a sulfated battery, or a deeply discharged
Lead Calcium battery may cause ammeter to read near
a full charge when charging process is only beginning.
Note: The ammeter shows the amount of current being
drawn from the charger. It does not show what the
charger is capable of delivering. When the battery is
fully charged and registering zero on the ammeter,
a small charge will continue to move from the charger
to the battery. If the charger is not disconnected
from the battery, eventually heat build up will
cause the battery acid to boil and damage the battery.
Monitor battery charging progress constantly and
if battery gets warm, stop charging it immediately.
