Note: Not all controls are available on all models.
Charge Rate Selector Switch
Use the Charge Rate selector switch to select the charge rate or engine
starting setting you require.
2A Slow Charge Rate• – Intended for charging small batteries such as
those commonly used in garden tractors, snow mobiles and motorcycles.
10A, 15A, 20A, 30A Fast and 35A, 40A, 44A, 50A, 60A, 80A Rapid •
Charge Rate – Use for charging automotive, marine and deep-cycle
batteries. Not intended for industrial applications.
100A, 125A, 180A, 200A, 225A, 300A Engine Start• – Provides 100, 125,
180, 200, 225 or 300 amps for cranking an engine with a weak or run down
battery. Always use in combination with a battery.
Timer (Not applicable for model SE-2352)
Timer Setting• :Thetimerallowsyoutosetaspeciedtimeforcharging.
After the timer expires, the charger stops charging your battery. The main
function of the timer is to prevent over charging while allowing a battery
time to obtain a satisfactory charge. To properly set the timer, you must
know the size of the battery in ampere hours or reserve capacity in minutes
and the state of charge. It is important that you determine the appropriate
stateofchargeofyourbatteryasspeciedinSection12andsetthetimer
accordingly.
Hold• : This position defeats the timer function, allowing for continuous
operation. Be sure to monitor the charging progress and stop it when the
battery is charged. Not doing so may cause damage to your battery or may
cause other personal property damage or personal injury.
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.
Percent of Charge•
The percent of charge scale is intended as a visual aid to help simplify
reading the state of charge. The percent of charge is based on the current
drawn by the battery. For this reason, accuracy will vary with the size and
battery type. This means that the indication for a fully charged large battery
may be slightly less than 100%.
Model SE-2352 employs 2 toggle switches:
Switch #1• - Use this switch to select the 200 Amp Engine Start and the 35
Amp Charge Rate. Switch #2 must be in the down position (Select Position)
when using Switch #1.
Switch #2 - Use this switch to select the 2 amp Charge Rate and the OFF •
position. Also, use to select use of Switch #1. Note that Switch #1 is only
effective when Switch #2 is set to “Select Position.”
Battery Load Tester Switch (Model SE-8050 only)
When testing a battery, use this switch to apply a load to it.
