• Percent of Charge
The percent of charge scale is intended as a visual aid to help simplify
reading the state of charge. It is scaled for use with the 6, 10, 12, 15 or
30 amp charge rate only. For the 2 amp charge rate use the triangle.
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. Typically a
28 ampere hour gel cell battery will draw less current at the end of the
charge cycle than a 140 ampere hour wet cell battery. This means that
the indication for a fully charged large battery may be slightly less than
100%.
Battery Type Switch
Three basic types of lead-acid batteries can be charged with these char-
gers. Use this button to set the type of battery to be charged. If you are not
sure of your battery type, use the Conventional setting.
• Conventional and Low Maintenance Batteries –
lead batteries. Conventional/Low Maintenance batteries require periodic
addition of water to the acid solution (electrolyte). Additional water may
be added by removing the filler caps located on the top of the battery.
When antimony is known to be one of the materials used in the battery's
construction, that battery is conventional/low maintenance type.
CAUTION: Some low maintenance batteries have a relatively smooth top
without any apparent battery filler caps. If, however, the battery manufac-
turer/distributor recommends periodic checking of the electrolyte level and
provides access to the battery for water additions, the battery is probably a
conventional/low maintenance type.
• Maintenance Free –
do not require water additions. Therefore, filler caps have been removed
from the battery surface. These batteries will have a smooth or sealed
appearance.
• Deep-Cycle – Deep-cycle batteries are usually marked as "Deep-Cycle"
or "Marine". Deep-cycle batteries are usually larger than the other types.
This type of battery has less instant energy but somewhat greater long-
term energy delivery than regular batteries. Deep cycle batteries have
thicker plates and can survive a number of discharge cycles.
Charge Rate Selector Switch (Voltage/Amp Selector)
Use this switch to set the maximum charge rate to one of the following.
• 2A Slow Charge Rate
those commonly used in garden tractors, snow mobiles and motorcycles.
The 2A rate can be used to warm or trickle charge larger batteries.
• 6A, 10A, 12A, 15A Fast and 30A Rapid Charge Rate
automotive, marine and deep-cycle batteries. Not intended for industrial
applications.
These are calcium/lead batteries. They normally
