UNDERSTANDING CHARGE RATE TIMES
The built-in intelligent micro-processor will continuously monitor and adjust the charger to provide a fast,
safe and efficient charge. Note that battery charge times will vary depending on several factors including:
• Battery State
If a battery has been only slightly discharged, it can be charged in less than a few hours.
This same battery could take up to 10 hours if very discharged.
• Battery Rating
A higher rated battery will take longer to charge than a lower rated battery under the same
conditions. A battery is rated in ampere-hours (Ah), reserve capacity (RC), and cold-cranking amps (CCA).
• Charge Rate
The charge rate is measured in amps. A battery charged at a lower rate will take longer
than a battery charged at a higher rate. However, smaller batteries can be easily damaged by charging
at a rate which is too high for the capacity of the battery.
• Temperature
Cold temperatures will affect a battery’s ability to accept a charge. Charging in cold
temperatures will increase the amount of time required to charge a battery.
OTHER FEATURES
MAINTENANCE MODE
When the green 100% LED is lit, the charger has started Maintain Mode. In this mode, the charger keeps the battery
fully charged by delivering a small current when necessary. If the charger has to provide its maximum maintain
current for a continuous 12 hour period, it will go into Abort mode. This is usually caused by a drain on the battery
or the battery could be bad. Make sure there are no loads on the battery. If there are, remove them. If there are
none, have the battery checked or replaced.
INLINE FUSES
Inline fuses, located close to the ends of the red leads, protect the charger from extremely high voltage surges,
lightning strikes or other high-current surges. If a fuse blows, replace only with an ATC-30 30A 32V blade fuse.
MAINTENANCE
•
Clean the ring terminals any time you need to remove them (no need to remove, if permanently mounted).
Wipe off any battery fluid that may have come in contact with them, to prevent corrosion.
•
Occasionally cleaning the case of the charger with a soft cloth will keep the finish shiny and help prevent
corrosion.
•
Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage
to the cords and charger.
•
Store the charger unplugged from the AC power outlet in an upright position.
•
Store inside, in a cool, dry place. Store the ring terminals in a way that will not cause damage.
