Time Required To Charge A Battery; Working With A Dead Battery Or A Battery With A Very Low Voltage - WeatherTech BatteryCharger Manual Del Usuario

TIME REQUIRED TO CHARGE A BATTERY:

The WeatherTech ® BatteryCharger part number 022-0200 charges at a rate of 1.25 Amps
or 1.25 Amp-hours per hour. Therefore, a fully discharged 15 Amp-Hour battery will take
approximately 9/ hours to recharge to 80% capacity.
The WeatherTech ® BatteryCharger part number 022-0209 charges at a rate of 4 Amps or 4.0
Amp-hours per hour. Therefore, a fully discharged 15 Amp-Hour battery will take approximately
3 hours to recharge to 80% capacity.

WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY LOW VOLTAGE:

If you try to charge a dead battery having a voltage below 2 volts from a Flooded/AGM battery
or 4 volts from a Lithium Iron Phosphate battery, WeatherTech ® BatteryCharger will not start. An
internal safety circuit prevents the charger from generating any output voltage unless it senses
at least 2 volts from a Flooded/AGM battery or 4 volts from a Lithium Iron Phosphate battery
at the charger output. In this situation, the amber LED will continue to flash, indicating that a
charge has not been initiated.
NOTE:
If a 12 Volt, Lead-Acid battery has an output voltage of less than 9 volts when it is at rest, when
it is neither being charged nor supplying electrical current to an external load, there is a good
chance that the battery is defective. As a frame of reference, a fully charged 12-Volt, Lead-Acid
battery will have a rest-state, no-load voltage of approximately 12.9 volts. A fully discharged 12-
Volt, Lead-Acid battery will have a rest-state, no-load voltage of approximately 11.4 volts. That
means that a voltage change of only 1.5 volts represents the full range of charge 0% to 100%
on a 12-Volt, Lead-Acid battery. Depending on the manufacturer, and the age of the battery,
the specific voltages will vary by a few tenths of a volt, but the 1.5-volt range will still be a good
indicator of the battery charge %.
STATUS INDICATING LIGHT: If the light is not lit, then the battery is not properly
connected and/or the charger is not plugged into AC power . The following describes light
operation:
< AMBER LIGHT FLASHING (Amber LED 1) - The amber LED flashing indicates that
the battery charger has AC power available and that the microprocessor is functioning
properly. If the amber LED continues to flash, then either the battery voltage is too low
(less than 2 volts for a Flooded/AGM battery or 4 volts for a Lithium Iron Phosphate
battery) or the output alligator clips or ring terminals are not connected correctly.
< ALTERNATING GREEN/AMBER (Amber LED 1 & Green LED 5) This indicates the
battery charger has gone over the time limit while in the Battery Recovery Mode (see
page 5 for complete explanation). Also Reverse polarity connection to the battery.
< AMBER LIGHT ON STEADY (Amber LED 1) - Whenever the amber LED is on
steady, a battery is connected properly and the charger is charging the battery. The
amber LED will remain on until the charger completes the charging stage.
< GREEN LIGHT FLASHING (Green LED 5) - When the green LED is flashing and the
amber LED (Amber LED 1) is solid the battery is greater than 80% charged and may
be removed from the charger and used if necessary. Whenever possible, leave the
battery on charge until the green light is solid.
< GREEN LIGHT ON STEADY (Green LED 5) - When the green LED burns steady, the
charge is complete and the battery can be returned to service if necessary. It can also
stay connected to maintain the battery for an indefinite period of time.
