Operating The Freedom SW 3000
When batteries are cold, their chemical reaction is sluggish, meaning they
don’t absorb charge as easily. Thus a charge level optimized for room
temperature will not charge the batteries sufficiently if they are cold. The
charger must compensate by increasing its voltage to achieve the
compensated equivalent of a room temperature charge. If the batteries are
hot, the chemical reaction is hyperactive and they absorb energy too easily;
thus a standard room-temperature charge would tend to overcharge a hot
battery. Therefore, the charger compensates by reducing its voltage.
The BTS automatically, and in real time, makes adjustments to the
charger’s voltage setpoints to properly charge your batteries. The actual
charge compensation formula can be found on “Charger Specifications” on
page 61.
If a BTS is not present, the Freedom SW 3000 uses the hot setting, the
default value, unless the setting has been adjusted during configuration.
Charging may not be effective at extreme temperatures. See “Charger
Specifications” on page 61.
Operating in Equalization Mode
NOTES:
•
Equalize mode is automatically disabled if you have selected “Gel” or
“AGM” as the battery type.
•
As a general rule, do not equalize a lead-acid battery unless there are
provisions to add water to it and the manufacturer recommends
equalization.
IMPORTANT: It is normal to see a voltage that is different than the
specified setpoint when charging if the battery case temperature is above or
below 77 °F (25 °C).
EXPOSURE TO CHEMICALS AND GASES HAZARD
•
Make sure the area around the battery is well ventilated.
•
Equalization generates explosive gases.
Failure to follow these instructions can result in death or serious
injury.
RISK OF DAMAGE TO BATTERIES
•
Do not equalize sealed lead-acid batteries and gel batteries.
•
Only flooded (wet) lead-acid batteries should be equalized.
•
Never equalize a lead-acid battery more than necessary. Always
check the electrolyte level before AND after equalization. Fill with
distilled water per the battery manufacturer’s recommendation.
Failure to follow these instructions can damage the unit and/or
damage other equipment.
