BC5500B Operating Instructions
Battery Charging Procedure
1. Perform visual inspection of battery(ies) before charging
to help prevent personal injury and property damage.
Check the following conditions, correcting defects and/or
replacing battery(ies) and components as required.
— Cracked case.
— Improper electrolyte level - fill to level specified by
battery manufacturer.
— Frozen electrolyte or resulting damage.
— Loose or corroded terminal/cable connection.
— Frayed or broken cables.
— Loose or over-tightened battery hold-down.
— Correct size and capacity for vehicle.
2. Set the Coarse Rate or Fine Rate switch. Determine
battery voltage from vehicle owner's manual or battery
instructions. Use:
— 6LO or 6HI (6 volt battery),
— 12LO or 12HI (12 volt battery),
— LO (Charges at a low voltage. Useful for extended
charging or finish charging on any lead/acid battery.),
— 2 REG (Charges at a slightly increased voltage. To
be used for regular lead/acid or conventional
batteries.),
— 3 HYBRID (Charges at a higher voltage. Select this
setting for batteries that use combinations of lead
antimony on positive plates and calcium lead on
negative plates. Hybrid batteries use porous plates
saturated with electrolyte and fiberglass plate
separators. These "recombination" batteries are sold
under such brand names as Chloride's Torque
Starter and GNB's Cathanode.), or
— HI MAINT FREE (Charges at the highest voltage
needed for the "maintenance-free" battery types.
These are typically calcium grid type internal
construction batteries such as the Delco Freedom
batteries.).
3. Measure and record battery state of charge.
— Specific gravity.
— Open circuit voltage.

State of charge is used in step 9 to determine
charge time.
4. Verify AC power cord is disconnected from outlet and
Length of Charge Timer is set to OFF.
