7. CHARGING A RECHARGEABLE BATTERY

Each set of Yellow and Green LEDs on the front of the charger are used to

indicate the charge status state for the channel associated with the set of LEDs.

Yellow/Green LEDs flash alternately – Charge failure on that channel

Multi-Stage Charge Algorithms

There are up to 8 charging Stages! Depending on the MODE selected, these

stages are already preset and implementation of each stage will vary from one

CHARGE MODE setting to the next, dependent on the type of battery intended to

be charged. These charge stages 'typically' include:

 PRE-QUALIFICATION-TEST Charge Stage:

 Tests Lead Acid battery for sulphation by applying a low-level charge current

and analyzes voltage and current values and rates of change to determine if

the battery is ready to transition to the next high-power Bulk Charge Stage.

 For Lithium cells, this stage is extremely brief and may not be annunciated. It

checks for minimum and maximum cell voltages. If a fully charged cell is

detected, a transition to 'Charge Complete' is done, bypassing all other

charge stages.

 BULK Charge Stage (also known as 'Constant-Current'):

 High Power charge, charges at a constant current or constant power rate to

deliver the 'bulk' of the charge needed

 Upon completion of this stage, approximately 80% of total charge is delivered

to the battery

 ABSORPTION Charge Stage (also known as 'Constant-Voltage'):

 Charge voltage is held at a constant level to optimize the amount of energy

the battery absorbs.

 Charge Amperage decreases as the energy is being absorbed.

 Termination of this stage occurs when the charge current decreases to a

preset value. Duration of this stage is dependent on many factors such as

size, type, age, and chemistry of battery.

 Upon completion of this stage, approximately 95% to 100% of total charge is

delivered to the battery.

 TOP-OFF Charge Stage (also known as 'Finish'):

 Charger charges at either a constant voltage, or constant current, or a

combination of constant-current / constant voltage to 'Top-Off' the charge in

a battery.

 This stage employs timing based on 'timers' measured and recorded during

previous charge stages, in combination with dv/dt and/or di/dt.
