Custom Programs
Program
Charge/discharge the battery until the derived capacity
drops to below the set target setting.
Custom-Code
2121-0000-0000-0000:00
Phase
1 [2121] 2=charge; 1=discharge; 21 =if target capacity is
met, go-to Phase 1 (repeat as long as Target Capacity
is met; if it is not met, go-to the next Phase).
Phase
2-4
OOOO=OOOO-OOOO=skip to Exit Phase.
Exit Phase
[00] O=no cycle; O=done, no trickle charge.

Program
First, an experimental fast-charge is applied to evaluate
whether the battery will accept charge. If the discharge
that follows produces a capacity of more than 5%, the
battery is assumed fit for fast-charge and a number
of charge-discharge
cycles (prime) are applied until the
capacity reaches the maximum reading.
Prime a new or stored
battery A new battery, or one that has been in prolonged
storage, will often not accept a fast-charge.
Manufacturers
recommend a 16-to-24-hour trickle
charge prior to use. A prolonged trickle charge is often
not sufficient to prepare the battery for field use. The
battery should also be cycled (primed). Please note that
not all batteries behave the same.
•
If the initial fast-charge produces capacity readings of
5% or less, the battery is first trickle charged (Phase 4)
for approximately
16 hours, then primed (Phase 2).
Custom-Code
2134-2140-0012-4112:21
Phase
1 [2134] 2=fast-charge; 1=discharge; 34=if the capacity is
less than 5% (not ready to accept fast-charge), go-to
phase 4 for trickle-charge, or else go-to Phase 2.
Phase
2
[2140] 2=fast-charge; 1=discharge; 40=if the capacity
improvements (in comparison to the previous reading) is
less then 5%, go-to exit (it is assumed that the battery
has reached maximum capacity), or else go-to Phase 3.
Phase 3
[0012] OO=skip CC; 12=proceed back to Phase 2 to
repeat.
