How
it works
• Top-up partially charged batteries.
• Serves as a fast-charger.
The time required may vary depending on the battery
type. At a C-Rate of 1C, the charge time is:
NiCd
90 minutes typically
NiMH
3 hours typically
SLA
10 hours typically.
For more information on C-Rates, refer to CHAPTER 11
- C-CODE TABLES.
CHARGE fully charges a battery. After full charge is
reached, trickle charge is applied to maintain full charge
capacity. Full charge is detected by the Negative Slope
method. Poorly matched cells that do not produce an
adequate slope are timed out by the Plateau Timer. The
combination of these two methods provides an accurate
and safe means to terminate the fast-charge. No
temperature sensing is required if the battery is serviced
within the recommended temperature range.

Partially or fully charged
The analyzer recognizes a partially or fully charged
batteries
battery. On these batteries, the charge time is
shortened accordingly. A shorter charge time also
applies to batteries that have a low capacity.
Reverse Load Charge
Reverse Load Charge is used to promote the
Method
recombination of gases generated during the fast-
charge of the NiCd and NiMH batteries. The Reverse
Load Charge intersperses discharge currents between
the charge pulses. The results are a cooler and more
effective charge than conventional
chargers. In addition,
the "memory" phenomenon is reduced as the battery is
stimulated while charging. Refer to "4. Auto" for
definition of memory.
Note Reverse Load Charge is used for all charge and
trickle charge functions .
