THREE STAGE CHARGING METHODOLOGY
In general, the Elora Battery Charging Cabinet will deliver
a Three Stage charge routine to each battery.
1. Stage One
will deliver a high rate charge matched to
the capabilities of the battery. During this stage, six sep
-
arate cutoff methods are in operation, simultaneously,
ensuring the fastest, safest charge for that battery:
CCO - This method requires the identification of the
particular battery size (capacity) and chemistry, an
exclusive Elora feature. The charger determines
the maximum charge time for the particular battery and
uses this information to ensure that overcharge condi-
tions are avoided.
STAGE ONE will deliver a charge matched to the capa-
bilities of the battery. During this stage, seven separate
cutoff methods are in operation, simultaneously, ensur-
ing the fastest, safest charge for that battery:
TCO - Temperature cutoff which stops the Stage one
charge precisely when a temperature indicative of full
charge is reached;
Dt/dT - A microprocessor based algorithm which mea -
sures a rise in temperature over a specific time, very
accurately indicating full charge. This method is also the
recommended method for charging Ni-MH technology;
charging by identifying a characteristic “reverse slope”
of a Ni-Cd cell. Since this characteristic can be dis-
guised by the age, temperature and the number of the
cells in a battery, it can never be employed alone;
CCO - This method requires the identification of the
particular battery size (capacity) and chemistry, an
exclusive Elora Logic Series
®
feature. The charger
determines the maximum charge time for the particular
battery and uses this information to ensure that over-
charge conditions are avoided.
FUL - This determination is made when a fully charged
DIGITAL battery is returned to a charger within specified
parameters of time, temperature, and battery voltage.
The DIGITAL battery communicates its fully charged
condition and the charger confirms the parameters and
immediately indicates a fully charged condition, without
additional verification.
TEMPERATURE COMPENSATED VCO – For HyTRON™
series of batteries. Similar to a VCO, however, only
operates within certain temperature parameters;
I-Min – for Dionic
®
batteries, a seventh cutoff method
is employed. The battery is charged to specific voltage
and I-Min current until full charge is reached. I-Min
is the “minimum current” flow required for proper cutoff
2. Stage Two
charging is a “balancing” or “stabilizing”
mode which calculates each battery pack type to offset
any imbalance of the battery’s cells, created by unequal
self-discharge or any capacity mismatch of the indi-
vidual cells in the pack. This stage can vary in duration
from zero to as much as 16 hours, depending on the
condition of the battery. The Stage Two charge for Elora
Series batteries reduces current automatically as the
battery charges maintaining the Lithium-ion cells at a
safe voltage level.
3. Stage Three
charging is the Elora exclusive
Lifesaver
®
maintenance mode. This patented pulse
routine keeps batteries fully charged, free from self-
discharge - indefinitely – without damaging heat associ-
ated with a so-called “trickle charge”. The Stage Three
programming for Elora monitors the self-discharge of
the battery, providing charge only when the battery
self-discharges to about 95% of its capacity.

NOTE: Batteries may be kept on a charger until ready for
use. The Lifesaver mode will keep them 100% charged.
NOTE: Elora recommends that each battery have
a charge position, for when the battery is not in use.
A battery can remain on an Elora charger indefinitely.
