This information is communicated to the charger by the battery and is incorporated,
through specialized programming and algorithms to optimize the charging of the
DIGITAL battery.
IMPORTANT: Due to the specialized communications between the charger and the
battery, batteries without the Logic Series construction and
communication capability (manufactured by Anton/Bauer before
1989 as well as so-called “rebuilds”) can not be charged with this
TWIN. The InterActive communication of Logic Series batteries is
the key which allows the TWIN to safely identify and address new
style and chemistry batteries as they are developed. Moreover, this
communication ensures that batteries contain the quality cells,
workmanship and safety of genuine Anton/Bauer products. If non-
Logic Series batteries are placed on the TWIN, the red and green
LED indicators will flash alternately. This indication means that the
battery cannot communicate its identity to the TWIN and is not
charging.
Three Stage Charging Methodology In general, the TWIN will deliver a three stage charge routine to each battery.
1. Stage One will deliver a charge matched to the capabilities of the battery. During
this stage, six separate cutoff methods are in operation, simultaneously, ensuring
the fastest, safest charge for that battery:
TCO - Temperature cutoff that stops the Stage one charge precisely when a
temperature indicative of full charge is reached;
Dt/dT - a microprocessor based algorithm that measures 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;
-ΔV - a method to determine the end of stage one charging by identifying a
characteristic “reverse slope” of a Ni-Cd cell. Since this characteristic can
be disguised 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 Anton/Bauer Logic Series feature.
The charger determines the maximum charge time for the particular battery
and uses this information to ensure that overcharge conditions are avoided.
FUL - this determination is made when a fully charged DIGITAL battery is
returned to a TWIN 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.
