CHARGING ALGORITHMS

Almost every model of battery has different charging requirements and each application may add to those
requirements. Delta-Q Technologies has established over 200 charge algorithms for the most common motive
deep cycle batteries. These algorithms are designed to get the longest battery life and meet a variety of
application environments.
The algorithms are specific to each manufacturer and model of battery. Your equipment supplier or charger
distributor is responsible for ensuring the active charge algorithm matches the battery pack charging requirements.
Contact them with questions regarding the default algorithm, the other algorithms on the charger, and which
algorithm to select for each battery pack.

Displaying the Active Algorithm

There are up to 25 charge algorithms stored in the charger. Use the Charger button to display and/or change the
active charge algorithm.
Press and release the Charger button to display the active algorithm. It will be displayed twice on the GREEN LED.
(e.g., Show Active Charge Algorithm 21).

Selecting a Charge Algorithm

1. Activating Charge Algorithm Select Mode
Press and hold the Charger button until the GREEN and RED LEDs start flashing fast indicating Select Mode is
now active. The BLUE LED (AC) remains ON during this process. Once the GREEN and RED LEDs stop flashing, the
GREEN LED will flash slowly displaying the first algorithm available in the list to be selected. In this example,
Charge Algorithm 21 is the first stored algorithm. Then, the GREEN and RED LEDs flash fast again indicating the
algorithm will be displayed for the second time.
Note: If there is no user interaction, the charger will exit Select Mode five (5) seconds after displaying the
algorithm for the second time.
