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.
All RC chargers have charging algorithms even if the charger does not have a UI. 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 for
information on selecting and/or changing the charging algorithm or any 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.
Follow these steps to identify the default algorithm on a charger with a user interface:
1. Press and release the Charger button to display the current charging algorithm. The charger
displays its default algorithm. Algorithms are indicated by the number of consecutive flashes.
This is repeated twice.
Algorithm 7 =
Algorithm 7 = RED flashes Green Green Green Green Green Green Green
2. Algorithms in the double digits display in the same way: by one or more flashes, a pause, then
one or more flashes. This is repeated twice.
Algorithm 33 = ||
Algorithm 33 = RED Flashes Green Green Green || Green Green Green).

Algorithm 33 = RED flashes Yellow Yellow Yellow || Yellow Yellow Yellow)
3. To display the next algorithm, press the Charger button anytime during the four cycles. Where
the above pattern commences with the new algorithm. If there is only one algorithm on the
charger, the old algorithm is still indicated.
4. When your desired algorithm is flashing, press the Charger button for seven (7) seconds to
select the new algorithm. The new algorithm selected is displayed in green. This will be repeated
for two cycles with red flashes in the middle to indicate end of a cycle.
Algorithm 7 =
Algorithm 7 = Green Green Green Green Green Green Green
If the Charger button press is dropped before seven (7) seconds, the LED reverts to displaying the
last algorithm in amber to signify the button was released and the algorithm was not programmed.
5. Press the Charger button to check the desired algorithm has been selected.
