  1. Which charge profile (algorithm) should I use?

    Delta-Q has charge profiles optimized for a number of different battery types and Amp hour ranges for most major deep cycle battery manufacturers. The original equipment manufacturer (OEM) chooses the preloaded charge profile for their chargers and can provide information on the best charge profile for the batteries supported in their applications. Please contact the OEM for charge profile settings or a list of supported batteries.

  2. Where can I take my charger for service?

    Delta-Q is primarily an original equipment manufacturer (OEM) supplier and currently have no authorized repair center network for the chargers. The manufacturer of your vehicle or machine should be the primary contact for servicing or replacement of the unit when needed.

  3. Where can I purchase a new Delta-Q charger?

    Contact the original equipment manufacturer (OEM) of your vehicle or machine to purchase a new charger. If the OEM is no longer in business, or you need a standard QuiQ Series or IC Series charger, contact one of our network of authorized Delta-Q distributors. These distributors will not have access to models with customized connectors, output displays or software.

  4. There are flashing red lights on the display of my charger. What do they mean?

    User guides are provided on the Support page with detailed explanations of each error code for Delta-Q's standard QuiQ and IC Series chargers. For OEM specific models, please consult the machine's user manual, which will detail fault and error codes.

  5. How do I check or change the charge profile?

    To check the default charge profile, follow these steps:

    IC Series:

    1. Disconnect AC power from the charger or unplug the AC cord from the wall and wait 30 seconds for the charger to completely power down.
    2. As you reconnect AC power press and hold the charger’s button (with the wrench symbol on it) until the red error indicator begins to flash. Once this happens, release the button.
    3. To verify the current charge profile, press the button again and the display will flash the currently selected profile (e.g. P-0-1-1 would indicate profile 11).
    4. To advance through the pre-loaded charging profiles press and release the button until the desired profile is reached.
    5. Once the desired profile is reached press and hold the button for 10 seconds to confirm the profile change and exit the selection mode.



    The process will time out after 15 seconds of inactivity and the charge profile will revert to the profile at the beginning of the process


    For the QuiQ and QuiQ-dci:

    1. Disconnect AC power from the outlet.
    2. Remove the positive lead from the battery pack.
    3. Apply AC power and the charger will display the charge profile number after the power on self-test:
      1. All charge profiles will display as a series of flashes of the ‘80%’ LED light.
      2. Charge profiles #1-6 will also be indicated by the ammeter LEDs (see user guide for more information).
      3. Charge profile number display runs for 11 seconds, then is completed.
    4. Remove the AC Power source and reconnect the positive lead.



    Three flashes of the 80% LED light (***) = Charge profile 3

    Two flashes of the 80% LED light (**) – Pause – one flash (*) = Charge profile 21


    To change the default charge profile, follow these steps:

    1. Enter charge profile display mode, as described above.
    2. While the charge profile number is displayed—for 11 seconds—touch the positive lead to the battery pack’s positive terminal for 3.0 seconds (+/- 0.5 seconds).
    3. Remove the positive lead from the battery pack. The charge profile number will increase incrementally.
    4. To advance the charge profile number again, repeat steps 2 and 3 within 30 seconds.
    5. To lock in the desired charge profile as the default, touch the positive lead to the positive terminal and hold it until the relay clicks. This will take around 10 seconds. The new default algorithm is now stored.
    6. Remove the AC power source and check the default charge profile (as described above).
    7. Contact your original equipment manufacturer (OEM) if your battery pack is not supported by the charge profiles loaded onto your charger.
  6. What is the standard DC output configuration for the chargers?

    The IC650 does not have a standard DC connector and can be adapted to fit most customers’ requirements. This is the standard DC output configuration for the QuiQ battery charger:

    • A 1.8M output cord with four wires, red, black, white and green.
    • Red wire is for the battery positive with 3/8 ring terminal.
    • Black wire is for the battery negative with 3/8 ring terminal.
    • White wire is the temperature sensor; the rubber rectangle coupled with black wire goes to the battery negative.
    • Green wire with male Faston spade connector is the interlock, which carries battery pack voltage and should not be grounded. If the interlock function is not required, please do not connect it.


    For customized OEM model installation instructions please contact the OEM.  

  7. Can I have a list of the pre-loaded charge profiles?

    Delta-Q has charge profiles that support most major battery manufacturers. However, each vehicle or original equipment manufacturer (OEM) has selected battery types and brands best suited to their application. Please contact the OEM for charge profile settings or a list of supported batteries.

  8. Where can I purchase an AC cord for my charger?

    Your local electronics or computer store will carry the AC cords used with a Delta-Q charger. The cord must be at least 16-gauge with an IEC 320 connector, and the recommended maximum length is 6 feet (1.8 metres). If the cord is too long, there will be a voltage drop and may create a fire hazard from overheating.  Use these extension cord wire gauges for the following lengths:

    •  < 25ft (7.5m): 16AWG (1.5mm2)
    •  < 50ft (15m): 14AWG (2.5mm2)
    •  < 100ft (30m): 10AWG (6.0mm2)
  9. Can my charger remain plugged in for a long period of time (e.g. during a vacation)?

    Yes, Delta-Q encourages you to leave your charger plugged in to a wall outlet. Our charger will monitor battery voltage and provide a top-up charge if required. Check the charger periodically and ensure that there is adequate electrolyte in flooded batteries.

  10. How long will it take to charge my batteries?

    Charge time is affected by a number of factors including battery health, depth of discharge, selected charge profile and battery age, so accurately predicting charge time can be challenging. As a guide, a fully discharged pack of new batteries in good health should take 8-10 hours to complete a full charge cycle; but as the batteries age they will take longer to charge and older batteries may take up to 12 hours to fully charge.

  11. Can the charger use 120/240VAC?

    Yes, Delta-Q chargers can handle voltages from 85-265 VAC, and can be used worldwide. Use an IC320 AC cable with a maximum length of 6 feet (1.8 metres) with your charger. 

  12. Can I use lithium batteries with your chargers?

    At this time, Delta-Q is not supporting lithium battery applications for individual end-users. Delta-Q has experience with lithium ion battery charging and can work with original equipment manufacturer (OEM) to provide lithium ion charging solutions in new development projects.

  13. Can I purchase a panel or circuit board from Delta-Q?

    No, we do not sell separate parts for our chargers. Some original equipment manufacturers (OEM) may make output cables or panels available. Safety regulations do not allow us to sell these parts or allow repairs to our chargers. We do not give out our product schematics, as they are proprietary information.

  14. Can the amps be adjusted?

    No, neither the DC output voltage nor the maximum amps are able to be modified. 

  15. Do you sell inverters?

    QuiQ-dci has a built-in converter for 12V accessories. We do not make separate inverters. 

  16. What type of AC phase input does the charger accept?

    Delta-Q chargers accept single phase AC input.

  17. Can I use multiple chargers in sequence?

    Chargers can work in series or parallel depending on the application. Please contact the original equipment manufacturer (OEM) for recommendations.

  18. Does your charger have CAN bus?

    The IC series chargers do come with CAN bus communication capability on COMM’s models but the QuiQ and QuiQ-dci chargers do not have the same capability.
