    Default Benton BX2 Dummies Guide!

    Please somebody tell me the dummies guide to the BX2!

    I have it plugged in on my bike, it is showing charging, the moment you plug it in it shows battery low, then half, the full, how do you set it over to trickle charge? Pressing mode does buggerol, holding mode in does buggerol...

    Dirk if I read the Instructions correctly then it should go over to trickle charge auto. I will be watching this post as I also have it on my Bike. See 3 and 4 below.

    Benton BX2 - 7 step battery charger



    7 STEPS:



    1. Diagnosis & Recovery
    As soon as charging instruction is given to the charger, the unique function automatically checks status of battery (detects voltage). If a deeply discharged battery's voltage is over 4.5V +-0.5V (for 12V battery) or 16V +-0.25V (for 24V battery), charger begins pulse charging with 3A high current and 1.5A low current to recover it, which terminates when voltage reaches to 10.5V +- 0.25V for (12V battery) or 21V +-0.25V (for 24V battery) at the beginning of the process, the charger skips pulse charging and it switches over to pre-selected charging mode.
    2. Bulk
    80% of energy is returned in this phase of charging. Here charger performs in multi-stages:
    For 24V battery
    a) High Rate Charging: Charger delivers constant current of 3.5A until the voltage reaches to 25.6V
    b) Medium Rate Charging: Charger delivers constant current of 3.0A until the voltage reaches to 28.2V at which point the charger switches to Absorption phase

    For 12V battery
    a) High Rate Charging: Charger delivers constant current of 7.0A until the voltage reaches to 12.8V
    b) Medium Rate Charging: Charger delivers constant current of 5.0A until the voltage reaches to 13.9V, at this level constant current is 3.5A until voltage reaches to 14.0V. Finally charger delivers 3.0A current until voltage reaches to 14.1V at which point the charger switches to Absorption phase. Since current is not delivered at highest constant level, BENTON BX2 charger will minimise the heating up of the battery, and hence will eliminate the build up of gases. This ensures more efficient and safer performances.

    3. Absorption
    Use of a constant high current for extended periods of time risks gassing the battery. Therefore a constant low charging current is given at 1.0A to raise voltage from 28.2V to 28.8V (for 24V battery) and 14.1V to 14.4V (for 12V battery). In this phase complete charging up to almost 100% is achieved. Charger switches to trickle charge phase after sensing that the battery is truly fully charged.
    4. Trickle Charge
    Battery is fully charged and ready to use. The battery will signal to the charger and will only take enough current to sustain small loads such as alarms etc or current leaks in the vehicle wiring circuit. Very low current of 200mA is given to the battery. When voltage drops below 25.6V (for 24V battery) or 12.8V (for 12V battery), monitoring circuit senses that battery needs more current to maintain its charge than available in trickle charge phase. The charger switches to Maintenance charge phase.
    5. Maintenance Charge
    As charger continuously monitors the terminal voltage in order to determine if a maintenance charging should be initiated, if the battery is loaded and/or terminal voltage falls below 25.6V (for 24V battery) or 12.8V (for 12V battery), the charger starts maintenance charging pulse at constant 1.0A until voltage reaches to 28.8V (for 24V battery) or 14.4V (for 12V battery). Now maintenance charging is discontinued. Cycle of trickle charging and maintenance charging is repeated indefinitely to keep battery in good condition when it is not in use and enables charger to be left connected indefinitely.
    6. Supply 13.6V
    BENTON BX2 charger provides a constant charge at 13.6V and current up to 5A. This is suitable for maintenance of 12V battery using Float charge approach at 100% of charge. BENTON BX2 battery charger is also used as a power supply with maximum capacity of 13.6V/5A. In this mode spark free function is inactivated. However reverse polarity protection function still works. It has electronic overload protection, which activates if output voltage from the charger falls below 4.5V and current to around 6A (max).
    7. Boost 16V
    To recover severely discharged 12V batteries this mode is useful. High voltage (17V max) at 1.5A is applied to a maximum period of 3 hours. At finish of this stage it would switch to normal charging setting (14.4V).

    Ja ja ok oom!
    But what is the MODE button for if it does buggerol?

    With no battery connected:

    Hold the Mode button in for 3 seconds. The charger should switch over to the 13.8v Power Supply mode.

    With battery connected:

    Hold the Mode button in again, then rapidly depress it once - it should also go to 13.8v mode. Pressing it again (quickly) changes to the other modes.

    If your battery is totally flat, the charger will not operate, then you need to select the 16v 'Boost' mode. As I charge my batteries on a regular basis , they don't go 'flat', so I cannot tell you if the 16v Mode works as above with the battery connected, as the charger does need to "see" the battery in order to work.

    My BX2's mode button works perfectly.
    I connect, I select by pressing mode, I go to the "snow flake," leave and forget.
    Two months later the vehicle gets taken for a drive without hickup.

    Mr Dog,

    I have the BX2 and have successfully resurrected a few 'totally dead' batteries using the Boost function. It works!

    Glad to hear that, diaan! The chargers are fantastic and really do their job well.


    Reliability is excellent, we have had only one failure in over 500 chargers sold.

    Default Benton BX2

    My charger is connected to the setting 13.6v Supply mode, and had engaged the 102amp duel battery, national Luna after 5min of connecting on its own, now there is no sign on the charger how full it is at the moment. Been charging for 4hrs now. Seem not to have switched over to trickle mode yet. Or is it on trickle mode?

    What is the difference between Supply mode and Supply on the charger? Read manual and does not seem to explain. Perhaps I missed something.

    I gather you mean the 'Boost' mode. Battery might be on the way out and not taking a charge? Try disconnecting & reconnecting the charger, see what happens then.

    Does Benton make a dc2dc charger?

    Not yet, but they are investigating the possibilty. I'm also holding thumbs for that!

    Default Benton DC-DC

    Does anyone know whether Benton did indeed started fabrication of DC-DC chargers?

    No idea, but speak to George Bosch about the CTEK one.

    I received email about this just last week and Benton is currently looking at this. Production might still be a while off, however.

    Default Faulty Benton BX1

    Family Dog,
    I purchased a Benton BX1 in 2011 from a 4X4 Megaworld branch and did not use it for 6 months after purchase. When I used it for the first time a red light indicating "error" came on. I returned it to the shop where I had purchased it and they returned it to the supplier. The supplier said the warranty had exprired.
    Any suggestion where I can have it fixed?

    Hi Cobus,

    Unfortunately it is not a serviceable item.

    The Benton BX-1(Pro) model has just been released, I am thinking of selling off our remaining stock of BX-1(M) at some ridiculous price just to clear stock. If you're interested, please shoot me an email at info at repcom dotcodotza (or checkout www.repcom.co.za if you prefer.)

    I have just received my BX2 today, its to keep my Cupra's battery in top form as the car stands sometimes for 3 or 4 weeks, since I installed the sound system the battery doesn't last as long as it did before so I'm hoping I made the right choice as I actually wanted the C-Tek but KWH Agencies, who is one of my distributors, stopped selling C-Tek and convinced me the BX2 is better... hope he is right!
