    Is it advisable to charge them in the AGM/sub-zero mode (14.7v) rather than the normal 14.4v?
    The charger will select the setting it deems best at that point in time. After charging for a while, it will automatically revert to the appropriate setting for the state of charge according to what it deems is necessary. So yep, it might start off in the snowflake setting and then change the rate of charge as it deems necessary depending on the state of charge of the battery.

    Wow, surprised to find it in my PO Box the very next morning. Thanks Eric!

    Something I can't find in the manual; do you know what the charger is telling me when the 'Fully charged' LED flashes off every 2.5 seconds? This happens immediately when I connect a deeply discharged battery. I suspect this is the recovery/pulse mode, but it didn't happen on a second battery I tried with similar voltage.

    Thanks Jim!

    Have a look at the wording on "Diagnosis Mode", it would appear that the battery is hovering around 8v (which is indeed deeply discharged) and the charger is pulsing on & off to try raise the voltage before going into full charge mode. If this takes too long - as I think will be the case - try raising the battery voltage with a normal charger for 5-10 minutes then re-connect the BX-1, it should start charging normally as soon as it has detected the higher voltage of the battery.

    Edit: Thinking about this a bit more, I hesitate to suggest that it would seem that the battery has developed a high-resistance and as such, it is time to replace it.

    I think you're spot on. The multimeter showed a peak pulse of around 16-17 Volts every time the LED flashed. After leaving it for a day and a half the battery voltage was up to 12.06V but very rapidly went down when I disconnected the charger. Battery must certainly have internal damage.
    Very pleased with the results on other batteries. It's that 80% > 100% absorption charge which I've never been able to do safely - very satisfying!

    There have been some changes in the Benton family of chargers, the BX-1(M) model has now been replaced by the BX-1 (Pro) version featuring various electronic enhancements and a more rugged connector system.

    Please refer the opening post on this topic with the changes.

    The following Application Chart might be useful as well, please note we stock everything except the SB-380, BX-3 and BX-6 products.

    Hi FD
    what's the price on the BX-1 Pro?
    my older BX1 drives me nuts, when charging is complete "Full" I cannot change the mode back to any other setting, I'm on my 2nd BX1 and they both do this, different vehicle and bike same problem.
    I'm using a permanent cable attached to all vehicles including bike
    The unit still works but you can't change settings unless it's cold.
    You can PM me the price, I might forget to check here again.

    Thanks

    Hi Eric...yes you have me concerned regarding charging to batteries in parallel...I have a DC-DC charger in my bakkie which charges two Deep cycle batts 130ah in parallel..

    Are you saying this is wrong?

    Do I need a DC-DC for each battery?

    As far as Ive researched the opinions here, if its not the exactly same batteries same age etc. You should use two or charge one after the other.
    But it will be interesting to hear FDs opinion as well.

    Ideally, you should use one charger per battery, although what you are currently doing will work provided both batteries are of identical types and both are new. Over a period of time, the battery characteristics change somewhat according to use and as soon as there is an imbalance between the two, the one battery will constantly try to 'top up' the other one and vice-versa, causing eventual premature failure of both batteries.

    Default Benton BX-1(M), BX-2, BX-4, BX-5 Multi-Stage Automatic Battery Chargers

    I have to say I'm really impressed with my Benton Charger. Unfortunately over the weekend I had it connected to my car while we were at game farm and that night it rained. The charger was very wet and very dead. Opened it when I got home , dried it and sprayed it with can of electrical water repellant spray, closed her up and working perfectly again. It also gave me an opportunity to see how well the electronics inside are made.

    I ordered a BX2 charger from FD this afternoon and just thaught of something. Will the BX2 charge the small 7 Ah alarm batteries? Acording to the specs the smallest it can charge is 12 Ah batteries but know I read previously someware here on the forum that inteligent chargers will probably be able to charge batteries which is slightly out of the spesified range. I know you'll have to watch the little 7 Ah battery so that it doesn't over charge or over heat, but will the BX2 recognise that it's connected and start to charge it in the first place? Have anybody tried this and had success?

    Herman, I'm impressed! The BX-2 is rated at IP65, which is dust & splash-proof, but certainly not waterproof. Was there much moisture inside?

    I agree with your remarks on the electronics, I was also amazed at just how well the charger is designed.

    Simply makes me feel so good that I think I oughta double the price...

    No, not advised. It will charge the battery but I don't know what the BX-2 "Intelligence" will make of this low-amperage battery. Still, there's always a first time, I would also be interested in knowing whether anyone has done this.

    FD I think it will be easy to monitor the 7 Ah battery once it's charging to check what charge it is taking, but will be interesting to see if the BX2 see it and start charging in the first place.

    I have a BX2 bought about 4 years ago if I remember correctly.
    Not done through you though.
    The mode button has given me problems nearly from the start (should have sorted it then but didn't) in that it doesn't move from one function to the other with every click.
    More like every 4th or 5th click.
    Not such a big problem as it was actually only used now and again to charge a battery and the functions a nice to have.

    But, now it's stopped working completely. The power light is on, but connected to a battery it does nothing at all.
    I thought about opening the unit to check for a blown fuse perhaps, but it has some odd screw heads that seems do not want opening.

    Any idea of where I can look for the fault? Fuse perhaps?
    Where can I have it looked at? Serviced?

    Adam, the unit is not normally meant to be serviced, although we have done this because of a Mode switch problem. (The contacts are covered with some anti-corrosion stuff which could prevent correct operation, we used to spray them with a good Contact Cleaner (Kontakt60) but we have since obtained switches so we now replace them).

    We made our own triangular tool to open the charger from a Philips screwdriver as a donor.

    Now it might be a pica-fuse (small little fuse mounted directly on the PCB - can't remember the value) but it could also be a SCR.

    You're welcome to send it to us after January 14th when we reopen and we'll take a look at it.
