    Auto XS car battery charger how good is this charger

    How good is this battery charger
    Here are some pictures of it

    What do you know it has non brand name capacitors

    You know I have to recap it

    Re: Auto XS car battery charger how good is this charger

    have had 3 different ones for a good while all similar to that one . not had a problem with any of them apart from a battery it didn't want to charge fully . that one had to go on an old school charger for a night .

        It looks fine for something rated 50W output. I would re-cap it.
        The end-of-charge voltage 15.1V seems a bit high, or 15.5V cold.
        It needs some ventilation slots for cooling but nice heatsinking.

          On the 6 volt battery it stops charging at 7.6 volts
          I do not have a 12 battery that I can charge until I go to work Monday

          I might do that but it not going to be charging batteries for long charging cycles anyway

          Below 10 volts and bring the voltage back to 11.5 for charging controller to charge battery see below—>

          I going to be using this charger at work for our battery operated magnet plate lifter
          Because the charging controller has issues and condyle has to be reset for it to charge the battery right if wait to long to reset it then the charging controller refuse to charge the battery

          The company who made this magnet lifter does not know what is causing the charging to be such a problem with this unit and why it needs to be rest so often

          I even sent one of the controller board back to them and all they did was send a new controller and after a couple of months that one starts doing the same exact thing

          We have three of these units and all three units do exact same thing
          My guess is that it has something to with the way the controller is programmed

              Yes but the question is what and where on this controller

              I think I post some pictures of this controller in next few days

                Re: Auto XS car battery charger how good is this charger

                how much power does the battery operated magnet plate lifter use ? charger should be higher current if used for long times .

                  I have the feeling that some how the controller keeps track how many times the battery is charging and even for how long

                  The reason I think is it very how often I have to rest it sometimes it one a month sometimes twice a month

                  The way this charger controller is suppose to work is that when you plug it in to charge it supposed to go from green to red meaning that it is charging when it turns green it is fully changed

                  However when it does not work right it just goes red and never turns green
                  Until you remove power from the controller to reset it sometimes you have remove the power a few times before it will reset

                  I know this because I have had a meter and a amp probe and have checked how it suppose to work

                  This controller also does the following

                  If you have the magnet on and your battery voltage goes below 11 volts it leave the battery on and will not shut down until the battery voltage goes below 9.0 or so or unit you remove power from it and reset but It will not turn back on until your battery voltage is above 11.0 while it is in this mode it has turned off power to the coil to the magnet but the alarm is sounding the hole time this is done for safety reason

                  I have had to replace the SCR before because the battery indicator shows that the battery is draining very quickly this is how I know when it has failed if the battery load testing shows that the battery is good

                  It has two different types of SCR units in this magnet one is for the magnet coil I am not exactly sure what other one controls but my guess is that it might control the charging current but this is only a guess

                  It has a 110 amp hour battery that is a cross between a car battery and a deep cycle battery
                  It is a very heavy battery

                  The charging current is about 5 amps and is powered by a transformer ( the old school ) to drop the AC voltage from 110 volts to 15 volts AC

                  One note the capacitors on this controller are well know brand names

                      check voltage with your meter . do not trust the voltage shown on the charger . mine all read wrongly .

                        Re: Auto XS car battery charger how good is this charger

                        "Smart" lead-acid battery chargers can get confused.

                        First they look for a reasonable battery voltage >10.5V to be present.
                        If it's lower, say 9V it could mean a shorted cell or super dead battery- not OK give full charging.
                        So some chargers go into lockout and refuse to charge, others will trickle charge until voltage comes up to 10.5V or so and then start high-current bulk charging.

                        I have seen some on-line chargers automatically do an equalize charge after so many charging cycles or say once a month. Your electromagnet charger might get confused doing that and then seeing 9V. Most firmware/hardware guys never expect that to happen.

                          That might be the case because it seems to depend on how much they use the magnet to how often I have to reset

                            About 10 years ago we had a Motormaster smart charger, that would work for a while fine, after 2 or 4 weeks it would be on, but not charging. Which left the vehicle with a dead battery. I can't remember what happened to it afterwards, but: 8 years ago I bought 2 chargers. A CTek and a Battery Tender. Them 2 are on the wall and turned on, maintaining batteries to 99% of its time since I bought them and they never failed once.

                                These magnet lifting devices are out side cover warehouse it is possible that could be part of the problem but do not think it the hole problem
