This is a device by conway called kw 510 To je, a battery and battery tool to help you diagnose it to help you charge it and even in some cases, cases fix the battery improve the performance of your car’s battery. So in the box we have the device which looks like this it’s, pretty pretty thick there’s a cooling fan over here and an ac input. We have two battery leads. We have five buttons, two indicators and lcd display. Also in the box, we will find user manual and ac cable, Ok, so let’s find the car and let’s check how this works. I believe that we can check the battery without the ac connection, because the battery will power the tool and right now we have five options over here we can check the battery repair the battery charge. The battery review last results of the battery test and enter the setup over here we can select language let’s stay with english and we can turn off the beep, maybe turn it off adjust the display contrast, maybe let’s bring it here and set charging time. So we can have automatic um charging setting over here. You don’t have to um, keep your timer on and remember to disconnect the charger you can set it to, na primjer, seven hours test the device and check the software version of the of the device, as well as the serial number. Ok, so let’s uh check the battery it’s out of vehicle or in the vehicle it’s in the vehicle, and we want to charge check the battery, not the cranking test or charging test.
Just the battery state test and let’s select that it’s a regular battery and it’s rated with en standard and it’s a 520 amp battery okay and here’s the result, so the state of charge is 93 percent. State of health is 75. We can see what’s. The peak current over here is it’s ‘3 amps what’s, the voltage what’s, the resistance of the battery and and that’s pretty much it now. Let’S try the cranking test, so we need to turn off the engine press enter to test and then i need to go inside the car at and turn the engine on start the engine. So we have the results. We can see that the cranking took about seven seconds and that that includes both the glowplex charging, as well as the voltage going back to nominal state after the engine is on and the maximum voltage was 10 10.2 volts minimum 7.6 and this device rates that that This cranking was normal. Okay let’s perform another test. Ok, so now the charging test now let’s increase revs, and we can see the results over here. We can see that the voltage while the engine is idle, is pretty much the same when the engine is a little bit loaded when the rpm is higher so that’s. Ok, also, we could see the ripple test being performed. This shows us variation in voltage on especially on low revs, and if your an alternator is damaged or is not performing um as it should it can, it can create some communication issues in your car when you have a lot of modules in your car.
Each of those modules is sending and receiving some messages over the can bus and this database is very sensitive to any voltage drops. So if the ripple tests show, you shows you that the voltage spikes are really high. This could this could cause some communications communication issues in your car. Nwo, let me show you how to use it as a battery charger, so over here in the mind menu we are going to battery charge, Koji, which is the third option enter. Naravno, you need to have the uh, you need to have the um ac power cord connected and on the display. You can see um how’s the charging doing right now, so what’s the state of charge, how many amps are going through um to the battery and what’s the current voltage over. Here we have the indicator of the weather condition. So there is a temperature sensor which will limit the limit amps going through the battery if it’s too hot outside. If the ambient temperature is too high and in the winter when it’s lower and it will provide more amps to the battery and there’s also an option for battery repair, so we can select this option over here and enter this mode there’s. A warning that the battery needs to be outside the vehicle, because this will perform some kind of voltage stimulated regeneration of the um of the battery, and this should not be performed. If the battery is connected to the car, it could cause some electrical damage.
So we are sure that the battery is not in car and it’s, repairing right now and over here we have, we have the timer, and now we just have to wait. Ok. So over the past few weeks me and my colleagues were testing it out with a couple batteries, and we have some final thoughts. Kao prvo, it’s cool that it’s an all in one device. You can charge your battery test, your battery and even repair all with a single device, it’s very fast, to operate, it’s easy to operate those five buttons and actually those four buttons are all you need – and this is just a shortcut to the repair function. It works. Uh with uh 12 volt batteries, so if you have 24 volt system, it will not work in your car. It can be powered with 110 volts or 230 volts. Također, the display information is very clear: To je, a cool thing that you can see how many amps are going through the battery and what’s the charging state and current voltage, and usually you have some kind of led indicator which just blinks, if it’s charging and you don’t Know if it’s going to take five more minutes or five more hours and over here, you can actually see what’s what’s internally, going on in the in the battery and what’s the device actually doing right now, and i really like the automatic shutdown feature, so you can Set it to three four five hours and and the device will shut down after this period of time.
You don’t have to wait for it and you don’t have to be on standby to shut it down when you are leaving your workshop and also the ripple test. The alternator diagnostic is a very cool feature in this kind of device, so it will not only check your battery, but also your and diagnose your car. What i don’t like is that when you are using the repair function, you just have the timer which counts uh. How long the how long the reaper is taking, but you don’t know how long it’s going to be so, and i think that if they include some more information on the display, while repairing the battery, it would be very cool. Također, those battery leads could be could be a little bit longer. It would be easier to perform them and test when, where you need to and turn on the engine – and you could do it yourself and right now, with those short leads, you need to have this device uh over here in the engine bay and with longer um Leads you could take it with you to the um to the cabin and perform all those tests yourself without going back and forth between the between the steering wheel and the engine bay, Ok, that’s it more technical specification about this device is in the description below this Video and if you want to buy one of those, you can do it on amazon, also there’s a link to an amazon web page in the description below this video that’s it for today.
Thank you for watching give me thumbs up.
