One point that is easy to overlook it to remember to test the battery at the appropriate temperature, and only test it after a full charge. It's amazing how much battery output depends on temperature.
@@frankmontez6853 Battery output is reduced in cold weather but battery longevity is strangely increased if kept fully charged. Being from Canada I don't know much about hot weather, but wire resistance goes up a little as temp increases.
Making use of the th-cam.com/users/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
@nightpwner Yes you could use a multimeter for checking the charging system but to put a load on the battery to check it's condition you need this tester.
Thanks for great upload and good camera work. This same design has been used by many others, just bought a MotoMaster branded item, same exact features. Your explanation of the charging system test is better than the instruction leaflet, thanks for that also!
Positive first than negative not negative first than positive when installing clamps. reverse order when taking off .same thing for battery clamps .Not good for computers
When connecting to battery, make sure you connect tester to Red/positive terminal of car battery 1st and THEN connect to Black/negative terminal. When removing, perform in reverse. Otherwise, helpful video.
Your battery has 600 cold cranking amps and the meter was dead on. WHAT IF the reading showed 400 for example. How much lower can it be before its time to change the battery?
Alternator failure in most cases is voltage loss ,but in some cases alternator failure can also be good voltage and low to negative amp output varying on rpm..this meter only measures voltage. Most alternators at idle , output 40 to 80 amps th-cam.com/video/AXnl2lvDBMw/w-d-xo.html and th-cam.com/video/IFBPPPpuDiE/w-d-xo.html for a more true meter check. Very little videos as the one i posted above ..I learned this technique from been a car audio Installer. Most auto part stores do not test for amps but only test on voltage causing headaches and wasted time and money ..When they tell you your alternator is good when its not. Especially when its a new alternator and you take it back and they tested via volt meter and not amp! And they insist its a GOOD ALTERNATOR! But like i said most failed alternators are low voltage issues !
Looks and seem like a solid unit, my only gripe from what i can see in the video on the Load Tester is they should put better clamps on it. They look like clamps fro. A china ebay welder and should be nice to have 5 or 6 ft leads. Im guessing the cables are probably copper coated aluminum too. Which would explain the short leads.
I had a trusted mechanic with his multimeter check it when I cranked it. . He said it was 10 v. Borderline he said.. So changed it . I also checked it with this meter. Without cranking, I did the two tests listed on manual. Was alright in the first test failed miserably on the load test . Needle went all the way to ZERO. LIKE TESTING A BRICK.
hey thanks for posting this. i was at a local auto store where i live and saw this exact one but wasn't sure about it. looks like a decent one. cheers.
@nightpwner Rich is absolutely correct. To properly test a battery, you need to test it under a dynamic load, measuring output (amperage), not just voltage. A bad battery will often produce acceptable voltage, but when challenged with a load, it can't produce the amperage needed. The only beef I have over this tester is that it is limited to 100A, which is barely enough to properly test a car battery. Realfixesrealfast demo a more versatile (and more expensive) tester.
@@spelunkerd I did both tests listed on manual . The charge test showed it was good but the load test it failed miserably . Went all the way down to zero . like testing a brick
@@frankmontez6853 That is a surprisingly common situation, in fact it happened to me this week. The other thing that can happen is failure to hold a charge overnight, even if it initially passes a load test. Either case, the battery is pooched. You can try adding distilled water to cells, and you can try a desulfation algorithm with a smart charger, but most often the result is weak, temporary, and unreliable. Better to move on with a new battery.
@@spelunkerd are you familiar with Auto Zone battery tester ? Looks way more modern and expensive. My other slightly used battery was tested by them. Do you think that's a good tester ? Showed 100% charge. ..also checked it with my harbor freight tester and it passed
Not recommended it would be a heavy discharge for this size battery and will reduce its lifetime.... IE it doesn't have the capacity to supply enough current for this size load..100 amps.
So I have a tractor with a car battery 12 volt and when I use tester under load it's around 600 but won't crank tractor over so I charged it for a couple hours and tried again with it set to boost on charger still won't crank so then I hook my truck battery cables up to it and it starts tractor up? So my question is, is it my battery bad or my battery charger bad why can jumper cables to truck start tractor but charger set to boost won't?
There is a procedure to determine starter voltage drop which can give an indication of starting circuit condition. The yellow table on the meter face has two sets of numbers for this purpose. The top row, "Load Volts", is measured during the load test, with the switch engaged. Most people will be looking at the CCA scale or the condition bars during this test, but when and IF the needle stops moving, glance at the voltage graticule at the top of the scales and note the voltage reading. You now need to crank the engine without having it start. I'm a distributor cap, points and condenser guy, so I have no idea how to disable an ECM ignition sytem - and have the engine ever start again! So if YOU know how to do that, crank the engine with the tester still connected to the battery and note the voltage reading while the engine is actually cranking. This reading ("Min. Crank Volts")should be greater than the value shown in the yellow table below the "Load Volts" value you measured earlier. A note in the table says that in the case of an engine greater than 3.6 liters (Canadian here!) or 200 cu. in., use the next higher crank volts value.
+Marc Denham if the regulator is bad ,you could get more than 16 volts in the battery so the acid start to boil and dry it. But you smell the acid, anyway check with a multimeter.
+Gleiver Alzate if I check the battery with a multimeter. What should be normal reading for the battery when the engine is switched off and on? Thanks.
engine runing 14,5 volts, engine off 12,7 or a little higher . if the voltage in the battery drops to 12 or less the battery is bad. check the picture of the tester in this video is a good reference
Gleiver Alzate I checked my battery with a multi-meter and I got: Engine off 12,5V Engine running, head-lights and ac blower on 13,1V Engine running, head-lights and ac blower off 13,1V Is this any good, or is the battery weak? If the battery is weak, it is really confusing me on how my fog light bulbs exploded.

That's the same damn tester they sell at harbor freight for a lot less money. All schumacher did was have a rocker switch instead of a toggle switch. They all come from the same chinese factory!! OMFAO
HF tester people say has aluminum cables, this one has copper. There are some other minor differences. HF is $16 now after coupon, BT-100 is $20 on Amazon after 20% of current coupon. For $4 more I prefer BT-100. In any case, there are $15 ones on eBay from China
This tester is old type bat need underst how to use this simple tester not for ewerione meby not god to use at new car wuth computer for old is perfectly!! once agein tools is simple bat need how to use!!
I'm a technician, that test and very risky, there is a resistance and battery shorting when you press the button, and the battery can explode, there are much better electronic tester, can test many types of battery without risks, of course personal opinion
If it explodes with a 100A nichrome wire load, then it will explode 6 times more with a 600A CCA load. Yes, there are fancy electronic testers that simulate load then print you test results, but they do not cost $20 and - surprise - often are not as reliable.
One point that is easy to overlook it to remember to test the battery at the appropriate temperature, and only test it after a full charge. It's amazing how much battery output depends on temperature.

If the battery is weak, it is really confusing me on how my fog light bulbs exploded.
It says up to 1000 CCA. Was wondering if it would work on a 1010 CCA battery, seeing its not much more than the maximum CCA load?
You would think it would be close.

No, the alternator would make up for any battery weakness and it wouldn't be a good test. You run the engine for the charging system test.
