User questions & answers

Question:	I am looking for something to test for parasitical draws. Does this test for draws on the battery when the car is not running, when the key is off
Answer:	(1) I have never built a computer using the NZXT S340 Mid-Tower Computer case, although I have built other systems. (2) In reviewing the Amazon purchasers' comments, this seems to be a good case. (3) One quirk of this case seems to be that it is best to mount the hard disk drives before installing the power supply. (4) Hope that this is useful, and good luck with the build. There is nothing that I saw in the Comments that would suggest that the NZXT s340 Elite would be incompatible with this case, but I saw no direct comment on using that combination.
Question:	Will this work on deep cycle batteries used for solar applications? I would guess those are not high cranking amp type batteries
Answer:	YES
Question:	I saw as similar unit at HF, but it has aluminum wires instead of copper, what does this unit have
Answer:	Yes. Come with all the cable you ever need
Question:	Does this test the alternator
Answer:	If you are only able to run a 6+2 by2 or whatever then run that. Any card will run fine and there is no need to stress. HOWEVER more Recently it has been found that very power hungery cards actually like having individual cables for every plug. Its a small gain but there is one to be found do to voltage drop across a power cable. This seems to apply to all psu's so dont turn your nose from the 1200p2 because the will all do this

User questions & answers

Question:	Will this test my alternator
Answer:	No. It will only test a battery
Question:	will this work on 8 volt golf cart batteries
Answer:	Hi Cabo, It might as it has scales for 6 or 12 volt. It would read a little high on the 6 volt scale when checking 8 volt. I can't promise it will work though.
Question:	As this tester puts a 130 Amp load on the battery being tested, is that too much load for testing small batteries such as motorcycle & lawn tractors
Answer:	Hi R.W., this tester will certainly tell you if smaller batteries are in good shape but it is kind of over kill as it works by resistance testing. Kind of like plugging a toaster onto your battery. It will draw a lot of juice off the battery in just one test with smaller batteries so if they are weak you will know it fast and they will likely need a recharge afterward. I use it for 4 and 8 D size batteries for starting large diesel engines. I would suggest a lighter amp load tester for what you are doing. Something around a 50 amp range.Hope this [email protected]
Question:	does this work on a 12 V 8D diesel truck battery
Answer:	This will work on all batteries 12 volts and less A carbon pile tester would be a better choice for the larger 8D battery

Question:	Is the switch momentary or does it stay on
Answer:	The switch is just to test the load on the battery it is spring loaded and stays in the off position .
Question:	Is this made in america
Answer:	i'm sorry to say, this is not made in america. that was the first question i had when i went to replace my old one.ther are only a few that are made in usa and they are more than $300. so they got us over a barrel, you buy this one for under $50 or the next one up is $300. that's what they mean when america does make anything anymore. we do make stuff, but its huge money and priced right out of the market. the us govt needs to step in, tax the crap out of this south east asia stuff so the price would be $150, then the us companies could compete cause they could sell alot more at a lower price. but the us companies dont see those kind of sales numbers, so its hard to compete in a free trade market. so, all in all, the answer is no.
Question:	This is the same unit they sell at harbor freight for 20 bucks right down to the switch, do your self a favor and buy the schumacher instead. tom
Answer:	Everything I purchase at Harbor freight does not last .so I think they sell seconds ..

Product description

The ZTS Mini Multi-Battery Tester (Mini-MBT) provides a comprehensive means of testing more than 15 battery types. The Mini-MBT's microprocessor-based design makes battery testing simple - using a patented, high accuracy pulse load test. After a fully automatic test cycle, percentage of remaining battery capacity is indicated on the LED bar display.

Battery types are clearly labeled next to appropriate contacts. There are no settings, and test results are easy to understand. Its small size makes it ideal for the gadget bag, toolbox, or home utility drawer. Negative test lead/probe conveniently stores in seam at side.

Advantage of Pulse Load Technology:Battery performance is very important in today's electronic devices. The Mini-MBT computes the battery's actual remaining power capacity using a 2-second pulse load test. This pulse load simulates the real power demand that batteries experience in a high drain electronic device. So battery performance is measured, not just voltage. The load is automatically disconnected, so testing will not harm or drain the battery.

TESTING CAPABILITY:

• 1.2v NiMH / NiCd rechargeable [AA, AAA, C, D]
• 1.5v alkaline [AA, AAA, C, D, N]
• 3v cylindrical lithium [CR123, CR2]

Eliminates the need for expensive clamp-on meters and line splitters. Perfect for choosing the correct portable generator to purchase. Easy to use: 1. Plug appliance or light into AmWatt, 2. Plug the AmWatt into any 15A electrical outlet, 3. Turn ON the appliance or light. UL listed.

• Meter gives instant, accurate digital readout
• Readout measures amps or watts used by common-cord connected household appliances (1.0 to 15.0 amps, 125 to 1,875 watts)
• Long 26-inch cord reaches remote electrical outlets
• Rugged, high-impact construction
• Easy slide-switch action insantly converts between amps and watts

User questions & answers

Question:	Can I leave this plugged into an appliance for 2 to 3 days to get an overall reading of what the applicance is using
Answer:	What we got was for 110 volt only... I don't know if they have anything for 220.
Question:	Hello is suitable for honda eu20i output 220v ?. thank you
Answer:	There are a lot of differences of the THP103 and Kill-A-Watt. The THP103 has a cord for hard to reach places, plugs in and gives an instant readout in amps or watts. The Kill-A-Watt is designed to remain plugged into a specific appliance to keep track of how much power is being used over a time period to relate to understanding how one might be charged for power consumption. The THP103 is a quick readout to help plan a generator setup, but with knowing the watts and how often it’s on per day someone calculates the expenses involved over any period of time. Let us know if you find yourself with any additional questions.
Question:	Will this work on 220 volts
Answer:	I bought this just to get the meters to monitor the load. I expect the case itself is only adding $15-20 more. Maybe you can call Reliance and see if they sell parts but I bet they would be more than just buying the unit on Amazon....
Question:	What's the difference in function between this and the Kill-A-Watt
Answer:	NO! - Yeah! The pictures tripped me up also - I ordered the wrong one at first. The MB75 measures up to 3750 watts / per phase (2 meters) which is perfect for me and my 10,000 watt (peak) generator. The MB125 meters are scaled for for a larger generator, don't remember the scale, but it was an overkill for me. I would have thought someone would have corrected the obvious picture error by now? Anyway - the meter is great! It gives me piece of mind that I am not overloading the generator.
