Every Home Mechanic Needs One of These...

I'm an engineer and have lots of things around my house with batteries and charging systems on them, cars, trucks, lawn mowers, motorcycles, scooters, tractors, generators, you name it. If it's got a battery and even though you keep a trickle charger on it, sometimes batteries go bad, they just do. Up till now, I've been at the mercy of the local auto parts store to test my battery and/or charging systems. No more, as you can see in one of my pictures, I did a battery and charging system test on my little motorcycle in about 2 minutes. All you need is a little information off the battery to put into the unit and the tester prompts you to do the rest. It was very intuitive and straightforward to use from my perspective. The unit itself, cables and operator manual come in a nicely made case with velcro straps holding the various pieces in position, well done. I have a lot of tools and I was really impressed by the quality of this unit, it looks like something a professional mechanic might use. This wonderful little tool will be added to my repertoire of tools in my shop...I didn't even know something like this existed for the home mechanic, but now I do. I would recommend this unit to anyone who's like me and has a lot of toys with batteries and charging systems...

After a local auto parts store tested this battery and told me it was good. You can see why I bought this unit.

Nice upgrade from typical battery tester.

I've had the $40 battery testers before, but I wanted something with more functionality. When I say this model by CGSULIT, a brand I was familiar with, was available, I ordered it.

This comes in a very nice molded case, similar to the ones the nicer scan tools come in. The case holds the tool, a very nice set of 6'8" cables and the instruction manual.

This works on both 12 and 24 volt systems with batteries from 100-2000 Cold Cranking Amps (CCA.)

To test the battery, you connect the tester's clamps to the battery terminals, go to the main menus and select battery test, then 12v or 24v system, regular or start-stop test, in or out of vehicle, top or side posts, battery type (standard/AGM/Gel,) battery standard (CCA, CA, etc.,) and then enter the range of your battery. Press enter to start the test.

In addition, you can run cranking as well as charging system tests.

The display is easy to read, the menu system easy to navigate.

This is a quality tester for the advanced home mechanic.

pretty impressive battery tester

I've typically just used a volt meter and battery charger.

Then I was having issues with one of my vehicle batteries and decided to try this out.
It comes with a nice case. Seems to be of pretty decent quality plastic and has cables long enough to reach the cab of the vehicle which is where a lot of the testing needs to be done from.

Fit an finish is on par with some higher end scanners I have - pretty nice.

The manual goes through the basics, but it really doesn't explain a lot. But to be fair, other products of the same class don't either. There is some assumption you know what you are doing - if you don't - web searches will be your friend.

I tried it on 2 different vehicles - one with a battery on the edge and another with good batteries and 2 since it is a diesel. I'm somewhat impressed what this tester can figure out.

To use it - hook it up - the battery voltage starts the tester and shows the current voltage.
Go through the test and follow the instructions. It took me more than once to understand the sequence, and figure that I need to be doing this while sitting in the vehicle.

It will ask some questions - knowing the CCA of the battery will be needed to get a more accurate diagnosis. In vehicle, out of vehicle. Temp, just charged or not etc...

Follow the prompts. It does some tests with the engine off, then on, and then under load. It will ask you to rev the engine under load and unloaded to check the charging system. My Truck has been coverted to all LED lighting, so it was having some issues detecting load, so I ended up having to turn on all my aux lighting - so that may skew the data.

When it's all done it - it also has a summary screen to tell you the overall health.

I need to run this a few more times, but i'm pretty impressed with the variations this tester can detect, and I also have to run it to really understand what it's telling me.

So far - I like it - pretty impressive.
Had I known - I would have got one sooner.

No more guess work.... BT705 tester will tell you the good or bad news.

I am a professional technician and had been looking at several of these battery testers. We have one that work supplied for us but it is a joke.
I could test the same battery twice with the unit that the employer supplied and it would give me two different results. The CGSULIT BD715 arrived
early with no shipping damage. The unit is easy to navigate. I have several batteries in my garage. Tested three of them and it correctly identified the bad battery. I had just recharged the battery in my truck. Tested it and the BD715 stated it detected a surface charge and instructed me to turn the headlamps on to drain it. The work unit never did that. Plus it ask if the battery is in the vehicle or not. Several of my fellow technicians have used it and I think we should have several in the shop before long. Great tool for the price. Come in a strong case with slide locks. The flip up kind break.
Very happy with this purchase.

Excellent bit of kit

I had been having electrical problems with my car, all sorts of codes and dash lights poping up, sensors failnig and the like, I had chacked my battery with a digital multi meter and it showed as ok, so I couldn't understand what was going on, A lot of forums talked about how modern cars are very dependant on thebattery as a major part of the electrical and electronic system and how even a few volts of a drop can cause all kinds of problems, So I bit the bullet and bought this. Plugged it in let it do it's thing and it came back to tell me my battery was a dud. Bought a new battery and hey presto all my codes lights and issues were gone. Very easy to use and 100% reliable

Auto shop owner approved!

I own an auto shop and I can certainly say this is a great tool. Love the simple readout of “replace battery” “charge battery” also the cranking test, and alternator output test. is extremely helpful. Takes a few seconds to test vs my $1200 diagnostic tablet which takes several minutes. I got a coupon with mine so I got it for $108 which is a price you can’t beat for something like this. Performs like a $300+ quality battery tester

Great tester.

This tester feels it’s made of good quality.
It works as it should.
It comes in its own hard case with cables and a manual.
We have a vehicle that constantly has battery problems, and the sensor on the dash is on all the time, so we can easily monitor it to determine a possible battery replacement or just recharge it.
I am satisfied with my product.

Darren Dove
Value for money tool

Step by step instructions clear in the display, if the final result could be bolded that would make a great product even easier to see final results of battery state.

Michael Messuri
Battery diagnosis in minutes

I’m have been an ASE certified mechanic for close to 40 years and this product has made battery condition diagnosis easy. This load tester exceeded my expectations and I would highly recommend this product to anyone in the automotive business that deals with battery diagnosis in any capacity.
