Some shonky mechanics always have and always will try to swindle money from you. I’ve heard hundreds of people complaining about how a mechanic proved a perfect battery to be dead to a commoner. This way they made him buy one from his store and bought the not really dead one for a dime.
Anything like this can and will be prevented if you bag one of these best car battery testers. if you find that a tough nut to crack, you’ll guide you every step of the way.
Best Car Battery Testers Till Date
Well, these are not anything like smartphone, you’ll automatically know which ones the best. Unlike smartphones, nobody will be telling you that this one good for this and that one bad for that. So, to make your hunt a little bit easier, we’ve sorted out the best car battery testers in the market. These reviews will justify why they’re the best.
1. Schumacher BT-100 Battery Load Tester
Aspects of Interest
Unlike the rest of the digital battery testers down the list, you can always rely on its result 100%. Buth of 12V and 6V batteries can be tested with these. But a load test of 100A can be done on 12V batteries and that for the 6V is 50A.
You can perform all sorts of tests with this on top of the load test like battery condition and starter motor draw. Schumacher BT-100 might look like an ancient relic, but it sure as hell is a lot less mortal than the fancy ones on the market these days. Even o ensure your safety they’ve color-coded and insulated the alligator battery clamps.
The thing about using an analog meter is that you can use it on all species of batteries out there as long as they’re 12V or 6V. You won’t have to worry about them being a gel or regularly flooded or anything. And to make it more ergonomically advantageous.
All but this on the list can measure only up to 1000 CCA. Most other battery testers out there, especially the digital ones can measure up to 2000 CCA starting from 100 CCA.
2. MOTOPOWER MP0514A Digital Car Battery Tester
Aspects of Interest
Having a very straightforward interface, even for the noobs. It analyzes the condition of the battery by testing the voltage, Ampere of the battery and gives a final statement on the present condition of the battery. Thus, unlike most other battery testers you’d find on the market, ones just showing the readings. This one also does the same with the alternator.
You’ll find a bunch of LEDs on the device, these are what tells the conditions of the battery and the alternator. On the left, there are four LEDs indicating the state of charge of the battery. And on the right, you’ll find two pairs of LEDs, one indicating the condition of the alternator, these ones are on the top. And down below is another pair that indicates the condition of the battery.
You’ll find four-digit display here, with this it can act as a voltmeter showing the voltage of the battery. It does so in the range 4-20V DC. Anything below that range will be shown as “LO” and above will be shown as “HI”. Even as a voltmeter, it has quite a commendable accuracy, 0.01V accuracy.
I had to just mention the looks on this guy, black rubber paint really gives a sleek look to it. Manufacturers really did care enough to give the best feeling when you’ll be holding it. And yeah, speaking of the manufacturer’s care, they’re giving a 30 days money back offer and also a very helpful 24/7 customer care.
A bit of irritation on this was the short wires with the leads. If the posts on the batteries are a bit further apart, it might not be possible to test the battery. And another thing is the fakes, there’s a lot of counterfeits of this on the market.
3. FOXWELL BT705 Automotive Battery Load Tester
Aspects of Interest
Unlike the last one, this has a 7.8ft cable, you can even test it from inside your car. Apart from that, there’s plenty to be at awe with this like results based on multiple standards like CCA, EN, CA, MCA, DIN, SAE, JIS, and IEC Standards. Then there’s the Bluetooth which will let you print the results from a Bluetooth printer.
Not only does it shows result in multiple standards but it also can test batteries of multiple types like AGM flat plate, AGM spiral, GEL, and deep cycle batteries and obviously the regular ones. Yeah, it can test batteries of both 24V and 12V. Can you think that a battery tester can change its interface to different languages? Well, this one does.
Despite having a 7.8ft cable, it provides excellent results on its backlit LCD monitor just within 2.5s due to the stable communication and top-notch conductance of the copper conductor within the cable. Cold crank amps, the capability of vehicle staring, healthy state of the battery are all known so quickly.
You can know all these i.e. test all the batteries even if it’s connected to the car.
There’s one little thing about the interface that seems to bug users. If you want to get back to the previous screen. You’ll have to get all the way back to the first.
4. ANCEL BA101 Professional Automotive Load Battery Tester
Aspects of Interest
This palm-sized battery tester with its 3 ft long cable and contrast adjustable backlit LCD monitor is indeed one of the most portable and reliable battery tester and analyzer out there. With it’s insane fast response and near to laboratory precision, it has become a staple in many mechanic shops.
ANCEL BA101 test various parameters of a battery even down to the Ohm resistance of the battery. Unlike that analog battery tester, this one shows results in CCA, JIS, EN, DIN, SAE, CCA, BCI, GB, CA, MCA and IEC Standards. Yes, that’s a long list of standards.
You’ll find this to be quite ergonomic due to having only four buttons and that rubbery texture. the back button allows going to the previous screen, proving to be quite helpful. The 3 ft long cable is also quite thickly insulated even after being all that flexible.
As expected from a battery analyzer, you can test all sorts of things starting from the alternator to the starter’s cranking conditions. Mentionable ones among them are ripple status and charging system status.
Among other noteworthy traits is Bluetooth, you can print the test results out of this by printer with a Bluetooth.
Some folks complained that the unit they received had shown a battery to be 100% good, those batteries were more than a decade old.
5. TT Topdon AB101 Car Battery Tester
Aspects of Interest
Lightweight, rigidly constructed and miniature TT Topdon packs quite the punch. You can use this on basically all sorts of batteries starting from regular flooded, AGM flat plate, AGM spiral to gel batteries. By now you’ve seen that it’s become the norm to have this long list of standards for a tester of this caliber, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB standards, these ones are on the list for AB101.
Having a backlit LED can be helpful but providing one with adjustable contrast is way more than just being helpful. Speaking of being helpful, it’ll show results in just within 3 seconds. If you prefer Russian, Spanish, French, German or even Italian over English, this one will be the optimum choice since it supports all of these.
If you’re testing just the cranking amps or the cranking time, you’ll find those results on the screen within milliseconds. Apart from all those stuff mentioned, this can ensure whether the generator, rectifier diode, and the charging current are alright.
Some units were found faulty, it was suggesting that the batteries be replaced whereas the batteries were known to be fine. The actual problem was that, if the batteries were discharged, then it was suggested to be replaced.
The Route to Best Car Battery Tester
Here in this section of the article, we’ve talked about every single aspect of the car battery tester. This way you’ll get to know what to get and why to get that particular one. You are asking anybody for advice after this.
Multiple Testing Systems/Standards
You’ll get to know about a bunch of rating systems or standards once you’ve started testing your batteries. CCA aka Cold Cranking Amps is mostly used in the states. But from time to time you’ll need to use others like EN, CA, MCA, DIN, SAE, JIS, and IEC Standards.
So, do make sure that the ones you need are on the list specified by the manufacturer. But it’s always better to have a long list.
Types of Batteries
You’ll find batteries come in different species like gel batteries, regular flooded, AGM flat plate, etc. Do make sure that your battery is on the list. And if you’re running a mechanic shop, try to get one with a very long list of batteries in the specs that can be tested.
But always make sure that regular flooding is on the list. I am saying so because you’ll find most batteries are regularly flooded. Most probably yours is regularly flooded too.
Many battery testers give a result upon analysis about the present condition of the battery. Not all testers can be trusted enough to take their evaluation for granted. So, you’ll not understand a bit of what affects what in batteries. If you do know all that then you can easily understand if the tester is giving an accurate analysis.
Another way is to check out the reviews like down below. That way you’ll easily know if those analyses are worthy to be paid heed to.
There’s not much to say about cable length, I can’t even say longers better. Cause, that’ll only bring hassle to a lot. But in many cases, folks prefer longer cables so that they can test the batteries even when they’re inside the car. But that tangling cable can get the better of your anger management.
But do remember to get one with a flexible, otherwise, it’ll really disturb you.
Copper’s best and there’s no other alternative to that when you’re thinking of a conductor for battery tester. One thing to be reminded here is that none of the conductors out there are perfect, none will give the absolute perfect answer. But copper’s proven to give the closest answer to perfect.
You might just get a warranty for a month or two. But with most of the battery testers that might not be the case. But nevertheless, warranty proves how confident the manufacturer is about their product. It’s always preferable to have one with a warranty.
Wider Test Range
It’s a common thing for all sorts of testers like voltmeter, ammeter, thermometers tec. Wider the range that the tester can operate in the better. You’ll find that some battery testers are specified that they have a range of 100-1000 CCA, 100-2000 CCA or something like that.
You see, if you’re working with a tester that ranges to 1000 CCA and what you’re testing is 1500 CCA it’ll show 1000 CCA. In extreme cases, it might just damage your tester.
Accuracy is another very fundamental factor in testers. The best ones on the market at the time is of 0.01 volts. The smaller it is the better. Having an accuracy of 0.01V means that if the tester shows 10V then, in reality, the actual voltage is somewhere between 9.9V to 10.1V.
The virtue of having Bluetooth in these cases is that you can connect these to the Bluetooth printer and print out the results. Why you’ll need it? Well. if you’re working for a mechanic shop or buying it for a mechanic shop, you can keep the results printed out for your client. Trust me, this way they’ll actually believe that their battery is dead.
The digital tester can change its interface to multiple languages. You’ll find it specified on the tester packaging that it can be changed to other languages Russian, Italian, Spanish etc. You’ll find this extremely helpful if you’re a speaker of one of those languages.
Digital ones have screens usually of one of TFT or LCD. LCD’s proven to better, TFT is almost extinct. These screens are usually backlit, not like the ones on your smartphone or TV.
Some have adjustable contrast. You’ll find the ones with adjustable contrast to be of more help than what it sounds like. When you’re working under sunlight or high-intensity light, low contrast will suffice. But if you’re working in a low light condition you’ll be in dire need of high contrast. Leaving it on high contrast will only drain charge.
Testing Batteries of Different Voltages
Heavy-duty batteries are usually of 6V, 12V, 24V. So, it’s usual to get a tester that can work on all of these. But there’s no tester that can work on all three. You’ll usually find that these can work with any one of these or 6V and 12V or 12V and 24V.
My call would be 12V and 24V since car batteries are usually of these two types and mostly 12V.
Frequently Asked Questions
