MOTOPOWER MP0515A 12V Car Battery Tester Automotive 100-2000 CCA Battery Load Tester Auto Cranking and Charging System Tester

This is my pride and joy as a diesel technician — it works excellently. The compact and light design makes it feel like you’re holding a smartphone. It’s easy to use, great value for the money, and very versatile. The cable length on this bad boy is excellent.

Nice! Works great. The color screen is clear and I like how it can display charging system voltage during cranking/engine start. I like how it can also provides ripple voltage to test the charging system. I know this item didn't receive the highest reviews on a YouTube site compared to some other brands but it seems to do the job just fine for the price (I got it on a sale).

I work in an oil change shop and we test the battery for every car that comes in. The shop is equipped with a tester branded by a very popular battery brand, but their tester is a piece of junk. It’s enormous, like the size of 2 foot long hoagies next to each other, it constantly needs the clamps adjusted, it has an onboard battery that when dead renders the tester inoperable, and it gives false readings time and time again. So I decided to cut out the middleman and get a tester of my own. This little thing is excellent! It does so much more than the shop tester, it’s more accurate, it’s faster, it’s easier, it’s smaller, it doesn’t have to be charged, and it gives more information when a battery is bad which makes it easier to convince customers that they definitely need a new battery (note that I never push things to customers that I don’t stand behind and I genuinely care about safety and longevity of people’s 2nd largest investment). If you test 50+ batteries a day, pick this thing up immediately. If you need to test the odd go kart or ATV battery here and there, pick this thing up immediately. If you think your alternator is going bad and you don’t want to pay $160+ to find out, pick this thing up immediately.

This little battery analyzer works like a champ. It gives you the actual voltage, the actual resistance of the battery and the state of life. I've been using mind for about 2 years and it does what it supposed to do.

great deal works well

I needed a battery tester that did more than just give me a "GOOD" or "BAD" reading. I need to know how good or how bad the battery is and this battery tester gives me all the info I was looking for - - it gives me measurements for Actual CCA (so I can compare that value to what the battery is rated for CCA), Actual Voltage, State of Charge (in percentage, not just a High/Medium/Low rating), and State of Health (also in percentage instead of generic High/Medium/Low rating). It also give another battery measurement I didn't need, Resistance in mΩ, measured down to one-one hundredth (2 digits right of the decimal). And that just covers the Battery Test features - - this multi-meter also does a Cranking Test when starting the engine, a Charging Test to check the alternator output, and a Ripple/Wave View showing a quick graphic of the output of the battery or alternator or power station you are testing. It even has a print feature to print the screen capture pictures you take. The User Manual gives clear instructions, making it easy to start using this tool just moments after opening the package. I'm impressed.

Made a good choice. Instrument is sturdy, handy, intuitive operation, consistent data return. I've given up big time mechanics but like to still be able to troubleshoot and repair basics. This was a perfect add to the toolbox. My 25yo sports car and my 45yo Harley benefit as much as my new truck. Cables are good for all. Battery and electrical status are easily taken, read, and shared.

Did everything I needed done in relation to determining if my battery was functioning properly and still had useful life. All at a reasonable cost. Recommended product.

Conformes à mes attentes

The MOTOPOWER MP0515A Battery Tester is an incredibly handy tool that takes the guesswork out of battery and charging system health. As someone who hates getting stranded with a dead battery, this tester has been a game-changer! Why I Love It: ✅ Super Accurate – Gives clear readings on battery voltage, CCA (Cold Cranking Amps), and alternator performance. Matched my mechanic’s diagnosis perfectly! ✅ Super Easy to Use – Just connect the clamps, press a button, and get instant results. No confusing menus—great for beginners! ✅ Saves Money – Helps avoid unnecessary battery replacements by confirming whether it’s truly dead or just needs a recharge. Also checks if your alternator is failing! ✅ Compact & Durable – Fits in my glovebox, and the build quality feels solid. I’ve tested it on multiple cars (including my old truck and my wife’s SUV), and it’s been spot-on every time. For the price, this is a no-brainer for DIYers or anyone who wants to avoid surprise breakdowns. Highly recommend!

Works great, very user friendly and fast to give you a report.

Eccellente, preciso e facile da usare

Araç akümü test etmek için satın aldım ve test sonuçlarını aldıkdan sonra akücüye gittim ve orada kocaman eski usul makineler ile tekar ölçtürdüm, sonuçlar birebir aynı çıktı. akü sağlığını, gücünü kalan ömrünü şarj deşarj durumlarını ölçebiliyor üstelik avuç içi kadar küçük yer kaplamıyor.
