    We have been using this in our Parts Department of Heavy Truck Dealership. Saves disturbing service techs to test batteries. We did side by side testing with our very expensive tester which we need for warranty claims and the results were almost identical. Very handy unit. We use it to load test batteries, but it also test starting and charging system.

    This battery tester is great for home use. Inexpensive and works well.
    The only issue I have is on the display screen. Information at the top of the screen is spelled "Imformation". I had to look at my screen a few times to make sure my eyes weren't playing tricks on me.
    The quality control slipped on that one.
    Other than that the tester works great.

    Great lead acid automotive 12 volt battery tester. Unit does multiple tests including CCA, battery resistance, charging circuit function and more. It's worth every penny. Lightweight and accurate (read a review of multiple similar units comparing cost and functions). It was just as accurate as units costing 5 times as much.

    This is a fantastic tester, easy to use, with clear instructions, well-made. I had a battery that I felt it was going after I let my headlights on for a couple of days. Had to jumpstart the car and drove for about 30 minutes to give it a chance to recharge. In the meanwhile, I received the car battery tester showed that I only had 2% power and the battery had to be replaced. Proceeded to charge the battery with the charger for 12 hours and retested the battery again. The result was that I had only achieved 52% of the charge and the cranking power was down from 430 CCA to 300 CCA, normal. I decided to have the battery replaced sin it was eight years old and do a lot of short driving. I am keeping this tester handy so that I can monitor the battery every three months and if because of my short driving needs to be toped off, I will be using the charger. This MP0515A 12V Car Battery Tester is a MUST-HAVE in every household that has a car. I highly recommend that you get one. The only thing that you have to know before testing the battery is what the CCA (Cold Cranking Amps) does the battery have, which must be indicated on the battery, that is the only information that has to be entered, the rest is a choice.

    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!

    Efter snabb kontroll av det egna batteriets kondition, är det lätt att förstå varför de positiva recentionerna från den övervägande andelen nöjda kunder uppkommit. Istället för att upprepa det redan sagda, ser jag anledning att påpeka värdet av att, genom den breda analysen, kunna bedöma det meningsfulla i att renovera ett batteri som börjat tveka i starten vid lägre temperaturer.
    Specialister i batteribranschen ser möjligheten att renovera ett bilbatteri som främst uppvisar:
    - mer än halva CCA jämfört med fabriksnytt batteri
    - mer än 70 % förmåga att ta laddning
    - mindre än 30 mᾨ inre motstånd
    - mer än 10 V i det övre horisontella fältet efter den branta kurvan under startprocessen
    Vad gäller manualens beskrivning av printfunktionen, måste medges att den i det fallet inte i någon högre grad uppfyller kraven på begriplighet. För den ovane datoranvändaren kan ett tips vara följande, efter att Motopowermätaren anslutits till datorn och dess printfunktion aktiverats:
    1. Klicka på datorns PAINT-mapp
    2. Klicka Ctrl och bokstaven o
    Då kommer alla bilderna upp på datorn (vanligen intressanta är fyra resultatbilder: Battery, Start, Charge, Wave). Därifrån kan de lätt kopieras (blåmarkerad bild genom Ctrl c ) och överföras till ett Worddokument (genom tangentintryckning Ctrl v). För att fritt kunna flytta bilderna på A4-dokumentet måste varje bild dessutom formatera genom att:
    1, Vänsterklicka dubbelt på bilden
    2. Klicka "LAYOUT" på uppkommen meny
    3 Klicka "Framför text"
    4. Klicka OK
    Med vänster mustangent kan man därefter förflytta bilderna på A4-dokumentet som man vill. Värdefull utskrift inför kommande renoveringsförsök. Trots oklarheten runt printfunktionen, överväger mätarens föredömliga konstruktion i bedömningen, varför toppbetyget kvarstår.
