- Reviewed in Canada on April 5, 2025Verified PurchaseThe 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!
- Reviewed in Canada on June 19, 2025Verified PurchaseGreat 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.
- Reviewed in Canada on January 11, 2025Verified PurchaseThe media could not be loaded.
- Reviewed in Canada on July 7, 2025Verified PurchaseWhat a handy tool. I have owned many battery testers and keep my carbon pile handy but this is so easy to carry and works well.
- Reviewed in Canada on February 7, 2025Verified PurchaseThis 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.

- Reviewed in Canada on June 27, 2025Verified PurchaseWorks excellent. Never had a concern with the product. I would recommend this product.
- Reviewed in Canada on June 23, 2025Verified PurchaseWe 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.

5.0 out of 5 stars Gute Tester zum fairen Preis
Verified PurchaseHab einige Zeit gesucht um das richtige Gerät für mich zu finden. Preis Leistung stimmt bei dem Tester. Einfach in der Bedienung und Selbsterklärend.
Das einzige Manko, wenn man den Tester auf Deutsch einstellt ist die Übersetzung grausam. Also eher für Leute die der Englischen Sprache ein wenig mächtig sind.
- john lovetinskyReviewed in the United States on February 22, 2025
5.0 out of 5 stars Good tester
Verified PurchaseThus is a pretty good tester for the money. It's pretty straightforward and seems pretty accurate. My car started cranking slow in the cold weather, my battery tested poor. I replaced the battery, trickle charged the old one, and tested it again and it still tested poor. Good enough tester for me.

5.0 out of 5 stars Väsentlig info logiskt presenterad
Verified PurchaseEfter 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.

5.0 out of 5 stars Tester per batterie MP0515A ottimo prodotto
Verified PurchaseHo aspettato a scrivere la recensione di questo prodotto che abbiamo comprato quasi un anno fa e lo abbiamo utilizzato più volte. E' un ottimo prodotto.
Ha veramente molte funzioni di cui le principali sono quella di verificare lo stato di salute della batteria e verificare se l'alternatore carica correttamente la batteria. Può anche fornire un grafico dell'andamento della tensione della batteria rispetto al tempo.
Si accende collegandolo alla batteria che si vuole testare. Importante: prima di provare una batteria questa va caricata completamente.
Consente di testare 5 tipi di batterie al Piombo:
1) Classiche acido liquido delle autovetture.
2) AGM Tablet: sono quelle a forma di box usate spesso per l'alimentazione dei servizi del camper o nei piccoli impianti solari
3) AG Winding: sono quelle che hanno una forma composta da vari cilindri tra loro accoppiati.
4) GEL
5) EFB sono quelle ad acido liquido, più costose perché hanno un particolare trattamento delle piastre, a volte installate sui mezzi dotati di start/stop. La sigla EFB viene riportata sull'etichetta della batteria.
Scelto il tipo di batteria che si vuole testare va quindi impostata la capacità di spunto a freddo (CCA) tipicamente la corrente max che la batteria può fornire quando deve far partire il motore a freddo. Anche questo dato è riportato in Ampere (A) sull'etichetta della batteria e non va confuso con la capacità della batteria che è invece riportata in Ah.
Ha correttamente rilevato che la salute della batteria originale della nostra macchina dopo 11 anni di onorato servizio era scesa al 30% dell'efficienza e infatti sotto 0° a volte non ce la faceva. Stesso discorso per la batteria di uno scooter che era scesa al 20% dell'efficienza.
L'abbiamo provata sulla batteria AGM dei servizi del camper con capacità di 100Ah e CCA 800A. Batteria con tre anni di vita e trattata bene con cicli regolari di ricarica e desolforazione. Il test ce la da ancora al 100% di salute.
Provata anche su una batteria (che ha un anno di vita e perfettamente funzionante) ad acido liquido della vettura, da da 95Ah e CCA 830A, anche su questa ci ha dato uno stato di salute del 100%.
Peccato che il manuale sia solo in inglese.
Comunque è un prodotto da 5 stelle. Perché penso che chi si mette a fare dei test sulla batteria e sull'alternatore sa cosa sta facendo e il manuale è dotato di molte immagini che aiutano a capire.
