Bad product. Waste of money and time and effort
Bad. The readings are different on the same battery at different times in fully charged position. Waste of money

Testar startbatterier men även små djupurladdnings batterier t.ex 12AH för handikapp hjälpmedel

Tester di uso intuitivo e ben fatto come di consueto per questo marchio, da me conosciuto per un precedente acquisto. Testato finora su una decina di accumulatori ha fornito risultati coerenti con l’età e lo stato effettivo: non perde un colpo anche riprovando più volte, direi non ha nulla da invidiare a tester professionali (c’è anche la versione che stampa i risultati su carta termica!). Difetti nessuno per ora, forse la confezione in plastica trasparente espone il display a qualche potenziale danno, dato l’imballo di carta un po’ misero. Una chiara raccomandazione d’acquisto, Amazon come sempre puntuale nelle consegne!

Ich habe es bislang mehrfach benutzt bei verschiedenen Autos. Das funktioniert super. Bedienung und Funktionsumfang ist gut. Praktisch ist die led oben. Rot gelb oder grün je nach Zustand. Allerdings sollte die Batterie voll geladen sein natürlich. Ich werde es bei Zeiten mal gegen messen mit einem professionellen aus der Werkstatt. Aber dennoch zu empfehlen

Il n'y a pas besoin de pile (il s'allume lorsque les pinces sont branchées sur leurs cosses respectives). L'interface est uniquement en anglais ou en chinois mais les icônes sont facilement reconnaissables. Ça ne remplace pas un analyseur de batterie professionnel à plusieurs centaines d'euros mais largement plus précis qu'un simple multimètre. Ça permet de tester la tension avec une charge fictive et non uniquement la tension à vide. Il y a également un mode analyse de tension en fonctionnement du démarreur et un mode analyse de tension en fonctionnement de l'alternateur. Sans remplacer des outils dédiés de diagnostic, ça permet de dégrossir quand-même la localisation de panne.

Absolutely amazing. As an auto tech this product worth £60 as I paid . Works really well, as all the products from UNI-T
