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

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

Sorprendente!
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!

Testeur de batterie simple d'usage
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.

Fantastic tool
When trouble shooting the electrical system, a very useful tool to eliminate any uncertainty whether the battery has reached its end of life or not.
