12V Battery Tester

Yes very good easy to use and good for knowing when battery is weak. I use it to know when battery is weak, then use a voltmeter to get accurate reading. The alternator reading is very handy. Excellent for the price.

Had to use it soon after purchase, an excellent tool to have in the boot.

"It does what is says on the tin" For the layman it gives an instant, simple and clear assessment of what you are trying to find out about your battery & alternator. I would have given it 5 but I think the clips are a bit "tinny" & only just about get around your battery terminals. Other than that ~ very pleased.

My husband very pleased with this item, says it's very easy to use and would recommend it.

Easy to use and reassured me that the batteries in both our cars were well charged

Worked very well

Does the job

It works, just do not expect to be buying a premium bit of kit. If your car wont turn over then you likely will already suspect that you need a new battery. This will confirm that, as tested with two flat batteries on two different cars this year. So three stars for confirming that, but, the display is very difficult to see in bright light while the whole device does feel lightweight and flimsy. I doubt that it would survive regular use but then again who is regularly testing their battery? If you can pick this up for cheap then i say go for it but if you want something a bit more premium with a better screen and more information from the device, give it a swerve. As it is, i am happy with the purchase as i didn't have anything else to use but i will be looking for something better for the future and this unit will then live out its days as a spare

Funkar mycket bra Batteri status och laddstatus

Très bonne qualité/prix

Macht was er soll

Je l'ai utilisé quatre fois pour mesurer la tension de batterie. Maintenant plus rien ne s'affiche, ni LED, ni Affichage numérique. Lorsque je le connecte en polarité inverse, la LED correspondante s'allume, j'en déduit donc que c'est un problème du circuit électronique. Très cher payé pour faire 4 mesures....

Zeigt zuverläßlich und punkt genau an wie voll die Autobatterie ist..Bei jeder Prüfung leuchtet im linken Diagramm je nach Ladekapazität eine grüne ,gelbe oder Rote Diode an Zusätzlich wird noch genau die exakte Spannungsstärke in großen roten Zahlen ermittelt und angezeigt. Der Batterietester ist ein praktisch guter Begleiter und paßt im jeden Handschuhfach.Es werden keine Batterien für den Tester benötigt ,da es sich die Energie von der zu prüfenden Autobatterie holt. Top Preißleistungsverhältnis .Es ist umso wertvoller,da so ein Gerät in einen normalen Geschäft heutzutage kaum zu bekommen ist.
