Silverline Battery & Charging System Tester 6V & 12V (282625)

It's bigger than I expected and made of solid Chinesium metal. It absolutely does the job and doubles as a toaster too as you can see from my photos. I've spent this week recovering a completely dead mobility scooter battery. The two 12v units were so dead that they would not even accept current at 30v. Just a tiny trickle of 30mA but that kept climbing. After some hours the 12v batterys were giving out 6v. I kept going. I also connected an Amazon desulficator. Thankfully they both deliver over 12v and although drop to 8v on test they are making it glow nice and bright. The scooter itself is still in a bit of a mood having not had power for 5 years, it's flashing the spanner at me. To test a 12v battery properly you've got to put a decent load on it and check the voltage whilst doing that. This wonder of Chinese technology does exactly that and you don't even need a Bluetooth app (joke, it's just a resistor, a gauge and some jump leads).

OK so it does look a little cheap - but it is 1/2 half of very similar products on this site - and you can always connect your expensive voltmeter in parallel for a better reading. You are basically paying for the load resistor (in the heatsink you see) to load the car battery. It is very useful to take with you if you need to replace a failed battery under warranty and they try to "wiggle out" by testing it in such a way (i.e. not loaded) to say it is working perfectly! I would take the voltmeter too just in case. In my case - this device helped replace a battery so it is worth it (cheaper then a battery); it would not be worth paying 2x for a better one as that would be almost the price of a new battery thus why bother - might as well buy the new battery and be done with it.

This product is ideal for me, it is an old school method of testing battery performance and replicates a test we used to do when i worked in a garage 30 years ago. Basically its a 100amp resister with a built in volt meter. The resister is operated on by the switch for a maximum of 10 seconds, whilst monitoring the battery performance from the volt meter allowing you to determine if the battery is ok or not. My son in law has also used this device you check his battery, works great. It will certainly tell you if your battery is in need of replacement. You must ensure the battery is fully charged before the test.

Very rugged and simple tool that does the job it is designed for perfectly: Shows the voltage of the battery, static and under load (the switch brings a resistance circuit into play that simulates running the starter motor) showing an acceptable range for a given load. I was able to determine that my solar panel was overcharging the battery, and that I needed a solar controller to protect it. Indispensable kit for troubleshooting battery problems!

I bought this jump charger because we have a second car which seems to use more than average current when not being used, and as I often don't use the car for 2 - 3 week at a time, the battery is often flat. With the Silverline jump charger It starts every time. I just leave it plugged into the mains and it's always there ready. Brilliant! It'll also trickle charge the battery or blow your tyres up, but I haven't tried that yet. All this for a few quid. In my opinion, it's amazing value.

Easy to use. Good read out. bit tinny but for the price a good bit of kit. does exactly what you want it to.

Did exactly as it said. Great for testing a battery

Cheap and nasty, typical Chinese build quality. However, to be fair it's an amazing price and it works well enough to determine if the battery or charging system has a problem. Only really suited if you need to check your batteries a couple of times a year. Not suitable for every day use - so no good as a tradesman too.

Très bon produit j'adore le concept.. rien de mieux pour avoir une idée de l état de la batterie 🔋 très satisfait merci

El producto se nota que es de calidad nada más abri la caja, es robusto y cumple con sus funcion.! Ojo hay que saber como funciona un comprobador de baterías de este tipo de carácteristicas. No hace falta ser ingeniero en cualquier página web hay tutoriales que te explican como emplear el aparato !!

Tester provato ottimo per l’utilizzo da privato

Actually works fine for the money. Late review but good

Sehr gut Produkt, sehr gut Verkaufer!
