RING 12A Smart Car Battery Charger for Vehicles Up to 5.0L: Compatible for All Battery Types

This is one fine battery charger. It has brought two old batteries which I thought were ready to be thrown away back to life, which has saved me over £300 in my solar power DIY project. The unit is fairly compact and very light. The functions are extremely useful, especially the CCA and battery life tester modes. The backlit display is very easy to read and although there are many functions on the device, after 5 minutes of pressing buttons, it was very simple to operate. The instructions manual does the job okay but it could be a little better at explaining how to access some of the functions. The trickle charge and smart charge functions are great at charging and keeping the battery topped up without having to worry about over charging. It charged an 80Ah 720A battery from my old Porsche 911 with almost no charge to 100% charge over night. The battery was so badly discharged that it would not register on a couple of cheaper chargers that I tried before. Overall, a very good investment and despite it's more expensive cost, I definitely recommend it. One word of warning though, the unit has a fan that kicks in when pushing AMPs into the battery. It might irritate some partners if you leave the unit to charge a battery in your kitchen over night! ;-)

This is a very useful piece of kit. I leave my battery on trickle charge in the garage when car not in use. It charges to 100% and then cuts out so Ieave it on charge when we go away and using my wife’s car. I only do less than 3000 miles a year in my car so need a reliable charger. This is my second charger. Make sure you keep the receipt and register the charger with the manufacturer. It’s guaranteed for 5 years.

I have not had a battery charger for years however my sons two year old battery discharged because his car had stood unused for several weeks so I thought I would help by purchasing one,I picked this charger as it had a good product name and it was a smart charger I use my car only now and again so there is a risk my battery may discharge and as this charger is designed for stop start batteries it was a go for me,I am an engineer by profession so know a bit about engines and batteries so I went for the 12amp version as to kick start a discharged battery the ampere output is important,I put discharged battery on smart charge and left it for 24 hours with the result of only 60% so I used the full output of 12 amps and left it again for 24 hours this time the charger achieved a full charge,this charger has the added ability of a clear LCD display so you can test battery in many ways as well as a alternator test its a very high spec unit all round,I is not the cheapest however my experience with this unit is very good and I recommend it highly.

Great bit of kit, Does a proper job at recovering a flat battery. Two things I noted in using it. 1. All the fancy settings are probably never going to be used by a normal home user. All the option are a little "one-time wonder". The main button which is charge it as fast as you comfortable can until its full again, is probably all that will really be used by most. I looked at the more confusing Amperage options and after some googling about, found that anything above 2amps will potentially shorten the life of the battery with the highest liable to buckle the internal cell plates! So again, probably just the charge it until full option and maybe the trickle charge over winter one for people like myself with Motorbikes that might stay off the road over winter. 2. While it is running (and this is more for the over winter trickle charge type option) the screen stays lit all the time. There might be a way to switch it off, but I noticed it on a few times when I checked back over a number of days and it makes me feel like it would be consuming unnecessary power by doing this. I would like to see it drop the back light after 10 minutes or so. Otherwise a good piece of kit albeit with a strangely placed rear hook that means it hangs at 90 degrees. go figure.

Polecam. I nie byłem przekanayn tym zakupem ale uchronilem się przed zakupem nowej akumulatora z baterii start i stop. Funkcja auto charge super dla osób nie mających bladego pojęcia (np :żona) 😋

Mi è stato consigliato da un amico, il prodotto è pieno di funzioni facili da capire. Efficiente e funzionale, leggero e compatto, a volte un pò rumoroso.

L'utilizzo per la ricarica delle batterie del "trattorino rasaerba", che essendo molto "vecchie" e con le bassissime temperature di questi giorni spesso non funzionano non permettendo l'utilizzo del trattorino (trasporto legna per caminetto) pensavo di doverle ricomprare ma da quando ho acquistato il carica batteria RSC612, mi limito a far caricare "in automatico" le batterie. La ricarica fa diversi livelli di ricarica con amperaggi e voltaggi diversi, arrivando in una 15ina di ore al 100% del potenziale delle batterie (mai capitato in precedenza con altri accumulatori) le fasi di ricarica vengono visualizzate sul comodo display quando si raggiunge il 100% il sistema va in carica assistita di mantenimento a bassissimo consumo, ci sono molti settaggi che per adesso non ho mai gestito, ovviamente si possono ricaricare molti tipi di batterie (auto,moto, camper, trattori pesanti) pur dichiarando che per adesso non le ho utilizzate, sono molto soddisfatto della qualità del prodotto, consigliato !

Fatto bene con scocca antifurto ed 1 sacco di funzioni ,
