Note: I only used my Ring charger three times between 2011 and 2015 when it failed to work this year. I queried my rights with Trading Standards and they said I had owned it too long to complain despite only using it three times in 4 years! I have not replaced it. **Q: Wat size fuse for inside my ring charger. It keeps blowing the fuse.** A: The max size plug top fuse is 13 amp. If the charger is blowing this size fuse then the unit has a problem and should be repaired or replaced. 10 Amp should be proficient. **Q: Thankyou all so much but manual says to attach black(-) to chassis? instead of both terminals? this is what i'm confused about. help please.** A: Before plugging in machine, attach red wire to red terminal on battery followed by black wire to black terminal on battery then plug in and switch on. Easy to follow instructions on machine casing, works every time for me and charges very quickly. Hope this helps. **Q: How long does this unit hold its own charge before it is used or does it need to be plugged in when in use** A: Plugged in at all times it’s not a starter pack of any kind. Plug in whilst charging like most battery charging units as it consumes a lot of electricity. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A very handy device to have in the garage. *by S***B on 16 August 2016* So after not using one of cars for a week the battery was flat, rather than calling someone out to tell me I needed a new battery I decided to give this a try. It's simple enough to use and even if you loose (throw away) the instruction there is a label on the side of the charger that gives you direction. After about three hours on fast charge the car started first time and has been fine ever since.It's quite handy that it's an all in one charger and that all of the leads can be packed away at the sides, seems to be of a good quality build that will last some years. As a warning do not let this get too hot as the charger does tend to heat up a fair bit on its own.I hope you've found this review useful. If so, please click the "Yes" button below this review. If you have any further questions about the product, or any other comments, please add them below and I'll get back to you as soon as possible. Alternatively, make use of the "Ask a question" function on the listing, you're likely to get several responses from both the supplier and other customers. ### ⭐⭐⭐⭐⭐ Good Standard battery charger *by S***Y on 24 June 2016* Not much to say about a battery charger that does what it says on the tin. What I like is that the mains cable and battery connectors are housed in 'pockets' at both ends of the charger. Neither leads are very long, but are sufficient to do the job intended. The charger has a sturdy handle at the top, which allows for easy carrying.The charger has two switches, one of which can be set to 'slow' or 'fast' charge rate (equivalent to normal or boost charging. The second switch changes the LED display to show either voltage or current.Have only used this a couple of times to charge an older battery on 'fast' charge, which gave it a few days of life in a battery that would only just start the car before charging. also used on a new battery in 'slow' charge, to ensure the battery was up to full charge before replacing the old battery. Am happy that this will do the job, and will last for many years. ### ⭐⭐⭐⭐ Great but use slow charge option *by A***R on 19 July 2020* My Mercedes battery was totally flat after weeks standing idle. I attached the terminals and switched on at the mains. Initially I selected the fast charge option and the charger indicated that the battery was fully charged. Obviously not true as I couldn’t even open the car door without the mechanical key.So I thought it was faulty. But then I turned it off, selected the slow charge option, and then switched it back on. Then it indicated via the ‘charging indicator’ that the battery was charging so I hoped for the best.It took around 2-3 days to charge. But to work out the charge time, take the Ah rating of your battery (95 Ah in my case) and divide by the Amps charging rate shown on the charger which averaged around 2 Amps per hour. Hence an estimate of 47.5 hours to charge which turned out to be about right. Eventually, the battery was fully charged and I’ve had no problems since. Now I charge it up every weekend as the car remains idle most of the time.Easy to use item but would be better if you didn’t have to select slow or fast charge as I almost returned it. Apart from that I’m very happy with my purchase as it did the job and saved me the cost of a new battery. ## Frequently Bought Together - Ring Automotive 8A Automatic Car Battery Charger: Suitable for Vehicles up to 2.5L & Protects Against Over Charging, Black Grey - Ring Battery Video Doorbell (2024 release) | DIY Wireless Video Doorbell Camera I Head-To-Toe View, HD Video | Easy to install (5 min) | With Built-in Battery I 30-day free trial of Ring Home - Ring Outdoor Camera Plug-In (Stick Up Cam) | HD outdoor Security Camera with 1080p video, Two-Way Talk, Wifi, Works with Alexa | alternative to CCTV system | 30-day free trial of Ring Home --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/48392451-ring-8a-automatic-car-battery-charger-suitable-for-vehicles-up](https://www.desertcart.co.uk/products/48392451-ring-8a-automatic-car-battery-charger-suitable-for-vehicles-up) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
