You also have to consider what kind of battery you have: lead-acid, AGM (an advanced version of lead-acid) or lithium-ion. Some batteries are versatile enough to support multiple technologies, others not so much. You often find versatility has a direct correlation with price.
It’s compatible with lead, gel, calcium, AGM and EFB-type batteries, or, in other words, pretty much all batteries that we use in the UK car market. It has overcharge protection so you don’t have to worry about overfilling and ruining your battery, something which is a major disadvantage of regular chargers. There’s also a winter mode to protect batteries during colder temperatures, as well as being ‘smart‘ to not damage batteries that are fitted to Start/Stop vehicles.
Car batteries are not power banks, so they don’t store electricity. Without going into the science of it all, they generate the energy needed through lead-acid chemical reactions. When a car is started, a very high current is sent in a very short burst to the crankshaft to get it moving. The alternator then does all the work on the electricity front. Available with either a UK three-pin plug (part number RSC804) or EU two-pin plug (part number RESC804) Instead of just putting a fixed rate of charge into the battery, the Ring RSC806 uses a seven stage process to look after your battery. It’s important to note that car battery chargers are not jump starters. A jump starter will offer the engine the short burst needed to get it going, but from that point on, it’s the alternator that recharges the battery. This is why, if you’re ever jumpstarting your car, you’re asked to run it for a good while to replace enough of the battery, so that you don’t require a jump start when you come to drive again immediately afterwards. Which car battery charger is best?
The materials used in a battery are susceptible to degradation, and user behaviour (among other factors such as weather and age) can affect the life of the battery’s materials. The O-ring connectors are a little useless for most modern cars, as they’re either too small, or you have nowhere easy to connect the negative too as there’s only a positive terminal. But the crocodile clips are well made and feel of high quality. With that said, read on for our buying guide on how to buy the right car battery charger for you, alongside our roundup of some of the best options available. However, they require very different charging characteristics, and as such, you should be careful not to pair the wrong charger with the battery, as this can have a negative effect on the battery and can even be dangerous. The RSC806 is literally a plug-and-play sort of deal. All you have to do is connect it and the charger will regulate itself and adjust automatically to a long-term maintenance mode once the battery is full. STOP/START SupportedWith a comprehensive array of modes, terrific build quality and intuitive functionality, the Genius10 is a bit of a, er, genius. If the price is a little bit beyond your budget, or you have a smaller vehicle, there are other NOCO Geniuses (Genii?) with lower amperage that will deliver enough for your needs. Ok, that's a bit flippant because, in addition to those scant requirements, I also want it to be wall mounted, with a hard connection to my battery, so I don't have to faff about with crocodile clips. Tested by Richard Newland for five months across six vehicles. Quality 5/5, Value 3/5. Dead batteries are like flat tyres – utterly infuriating and one of the least glamourous replacement parts in biking. But critical to your riding pleasure. While you can't prevent punctures, you can prevent dead cells with a motorcycle battery charger and conditioner. If you’re only needing a one-off charge, then easy-snap-on crocodile clips might be better. If you’re a flat dweller or your off-street parking doesn’t have convenient access to mains power, you might need to consider a portable or solar power charger. And this one from CTEK is superbly clever. Not only does it do everything you'd expect: charging, recovering, conditioning and maintaining whatever vehicle battery you connect it to (and yes, it does them all, from Lead Acid to Lithium-ion in all wet, AGM, Gel and other forms) – it does it without any programming from you.
The best car battery chargers you can buy in 2023 1. NOCO Genius10 Smart Charger: Best portable car battery charger But buying a car battery charger isn’t the most straightforward task. First, there are different types of car battery chargers to choose from. There’s also a choice of connectors, depending on whether you’re regularly maintaining your car battery or just recharging as a one-off. Key specs – Size : 16.8 x 6.5 x 3,8cm (LWH); Weight: 0.6kg; Voltage : 12V; Max current: 5A; IP rating: IP65; Crocodile clips: Yes; Eyelet connectors: Yes; Mains or portable: Mains; Battery compliant: Lead-acid/gel/Lithium+; Stop/start compliant: Yes; Maintaining: Yes; Jumpstarting: No; Operating temp: 10-40°C From traditional car battery chargers to portable and solar-powered ones, there are options available to suit a range of budgets. However, buying the cheapest doesn’t always mean bagging a bargain. If you’re caught with a flat battery, the very last thing you want to find out is that the tool you’ve invested in to remedy the matter is a dud.Charge the unit, and then take it on tour. Once charged, it'll hold its power for a year and will recover a dead bike battery enough to start your engine in around 15 minutes. The charge is delivered to your battery progressively, too – reducing the risk of jump-start damage. It's absolutely superb and really works. Yes, it's a pricey solution, but it works brilliantly and is invaluable if you're off the grid where your bike lives. FREE UK delivery applies to Zone A, UK Mainland England, Wales and Southern Scotland (Central Belt of Scotland) and Excludes surcharge post codes and areas. Once full, the charger adjusts automatically to 'long-term maintenance mode' and keeps the battery conditioned and topped up, ready to go next time the sun's out. It has reverse polarity and short-circuit protection to assist non-experts like me, and is even IP65 rated for all-weather use, which is reassuring if your garage or shed gets damp. The whole unit is also IP65 rated, which means total protection from dust and low-pressure water from any direction. Safe to say you could leave the unit outside on the wall of your garage without worry.
