It has a 6a output, which gives it a decent amount of punch when it comes to topping up low batteries in a pinch. My bike wouldn't start after a month of autumn inactivity, but a 30-minute top-up from the Ring charger had it firing on the button again. Lesson learned - just leave it plugged in. 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. Express delivery option to offshore, highlands and remote postcodes may take longer than the usual one working day. The surcharge may not apply to small items being sent via Royal mail or MyHermes etc... Where possible we will try our best to avoid courier service for surcharge areas. There are several chargers from CTEK in this list, and this CS ONE option is the top dog of the range. It's a smart charger that can repair, maintain, charge and detect bad cells, as well as a host of other features.
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. 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 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. This smart charger from Ring does basically all batteries except lithium and features a seven-stage charging process that's supposed to be kinder on your battery. 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.
What is it?
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 With 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. 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 best car battery chargers you can buy in 2023 1. NOCO Genius10 Smart Charger: Best portable car battery charger 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. These put some load on the battery so that it isn’t simply under constant charge, as this can also, paradoxically, damage the battery and reduce its capacity as well.
What’s it like?
There’s a 12-month warranty on parts and labour, though Draper is a brand associated with rigorous professional workshop quality, so you’re unlikely to experience issues with this battery charger. Its portability also makes it great for flat dwellers and other motorists without mains access near to where they park. 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.
Available with either a UK three-pin plug (part number RSC804) or EU two-pin plug (part number RESC804) 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. 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. You can’t damage the charger either as there’s short circuit and reverse polarity detection, just in case.The solution, of course, is to leave your bike with its battery on charge when it’s not being used. This is particularly true for bikes that are laid up for winter, and in this case, a battery optimiser/maintainer can be useful, as it not only charges the battery but it carries out a series of conditioning cycles. 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.
