If we can't see why the battery died or we think it's faulty, we'll carry out a battery test. Our test is very thorough and we'll only ever recommend a new car battery if you really need one. Yes, you can charge an electric car at home. In fact, most EV charging in the UK takes place at home. 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. 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.

Whether it's your first time buying a charger or you're replacing an old one, it’s worth knowing what extra features are worth paying for. Below, we explain what you need to know about battery chargers - including how to get the best from your charger. If you’re shopping in a supermarket, look out for offers on battery chargers; we’ve seen up to one third off a charger with AA and AAA batteries included in major supermarkets. Now low-power functions, such as the immobiliser, won’t have such a frustrating effect when you do come to start the car (after disconnecting first). What’s more, it switches into maintenance mode to protect the battery once it has been fully charged.
Once you’ve worked out what type of battery charger you want, make sure you buy the best rechargeable batteries to put in it. The best AA rechargeable batteries last nearly eight hours on a single charge and won't leak away their charge between uses. However, the worst AAA rechargeable batteries we've tested lose nearly 20% of their charge if you don't use them for 50 days. 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.The most significant thing that marks out one charger against another is its charging speed. Slower, cheaper chargers are usually labelled as overnight chargers, taking somewhere between six and nine hours to charge a set of AA batteries. Fast or rapid chargers work at much higher speeds, taking anywhere from four hours to under an hour to charge your batteries. This requires more technology to manage the voltage and ensure the batteries don’t overcharge or get too hot. As a result, they come with a higher price tag. Our Battery Assist service will help you whether you're a Member or not. And you can also call us out even if it's not an emergency breakdown. Sure, it’s no speed demon, with charging times running from two and a half hours for 650mAh AAAs to nearly six hours for a set of 2,550mAh AAs, but it’s great to be able to fuel up eight AAs in just under five hours. What’s more, the charger works with US and European voltages as well as 240V, so as long as you have a Figure-8 mains cable for wherever you’re going, the BQ-CC63 can travel with you. Throw in safety cut-outs and a five-year warranty, and you’ve got one of the best options out there for charging a whole bunch of batteries at once.
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. Manufacturers often recommend that their batteries are charged best by the same brand's battery chargers. This is because they can adapt how the charger works to suit their batteries. That doesn’t mean you won’t be able to charge batteries from different brands in your charger, though. We tried this out with five battery chargers and found they didn’t have any problems charging generic batteries, but were sometimes slower to charge than with batteries of the same brand as the charger. Charging alkaline batteries The best car battery chargers you can buy in 2023 1. NOCO Genius10 Smart Charger: Best portable car battery charger It’ll need to be attached to a wall near where you park (either on the exterior of your property or in your garage) and connected to the mains.If you don't use the car much, you can leave these connected for long periods without damaging the battery. As the maximum charge a rechargeable battery can achieve decreases over time, many people thought it was useful to choose a charger that shows you how much capacity remains. Make sure to follow your vehicle manufacturer’s instructions for charging your car. These can typically be found in the car handbook Some battery chargers are claimed to be able to recharge disposable alkaline batteries. We recommend you don’t bother with these. We tested two (the Deluxe Battery Wizard for alkaline and zinc-carbon batteries, and another battery charger for disposable alkaline batteries) with Energizer alkaline batteries. After two cycles, on average, we found battery capacity had dropped to just 10% of its original, with huge variations. With such unreliable results, they’re not a gadget worth spending money on.
Make sure all electricals like heaters, windscreen wipers and stereo are off when you park or start the car. Informative interface: We required that every model have some kind of indicator (either a display screen or lights) to signal when the batteries are charging and fully charged. Yes, you can but it will be very slow, potentially taking up to 24 hours to charge your electric car. It’s better to get a purpose-built EV home charger installed.Individual charging: This test was simple. We inserted a single battery into each charger and waited to see whether it began to charge. We wanted to confirm that each charger could charge a single battery at a time, since some (especially older) models can charge batteries only in pairs. Overcharging can occur when a battery is subjected to extreme heat, a poor-quality battery charger or a broken alternator – your engine’s battery charge regulator. When a battery overcharges, the sulfuric acid and water contents of the battery start to boil, causing the plastic casing to swell and then melt. This can have disastrous and possibly dangerous consequences, but ultimately it means you need a new battery. There might be several different batteries available for your car. We'll explain the difference in output and performance to help you choose.
