10Amp Car Battery Charger, 12V/24V Car Battery Charger,7-Stage Charging Automotive Smart LCD Screen Battery Charger Maintainer/Pulse Repair Charger Pack for Car, Motorcycle, Lead Acid Batteries & AGM

TLDR: This is a good quality car and motorcycle battery charger that could save you buying a replacement battery if your vehicle has been left standing for a while, or even if the battery isn't fully charging any more. It won't fix a broken battery, but it can recondition older or fully discharged batteries and so could save you money.FULL REVIEW: I couldn't find my old car battery charger when I needed it recently, so I looked at a few different models of charger and settled on this one as it appeared to have several useful features at a reasonable price. It's suitable for several types of car & bike battery and has a pulse charge function to recondition batteries which, like mine, have been discharged for a while.My car uses a start/stop battery which is an AGM type rather than a normal sealed lead acid battery, but these are more expensive to replace and need to be registered with my car's Engine Control Unit if they are changed. In both types of battery, it's normal for lead sulphate crystals to form whilst the battery is discharging and then dissolve as the battery is recharged. When a battery is left at a low charge for a while though, these crystals can harden and make it more difficult for the battery to hold a full charge - which is when a pulse charge is useful because it can dissolve those hardened crystals and recondition the battery.The charger itself is quite light as the main component is its small power supply which sits at the bottom of the orange plastic case and is fan cooled to stop it overheating. The battery clamps use thin wires that are designed to be pulled apart carefully so that each clamp is then the right distance apart for your battery or, in my case, the jump start/charging points under the bonnet. I must have read the user manual 3 or 4 times before using it because it's not been translated very well and a few bits of information are either missing or wrong, however it is quite simple to use and I'll share what I learned in the process of reconditioning my own battery.Like most chargers, you connect the red clamp to the positive terminal and then the black clamp to the negative terminal, then wait a moment and it will tell you the current charge state of your battery in 25% increments. If you then plug the charger into your power extension cable it will instantly start charging the battery using the first setting which is Car for normal sealed lead acid car batteries. Clicking the button on the centre right of the screen allows you to cycle through the other charging options which are AGM (start/stop batteries), Moto (motorcycle) and Repair (pulse). One thing not mentioned in the manual is that the Car, AGM & Motorcycle modes all start off displaying dES on the screen for a few minutes which is the desulphation phase of charging a battery before they then switch to the normal charging screen where the battery level indicator fills and drops whilst the numbers rotate through the temperature voltage and amperage of the charging session. Once a battery is fully charged then it will switch itself off and display FUL, and it has a built-in safety feature that turns itself off after 15-16 hours to avoid overcharging and potentially damaging the battery. However, it's always possible that a damaged battery won't be detected properly and so could overcharge causing a fire, which is why the manufacturer recommends not leaving it unattended whilst in use for long periods of time (i.e. overnight).I personally tried charging my battery over two days for between 8 & 12 hours each day, checking it every 20 minutes at the start and then around every 2 hours or so throughout the day. Although the battery charge level improved by about 25% each time, it never fully charged and wasn't holding that charge overnight so I then tried running in repair mode. The manual recommends running a repair for a minimum of 8 hours for a car battery and 5 hours for a motorcycle battery, and that a full repair cycle should be complete in about 20 hours. I ran this repair mode for 8 hours the third day and 12 hours the fourth day, then on the fifth day ran a normal charge cycle which finally fully charged the battery after just a few hours and stopped itself charging just like it's supposed to do. I checked the battery power level again the next day and this time it had held the charge.This pulse repair technology used to only be available on very expensive car chargers and is a built-in function for some military vehicles, so to have it now on a cheap charger like this one is fantastic. It's saved me having to pay a couple of hundred pounds for a new battery and I intend to do an 8-hour pulse repair on my battery a couple of times a year from now on to keep it in good condition and hopefully prolong the life of the battery.

Fantastic value for the specification, I got this to try and revive a dead AGM battery that my Halfords smart charger plus said was no good, AGM batteries need a different power initially to get the charging process going, this is why my Halfords one wouldn't work,vas it couldn't detect the AGM ,I put this one on and it brought it back to life in a day and a half, this is on a big battery for a jaguar xkr, very impressed, it has lots of modes and will support different battery types, once you have selected the mode you want, it just automatically goes through it's cycle, and will tell you when the battery is full, for under 20 quid it's well worth it, like some of the other comments have said the leads are a bit short, but that seems to be the only minus point, the quality of the housing is even pretty good, the display back lighting is a little bit dim, but you can tell what's going on,the manual, explains the messages on the display, which are abreviated , overall great value, and well worth the money.

Started to get issues with a car battery which had needed jumping three times recently. After the first time the car wasn't really used and only did 2 5mins journeys in a month. Next time it, it only lasted a couple of days. The battery was tested at Halfords and found to have no fault, but immediately afterwards it wouldn't start. Purchased this to provide a full recharge. used the AGM mode as advised by Halfords engineer and 10 days later car wouldn't start. Researched a new battery and found to be EFB! Put the battery on charge which took 4 hours, then ran a repair on it, which takes a long 16 hours. Happy to say (so far a week later), the car battery appears to be fine.Pros: Easy to useSizeBuild qualityCons: Lead length is very shortInstructions or lack of!Yes I would recommend.

Apart from s slightly too short mains lead the whole charger was easy to use. Was not too noisy from its cooling fan.The charger was purchased to charge the battery on my laid up car, sorting it out for the MOT. The battery was not totally flat at about 20% charge (according to the display) and it started its routine. I was amazed how quickly the battery was restored to full charge. I would normally expect to be waiting for at least 24-36 hours.The whole device is a reasonable size and tucks neatly against the wall. But is easy to see and not trip over/ kick.I am delighted at the speed of the charge going into my battery, the informative display but as I have mentioned the mains input could be a foot or so longer. It was also nice to get a proper UK plug on the end not the normal death plug on Chinese built items. I am sure that a competent electrician could replace the mains cable if needed.The red and black colours make this look the ‘business’ with the blue LED’s and Green display contrast nicely. The unit is not too heavy compared with more conventional chargers and is as smart as anything that has been to college.Overall I would recommend this charger, not too expensive but feature packed, does exactly what it says it does.

Great quality and design, impressed with how quickly it changed my battery. Easy to use and one of my best buys this year.

I use this for my motorcycle in the garage and it's TERRIFIC. Acts as both a trickle charger and a full-charger, I can't recommend it enough.

Works as expected. I like the display size and brightness that allows me to read values from a distance in my driveway. I would have appreciated if both the charging cables and the power cord were longer than just being about a meter in length.

Small, smart, easy to use. Seems good value for money
