12V/24V 10Amp Car Battery Charger, Automatic Battery Charger with Temperature Compensation, Repair/Maintains for Cars SLA, AGM, WET & GEL Lead Acid Batteries

Great buy, bought it because my Noco didn’t seem to be charging properly. After sales service at Noco is rubbish, they have lost me as a customer. Anyway, bought this and wow! I had three batteries I thought had had it and this little beauty, a fraction of the price of the rubbish customer service over priced Noco and within a couple of hours they were back to full performance! Brilliant buy.

Due to my job there can be extended periods where my car doesn't get used very much and may only do a short journey or so per week for months on end. With modern cars that "wake up" every now and again to check systems and can potentially still keep a connection to the key when it's inside make the problem worse. All of this takes it's toll on the battery and eventually kills it. My last car went through 2 batteries (luckily all changed on warranty). So, about 8 months ago the stop/start system started failing to engage on my new car, which is the ominous sign of impending doom for the battery (I'd already done fault diagnosis on it to know it was the battery causing the issue). But instead of going to get it changed this time I thought I'd give a battery conditioner a go in the hope of ending this issue once and for all. It would also allow me to help keep the battery topped off when it see's little use helping to prevent the issue in the first place. Didn't expect much for £20 but got it all plugged in a working. left it running on "repair" mode for about 5 hours and took the car for a drive. Still no start/stop, so assumed the battery may be too far gone. The next day I hooked it up again and left it for another 4-5 hours. Wallah!!! start/stop back on line!! I'm going to keep going with it as bringing a battery back to capacity can take weeks. brilliant little thing and dead easy to use.

It is a decent charger but would be better if the instructions were written by someone with better English skills. The 10amp rating means it is better for fairly large batteries. To charge thoroughly, I find a low current commensurate with the battery capacity is better but the charger does have a few charge modes. I have found that it charges fairly discharged batteries well enough and it is worth it for that. The only downside is that it is simply a pulse charger in recovery mode. It is not a high frequency pulse charger (see screenshot of oscilloscope for proof). I don't know if high frequency pulse is more effective and if so, if it is better for wet, EFB or AGM types. I tried to recover an AGM battery from 4.5 volts. My Lidl (Ultimate Speed) charger really didn't help at all despite connecting the battery in parallel to another battery to initiate charging but this charger did improve on that. After a few hours on pulse setting, the battery recovered to 12.6 volts but couldn't even deliver 1 amp current (with accompanied voltage drop). The battery in question had probably sat severely discharged for 1 year so it was an unrealistic big ask. For batteries which have been discharged for days or a week or two, it seems to work well enough though. Despite it saying do not charge batteries connected to vehicle, loads of other chargers can do this and I don't see why this one can't. It is probably just a safety disclaimer.

Having had my classic car in storage in my garage over winter I went to do a startup the battery was absolutely flat tried using a power pack and jump leads to try and start it. Tried using a battery conditioner, absolutely nothing. Started considering a new battery this battery was less than 12 months old. Bought this charger on a last resort basis. Put it on an overnight charge imagine my suprise when I checked it next morning the battery is fully charged. The car started first crank. Would fully recommend this charger as a very useful little unit to keep. And the price is excellent. Fully recommend.

I replaced my old RAC 8amp charger that finally packed up with this one which is a lot lighter and far more technically advanced. I have a motorcycle and a car, and it's good to see it caters for both. The charging cycle it goes through is great with different stages for empty batteries. It charged mine quick as well. It's much more portable than my old one, and the cable and clips supplied are good length and strong. Great value for money!

I had no idea until I was researching what I needed that modern car batteries require specific smart chargers. This one, after considerable research, is appropriate for the needs of my current car battery. It is very easy to use, the instructions are good, albeit they are quite small to read but I scanned them and converted to PDF so that I could blow them up, the only thing to remember is to set the required settings before plugging into the mains. Once this is connected to the battery you can setup the type of charge you need as the battery gives life to the charger, however, once the mains is plugged in you cannot change the settings. This does a fantastic job in charging the car battery, it can be used for other types too but I've bought this and only used this for the car. It seems to be of good quality, albeit, that I've never heard of the make. Good value for money.

Excellent! The different modes make this a versatile piece of kit. It’s a good size to fit in the engine bay during trickle charging

This is an update to my previous 1 star review. The charger works great as long as the battery has not been completely discharged. When you connect the charger to the battery it gives a voltage reading then you turn the power on and it charges the battery. I was not aware when purchasing this item that the battery must have a minimum voltage for the charger to work. I don’t know what the minimum voltage is and haven’t found it stated in the instructions. Here’s my previous 1 star review: The charger would not work when connected to the battery. I have read all of the instruction book but can’t see any explanation. When I connect the battery the charger continues to beep. I would be grateful for any explanation.

Una verguenza, el producto se ha comprado en España pero el enchufe es inglés y las instrucciones también en inglés, inadmisible que Amazon venda cosas asi. Por supuesto, lo voy a devolver

L'article ne comporte pas une fiche conforme aux prises de courant en vigueur en France. Pourriez vous m'envoyer, s'il vous plaît, m'envoyer un adaptateur pour que je puisse utiliser ce chargeur de batterie. Par ailleurs le guide d'utilisation est en anglais, alors que L'article est livré en France. Pourriez vous m’en envoyer un en français. D'avance merci.

Mine was sent with the wrong country attached wall plug. Now I have to buy an adaptor to get it to hopefully work.

Did the job for me. Revived a completely dead Hyundai i30 start/stop battery. Had to run the recovery cycle 2 times though. But it did the job. The charge still there after 2 months. Did not run it since but still juice in the battery when trying to start.

High quality and fast charging
