Automatic Car Battery Charger - £12.99 @ Lidl

12 / 6 V Car battery charger. Fully automatic so allows you to leave it connected and it'll take care of keeping the battery fully charged!

Looks similar to the CTEK units that seem to retail for around £45.

these are good - got one last year when on special and ideal for keeping caravan/boat batteries float charged
#2
If your car battery needs recharging.... check the battery fluid (distilled water), buy a new bigger cranking Amp battery, get the alternator checked out or switch the lights OFF at night when you park-up.
#3
They are good, I bought one a couple of years ago. ;-)


mr_porkbelly is quite correct, they are almost identical to the CTEK units.

If you look at the buttons and led's they do very closely resemble the ones on the Ctek XS 3600 charger which costs around £40 minimum, the same power output too..

Do you guys think if that could work with a scooter battery as m battery always goes flat when not used for 2 days!

If your scooter has a 12 volt battery it will be ideal.

There're 3 modes of operation, there's one with a picture of a motorbike which is for 12 volt batteries with a capacity of less than 14 Ah ( which a 12v scooter battery should be).

I use one of these for my motorbike and they work well.......

Thank you for the info. In this case, i might get myself one from the nearest lidl shop if they have one as they usually have nothing! I was gonna get one from Halfords for £19.99 but now i wont...

I have one and agree they are excellent. Use on a classic car which doesn't get used all winter. Battery is now 12 years old! I do disconnect the battery but I suspect they are just covering themselves as they don't know and can't control the circumstances of use. It's actually the car manufacturer's recommendation you should seek.

I have one of these, and a CTEK. They're possibly similar, but certainly not the same. The main advantage of the CTEK is that nowhere in the manual does it require you to disconnect the battery before charging. The Lidl one does. That's the big advantage of the CTEK, because disconnecting the battery on a car (which they're very useful for trickle charging) may well cause the immobiliser etc to lose the 'memory' and have to be reset by a garage.

Good deal. When was the last time anyone saw a 6v car battery though?!

These have been made to look and operate like the CTEK Units but they might not be the same...

A few months ago I was looking to buy a new Battery Charger and in the end personally tested 6 different battery chargers amongst 4 different batteries both car batteries and the kind used in computer UPS systems

I also tested one from LIDL and also a CTEK charger on some 12 volt batteries that were pretty much dead and showing very low voltage, I think in some case almost totally dead.

The LIDL one and the other 4 didn't do anything - but the CTEK one got what was a dead battery up to about 8 volts.

That wasn't enough to make the battery usable but at least the CTEK was able to get the battery much further along then the other 5 I tested.

Don't be fooled by the fact it looks like the CTEK, it's not the same thing on the inside.

I'm sure if all you want is something to top up a car battery then most chargers are fine but if you're looking to revive an older battery this probably won't be as good as a CTEK. This model appears to be very similar to the LIDL model I tested but looks slightly different and I don't believe the one I tested could do 6V batteries so this maybe an improvement on what I tested.

This charger can be used to charge 6v motorbike battery's hence the 6v option :whistling:
#15
I got one for the caravan over a year ago and its been great. They are a bargain, loads of good reviews on caravan forums... But in the end I bought the CTEK as well:)
#16
I'm off to pick one up in a bit, and will compare it against the CTEK I've currently got (nicked off my dad, so should really give it back). Not sure why they recommend you disconnect the battery though, but that does seem to be not as useful as one that could remain connected.

Small motorbikes, classic cars, etc.

See post above - you'll find they're not the same, and that the instructions are quite different. :)

i have a ctek charger and a halfords maintenance charger , i left the halfords one permanately connected to a motorbike battery and after a week it fried the battery , the ctek on the other hand STATES can be left permanately connected as it comes with hard wire connectors , simply un plug and ride off when u want , the ctek has splash proof connectors and charger body , it also comes with a 5 year guarantee , i looked in to these as opposed to a optimate 4 charger which are £50 and the ctek was rated as a much better charger , ALSO DONT BUY If YOU WANT A QUICK CHARGER THESE ARE DESIGNED TO EXTEND THE LIFE OFA BATTERY AND CAN TAKE UP 3 DAYS TO CHARGE AND OPTIMISE A FLAT BATTERY. the lidl charger may well be a great charger but it doesnt come with hard wire connectors and no where does it state you can keep the battery connected for months , which is vital for motorbikes if there not used on a regular basis

I own 4 cars, and over recent months 2 of the cars have had occassional flat batteries.

One's a 3litre petrol, and the other a 2 litre diesel so they are both big batteries.
Alternators are OK, and batteries are less than 1 year old, since I only replaced them last year.

I had an identical looking charger to this [with an inline 7.5 amp fuse - on a 4 amp charger?] and it would not even start to charge either battery if the battery was completely flat. It would charge the battery following a jump off from another vehicle but not not once the battery was completely flat, in fact it just blew fuses.

Installing an inline ammeter, and disconnecting the battery from the car completely I could see that the battery was drawing 8 to 10 amps for the first 30 seconds to 1 minute following connection, hence the blown fuses.

Bought a Wolf Starter/Charger [320AMP] from ebay in the end, used it once and neither car has let me down since??? I mean I've never had to recharge the battery again? Strange and I can't explain why, but even in this recent cold weather and not driving one car for 8 days it started first turn.....

Anyway, point I'm making is if you have a big battery on your car, and the car has a big engine, and it's completely flat this charger is unlikely to get you going again - buy a higher current charger [8 / 20 / 30 amps].

l would like to know if this will be ok for my car BMW 318ti Compact 2004. Do any of you know if all car batteries are a standard 12v? Not much of a car tech and unable to get to my car at the moment to find out, and have been looking all over the web for the info on my car with no luck.

Sounds like you probably need a new battery if the current one will not hold charge for longer than 2 days.

If you regularly leave your motorcycle unused for long periods (like weeks) consider getting an Optimate. Not cheap, but not only charges batteries but maintains them too.
(You'll probably find them cheaper than the link I provided though!)
It also is provided with all the necessary links to allow you to wire up a discrete connector to aid easy connection/disconnection without having to actually access the battery each time.
You can safely keep the Optimate connected for months and it will maintain the battery in top condition.

Edit: Appears similar to a ctek unit others are discussing.

Note: an automatic battery charger is not the same as a specialised device designed to be connected to a battery possibly for months on end when the item the battery is connected to is not used regularly.

The Lidl unit does do a maintentace charging mode automatically, that's designed to keep batteries topped up through prolonged periods of non use.

Maybe this charger has too high a ripple voltage? - The CTEK charger we have claims :- "Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 - 400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery. The MULTI XS 3600's ripple is only 2%. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery."

I think any similarities are purely cosmetic.

I think most modern sealed car batteries (AGM / silver calcium) are supposed to be charged to 14.7 volts, and the old fashioned non-sealed batteries are charged to a maximum of 14.4 volts.

This charger should do both as it states on lidl's site "Suitable for all 6V and 12V sealed lead acid batteries including wet, gel or AGM batteries (1.2 - 120 Ah)"

Got 1 a couple of years ago for my motorbike and I just keep it connected all winter.
Bought 1 yesterday for a water pump at work and paid £15.99 for it from Lidl in Coleraine,Northern Ireland,robbing gits!!!

Just because it says automatic, doesn't mean it is designed or suited to be left connecting charging the battery for prolonged periods.
The automatic charging programme of the opimate is just one part of the overall process it uses.

They seriously expect people to send Credit Card details via email.. yea right.

Oh and it seems nobody has told them that VAT is now 17.5%.:)

But the Lidl one, according to its instructions, MUST be used only when the battery is disconnected. The CTEK can be used without disconnecting the battery, with all the downside that can bring.

Yeah I'm not in disagreement over the fact it states it should be disconnected. Most of the car's I'll charge it on won't make a bit of difference if the battery is unhooked. But your right in saying it can cause problems with radio code etc. Most people don't realise you shouldn't clip the CTEK unit straight onto the battery when it's connected to the car.

thats the whole point of the ctek style charger that u can leave them connected. thats why unlike a normal battercharger ctek chargers come with a hard wire (permanate connection kit)

hot deal, thanx

Amazon do a £4 trickle charger that did the trick for merecent and hasn't beurnt my garage down like the feedback.

Excellent things these. Especially with the cold weather will be an idea to give your batteries a decent charge. For this price you cant go wrong and its a small price to pay to add to the reliability of your vehicle starting and will prolong the life of your batterie
#40
These cheapo chargers are nothing like the Ctek chargers. The top of the range Ctek 7000 costs from £70-£100 and they are a lot more advanced than these pieces of rubbish.

If you have a totally discharged battery or one thats in ill health and needs reviving one of these will be no good at all. The ctek will also charge batteries up to 100Ah and has loads of different modes of charging to ensure its kind to your battery.

Yea for the price they work well as a battery charger, but you can't compare them to the Ctek chargers, its like chalk and cheese
