Just thought I'd share my thoughts and findings on the following.

I've had previous versions of Lidl's and Aldi's car battery chargers in the past, and I've just bought and tried Lidl's latest version. I'm delighted with it! The backlight remains on (so it's easy to view the digital readout immediately, at any time during the charging process, without having to press any buttons; the charger runs cool (unlike previous versions); it has a sequence of charge phases, as well as maintenance charge (ie keep the charger permanently connected during long periods of car/battery 'no use' (eg winter months)). True, the maximum charge current is 'only' 3.8 amps, but that is more than adequate for home/domestic use (and the Lidl charger cannot be compared to, say, an expensive Accumate).
But I've tried the new Lidl charger on three dubious car batteries ( I admit to being a bit of a car battery fetishist LOL). Two batteries are now charged and confirmed 'good' and the third battery's condition (that I know is past its best) is confirmed by the charger's voltage display/sequence.
For anybody who wants an inexpensive 'winter/standby/maintenance' charger, I recommend the above charger. But it is a Lidl 'special' which starts today (Thurs 27 Sept 2018), so you'd better get to Lidl in a hurry if you want one.

If any lead acid battery has been left discharged, it will have suffered from internal chemical deterioration called 'sulphation' (where lead sulphate crystals will cover the internal lead plates). The only way to reverse that scenario is to use a pulsed high voltage de-sulphator on the battery (and/or, for a short term fix , use EDTA crystals in the electrolyte). Having said that, the posted Lidl charger has a compromise 'charge phase' where it senses a battery of voltage 7.3v - 10.5v, whereupon the charger tries to establish if the battery is a 6v device or a 12v device, and will apply a recovery 'pulse charge' low voltage (which is not a desulphation process). *** If the Lidl charger detects a battery voltage below 3.8v (or above 15v) it will show 'Error' and be electrically dormant.***
In summary, the Lidl's 'recovery' process is a compromise where it tries to recover a working terminal voltage from an out of spec battery. It will then try to fully charge the battery, but success is not guaranteed, in which case the charger will never adopt its 'maintenance charge phase'.

Have one there great.

How many amps is the charger ?
Well written review. @AnthHether001
Heat added.
It's 3.8amp

I’d bought this earlier this morning - didn’t think of putting it on here!
Question do do you really have to disconnect the earth when charging as it states in the blurb as I thought it can be a problem with modern cars with the onboard computer having to be reset?

As you allude, modern cars are fundamentally computers on four wheels. With any pulsed battery charging system (the Lidl charger has a pulsed phase of charging, if called for by its monitoring circuitry) there is a slight possibility of interference with (and/or damage to) low voltage/microprocessor circuitry (ie modern cars' control circuits). To cover their backsides from lawsuits, battery charger manufacturers advise isolating a car battery under charge so that any possible interference (and damage) with modern cars' microprocessor circuitry is virtually eliminated. The Lidl charger instructions do state 'Remove the negative pole clamp from the negative pole of the battery'. Doing so does isolate the charger from the car's circuitry.

The point I was trying to make was that I was told (can’t remember were) that if you isolate a battery from modern cars i.e. take the earth connector off, the onboard computer needs to be reset. Does anybody know if this is true or just a load of old !?*#%.....

It doesn't 'need' to be reset but what happens is it will automatically go into a learning mode if you disconnect the battery for a long time, the learning mode lasts for a few miles which I doubt you will notice when driving the car, your biggest problem will be if you have a security coded radio and don't know the code unlock it.

I don't know about resetting cars' onboard computers, but disconnecting the battery almost certainly will require you to re-enter the radio's security code to get it working again.
bought one of these last year, used it a couple of times and it does the job just fine

The central locking works of the cars battery so if you disconnect the battery the central locking will not work until you re connect the battery.
It will not need reprogramming afterwards though and will work just fine after re connection.

Did you disconnect the battery
Thanks, just picked one up.

nope
Perfect timing, battery dead this morning. Lidl was a short bike ride away, still had a few in stock. Battery out and on charge now
Cheers
Anyone who has bought one and not tried it yet I suggest you give it a go because I just bought one and got it home, plugged it in and pop the house electricity circuit breaker trips out and a burning smell comes from the charger also the chargers plug fuse has blown, replaced the 3A fuse and the same thing happened again.
Funny though because the Lidl I bought it from in Liverpool had a few open boxes that looked like they had been returned and put back on sale.
Returning it tomorrow but weary about replacing it with another especially as the Lidl is a fair distance from my house.

I know it’s been sometime since your post, I bought one and need to use it now. As someone who seems to be in “the know”, do you disconnect the battery when charging? Thanks

The instructions that come with the charger state 'Remove the negative pole clamp (black) from the negative pole of the battery'.
As previously posted, the reason the battery charger seller/manufacturer state that is to protect themselves from possible legal action should the battery charger damage any electronic systems on the car (disconnecting the negative or positive terminal electrically isolates the battery and charger from the car's electronic systems).
However, AFAIK, most car owners don't disconnect any battery terminals when using a charger. But there is always a small risk in not doing so. (Bear in mind that disconnecting a car battery from a car can lose/reset some car electronic systems , eg radio security code, electronic window pre-set, etc).
