Lidl Car Battery chargers again £13.99, seem to come around once a year on these, quiet a good price, mine still going strong from a few years back, word of warning though, if there anything like the previous models that wont kick in and charge flat batteries that are below around 9.5 Volts, so more of a battery conditioner really, blah blah blah, boring, humbug, 2018 already....

   .....But now for the GOOD NEWS, Tea, yes Tea, once you fuffed around playing with Battery Chargers you can now enjoy a lovely cup of Hot Tea that will stay hot courtesy of your newly charged Battery, £4.99 (Tea Bag not included).

Yep, nothing worse than a cold cup of Tea.

It's a pulse charger, which means that it's inadvisable to use it with the battery still connected to the car, for fear of damage to the ECU.

Personally I never charge Car Batteries in-situ and still connected, the Battery either comes out or worse case it takes about 15 seconds with a 10mm spanner to diss the Neg and put a bit of cardboard between the Neg and terminal just in case.

You've never disconnected or removed the battery from a R Class Merc 

If you can't charge a battery in situ why does Ctek provide a lead to do so?  My Roadster & TEM are left permanently connected to a Ctek when not in use (unfortunately for my bike that's been far too long)

A pulse charger will struggle to actually get a pulse to appear on anything connected to a lead acid battery.....particularly anything of this low a supply current. 

The CTEK are also PWM (so pulse) chargers

[STEMO]

Must be...I dunno......thirty years since I had a flat battery.

So you must be due one. Hopefully when its cold and wet and you're dressed only in your underpants.

And we`ll not even mention the Bond Bug

These are not bad for the money, but not great for all uses.

There's no issue at all with charging on the car with these.

As said, they attempt to automatically detect 6V or 12V batteries, so a battery that is significantly below its nominal voltage it won't touch.

It also terminates the charge if the voltage goes over a certain voltage, so it's no use for reviving suplhated batteries that have been neglected.

I am not sure if they enter a maintenance mode once the battery is charged, and they certainly don't remain in such a state if the mains fails, so not much use for looking after your bike / kit car battery throughout the winter. They are OK for cyclic charging of lead acid batteries, though.

If looking for a maintenance charger, you'd be better off with a C-tek, IMHO.

My last one from Lidl....you had to select if car or bike battery....

And going by the specs on the charger it will charge a flat battery by pulse charging it....

Intelligent microprocessor control with diagnostics program and automatic charging cycle
Suitable for all 6V or 12V car and motorcycle batteries, with 4 programmes for adapting to different battery types
Pulse charge for charging flat batteries
Reverse polarity, short circuit and overload protection
Operating voltage: 220 – 240V ~ 50/60Hz

[Kevin Wood]

Maybe I was impatient, but I've tried to charge a flat battery several times, and nada.

[annihilator]

have used these types of trickle chargers for years and and a basic 4amp halfords jobby for years and never disconnected the battery or had any problems,they will charge a completely flat battery but will take a few days longer.

[Andy B]

I've a few of these & a really flat battery has required a short with an old-fashioned numb charger to get them started first before the Lidl charger would charge.
