Hi, anyone got one of the battery chargers from lidl? On the instruction manual it says the battery should be disconnected before charging. Just wondering if the battery can be charged up while still connected to the car. I have a CTEC that I use for the Z4 and a motorcycle and swap them over once every 2 week but would be good just to leave the CTEC connected to the bike all the time.

You don’t say which Z4 model series you have…
On E89s the Lidls are a ok for permanent connection to the positive terminal in the engine bay NOT the battery in the boot.
The one negative of most Lidl (and most other models apart from CTEKs, if they are an exception) is that in the even of a mains power failure they do not restart automatically.. :tumbleweed:
I have two different Lidl ones plus other more expensive variants and they work absolutely fine…
Just set it to AGM on the buttons..

I have the E89. Why not connect straight to the battery?B21 said:You don’t say which Z4 model series you have…

The E89 (and later cars) had an IBS..Intelligent Battery Sensor that works with the DME to work out when to charge the battery and by how much..
Depending on how you connect the charger to the battery and the many cables around it you may cause issues with the IBS and hence the charging circuits..
Hence why Lidl states ‘remove battery from car ‘ type instructions…this removes this kind of inadvertent operator induced issue.
So on later BMWs the red plastic cased +ve point in the engine bay is the way to go…
Faffing around the battery area also involves risks in damaging the IBS physically which is quite delicate plus maybe upsetting the notorious rear EPB ECU..
Apart from those reasons it’s fine..
