Hi

Purchased another battery for my 46 M3 vert today.

I use it once a week if that, what’s the best device to keep the battery topped up without damaging it?

Thanks in advance.

Buy a CTEK conditioner. https://batterygroup.co.uk/Accessor...Y2ej43uu28WyW4AjvHIU0ZKmvSNlJ0YgaArezEALw_wcB

You can fit the push-in adaptor very neatly to your battery with the plug just exposed over the boot trim.

Just plug it an and leave it... it will charge till battery at optimum voltage then monitor.

Yes you can close the boot whilst plugged in (the boot seal will compress enough to allow the lead to pass).

Just remember to unplug it before you drive off! (put something on the roof of the car to remind you?)

Brilliant! Just what I need! Really appreciate it.

Quick question…….. because I reverse into the garage and the plug socket it at the front, would it work with the charging points in the engine bay?

Thanks again guys.
