Using battery trickle charger over winter

Post by Oakleyextreme » Tue Nov 17, 2015 10:47 am

I've bought a bmw charger to use over winter but was wondering do I lock my zed or leave it unlocked as I'm not sure if the charger will set off the alarm?
I would think I should be able to lock my zed without any problems but wondering if anyone else has experience this.

my charger is connected direct to the battery, i have a mains cable in the boot and the boot is closed, no problems with the alarm at all

Same as Taz, CTEK charger in boot connected directly to battery, mains cable running out under boot lid.

Car is garaged and locked but with the boot lid down but not latched - I don't think the alarm activates until both doors and the boot are shut/latched

Interesting - does the car actually fully shut down if you leave the boot partially open?
For the reason of not trapping the cable I connect my set up under the bonnet on the first catch.

The cable does not get damaged when it's trapped under the boot lid, only a slight compression mark is found on the cable

I get that and have done similar myself. My question was really of PerryGun who indicated he leaves the boot open.

I'm pretty sure that the car goes into it's 'sleep' state - If I unlock it and turn on the ignition you can hear the pumps prime and the satnav shows the boot screen which, AIUI, it only does if the car is 'waking up' from a full shut-down state. I think it treats it the same as if you pop the boot using the remote, that doesn't seem to wake up all the systems either

Although with the CTEK connected it wouldn't really matter if it didn't fully shut down...

I have the E89 zed so on shutting the boot it electronically latch down.

I was thinking on connecting to the battery terminal leads under the bonnet then dropping the charger cables down to the floor so bonnet close as normal.

That would be the best method by far.

One thing Taz I would recommend unwinding all of the extension cable when in use.
I know it's only a small current going through the cable but it could get hot coiled up.

If you had a long enough extension lead this method could also let you drive to the local shops without disconnecting the charger :rofl:

I trickle charge to the under bonnet points but feed the extension flex (with single outlet ) into engine bay near the wipers so i can close the bonnet properly without it trapping
I don't like the idea of a crushed or trapped lead leading to a possible 240v car :o although it is plugged into circuit breaker as well

I used to forget mine was plugged in! :oops: and on a few occasions I have driven out of the garage and ripped the cables apart but luckily each time I managed to fix the connections without too much of an issue.
