E30 Zone

Hi,
Im putting the e30 away for the winter and have bought a ctek battery charger mxs3.6,is it ok to leave it on trickle charge throughout the winter months constantly or just charge it once a week now and again+any other tips on what to check on during winter months?
Thanks

I have a cheaper alternative and I charge the battery fully, then leave it disconnected, connecting on the few occasions it's fired up during the winter months.

the Ctek chargers are designed to be left connected - it will be fine. Once the battery is fully charged it automatically switches to "maintenance" mode which keeps it at full charge.

The charge you have is similar to mine and it's fine to leave it connected. I didn't think it was a good idea to disconnect the battery as this screws up the cluster batteries..?

Thanks
