If I want to use a maintenance charger over winter can I plug it in to vehicle battery and let split charge relay charge both batteries

I haven't got an onboard charger, the split charge relay is plugged into the vehicle battery terminals. If I charge each battery separately using independant chargers will they interfere with each other as the batteries are connected. The split charge relay opens when the voltage is above a certain threshold.
I am confused!
If you don't have an on board charger what charges your leisure battery and what happens when you plug into the mains.

one way round this is a flying lead between the two batteries and a single charger....a long wire with an insulated crocodile clip each end and clipped to the pos terminal of each battery.
the two batteries will share a common earth, probably through the chassis.
if you do this, then please fit a 10a fuse at BOTH ends of the flying lead,
if the wire has a single fuse and is damaged and earthed then the fuse will blow but the other, unprotected, end will still be live and to earth possibly causing a fire.
dont forget to remove the lead before starting the engine or the fuse(s) will blow
