CTEK Multi XS 7000

Missed out on a couple of words above.

Supply is only when you want to use the charger as a power supply without a connected battery.

Codswollop , Snowflake is simply a higher voltage suitable for AGM batteries , Supply gives a constant voltage of 13.2v but should still be used with a battery inline , read your manual !

supply does not need a battery to be present!! been using my XS7000 for years as a stand alone power supply as the manual stipulates.

Not quite so much Codswallop, methinks? If you are going to use big words perhaps you could spell em right too!

The idea of "float charge" is that once the battery has reached around 80% charge, the charger will change to a float charge. This reduced voltage will top up the battery to a full capacity and the battery can be left connected without damage for months on end.

But, in the case of an AGM type battery, once a full charge has been reached, there is no real reason to leave the charger connected. You are basically only using power for no real gain. An AGM battery does not "self discharge" significantly over a longish period of time. If the camper is not being used regularly, you may connect the charger to "maintain" the battery every month or so for a day or so.

I don't bother with this too much. I ensure the batteries I use are all at full charge and then leave them be, only checking them "once in a blue moon" and before the next trip.

I still don't know where you get "standby mode" from. It is not a mode available on the Cteck 7000. Maybe this is another term for maintenance or float mode?

Check what type of battery is in your camper. If it is an AGM type, Snowflake mode is the better mode to use for the bulk charging process and the charger can be left connected "indefinitely" if you wish. In Maintenance mode (the automatic final charging process), the charger will alternate between float and pulse, depending on the exact voltage level of the battery.
