Leaving plugged into mains 4 weeks

Hi team!

We are leaving our 2005 swift Sundance for 4 weeks over December.

Does this risk overloading the battery or is 4 weeks ok? Im pretty sure the leisure battery doesn't have one of those smart charging things, it's pretty bog standard (similar to the one in the attached photo which is one we got replaced recently)

Which charger is it ? Make and model might help as I suspect that even with a 2005 unit the charger will go to standby/float/maintaining mode once the battery is fully charged.
