Technical query: I use a Multi XS 7000 charger permanently attached to the 12v leisure battery of a motorhome. It appears to be doing its job OK, but
clicks... this noise began a few months back as an intermittent annoyance, clearing itself within minutes, but is now more or less permanent at a frequency of c. one/  5seconds, occurring

in all charging modes.
  • Is this normal?
  • If so, why?
  • Is it a function of a dodgy charger?
  • Or of a dodgy battery (which retains its charge, and shows no signs of imminent failure.
