I have a 12v/5A IP65 Charger which has been used to keep cars not driven often topped up.
Today noticed that it was making a relay click sound about every 10 or so seconds and when viewing the volt/amps on Connect App, it showed it the currrent was droppiing to zero every 15 seconds (approx) which then lasted about 5 seconds before the current would pick up to about 0.3A (during this clicl cycle the voltage seems to rise and fall about a range over 0.2v. It has been doing this today for about 2 hours so far today.. I've had the charger about 2 years and never heard it making noises so frequently as this. Should I make a warranty claim?? If so who do I need to return to in Australia? It otherwise seems to be charging somewhat normally.
