Noise from battery charger

[Jewellbags]

Have noticed that the electronic battery charger - I assume the one that charges the leisure battery makes a slight rattling noise (I first thought it was the water heater or a water pump ).

Is this normal ? Picture attached for reference

urrently plugged in on ehu at a site and nothing else is untoward .

Our CB-516 sometimes buzzes but it's always done it and no battery problems or anything else to worry about.

Most have a slight buzz/humm when they on

Does it have a cooling fan? That could obviously make a noise if worn or out of balance.

I don’t feel a breeze from it but I’ll get it checked next week during its service

As said,probably a fan ,maybe needs some lube in the bearing.

You will only get the humming, as mentioned above, as the poor thing don't know the words..
