I bought this charger 2 yr ago and I love it. It has a 15, 8, and 2 amp charge setting. Digital readout. Maintenance mode once the charge is complete. It also lets you select the type of battery. Here is my issue: it recently started making a high pitched sound when operating. It seems to still function but it makes me nervous that something isn't right. It sounds like a bearing or something could be bad? Any idea if this is ok to continue use or should I see if the co will repair it?
