heffergm Posted September 24, 2016 Report Share Posted September 24, 2016 The charging block for my Oset occasionally makes odd noises when plugged in, almost like there is something mechanical inside it grinding away. I'm pretty sure it's always done this, but not positive. Normal? Quote Link to comment Share on other sites More sharing options...
sirdabalot Posted September 25, 2016 Report Share Posted September 25, 2016 If there's a bad connection it could be arcing, check to see if it's hot and for signs of scorching/melting. Quote Link to comment Share on other sites More sharing options...
heffergm Posted September 25, 2016 Author Report Share Posted September 25, 2016 Nope, all normal. It's a pulse charge charging block for lead acid batteries fwiw. Quote Link to comment Share on other sites More sharing options...
heffergm Posted September 25, 2016 Author Report Share Posted September 25, 2016 Should mention it only does this as a discharged battery is being charged. As of nears full charge it lessens then stops altogether when done charging. Quote Link to comment Share on other sites More sharing options...
gwhy Posted September 25, 2016 Report Share Posted September 25, 2016 is there a small fan inside, these over time can start to make some very strange noises.. Quote Link to comment Share on other sites More sharing options...
