My NOCO G750 charger/tender started to melt and was too hot to touch. Manufacture date 2013... So it's around 5 years old. I really think this is a safety issue and if you use one keep this in mind. I contacted customer support and described my issues with pictures. This is their response to the pictures I sent in:

"No, they do not worry us as our units are working as designed if that happens. The fire suppressants and non combustable housing are made to melt like that if there is an issue with them. If they are getting hot to the point of "melting", there is an issue with the charger, but that reaction is exactly as designed to meet the safety regulations we have for our products."

I don't consider a 5 year old charger too old.
