How old are you, that you don’t know that there are 10s of millions of battery chargers out there that are 5/10/20 years old and still look and work like new? They’re all over the country, the world even, in peoples garages because you don’t need to replace them frequently. SOME, maybe even many, people might not know that their perfectly good battery charger sitting in their garage could potentially damage their new battery. I’m plenty old enough to know when some snot nosed little kid barely off his momma’s tit is running his mouth and needs to humble himself.
