The discount store type battery charger, while possibly (probably) being microprocessor controlled, uses lower quality components and cooling methods, as they are designed with low cost and occasional use as their primary design criteria. The industrial units have higher quality components and heat management in the design, and most (all of the chargers we carry) are rated with a 100% duty cycle, which means they can run at full amp capacity for extended periods. They tend to be more expensive, but generally not excessive.
Some of the discount store type chargers specifically say not to use them in a daily use or industrial environment in their owners manuals. We will not carry a battery charger that says something like that. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
