External battery charger

How many times have we heard of some hi voltage from an automotive charger killing any of our electronics, except maybe some cheap led lite that should never have been bought in the 1st place.
I also have a Schumacher charger that goes over 16 volts on most any battery I stick it on. But it has not caused any problem. Why ? Probably because it is an automotive charger made for vehicles whose electronics that can handle some 16+ volts now and then,....maybe forever. If they were to fry electronics, don't you think there would have been a recall on them ? DUH!!
I will add that I have had 2 cheap defective solar controllers pump out 17+ volts for who knows how long before I noticed it. And it hasn't hurt any control boards, or anything else that I know of.

The answer to the OP question (read his lips) is keep doing what you are doing !! Automotive smart chargers mommies didn't raise no dummies !

I have been in the automotive industry for over 40 years specializing
In electrical/electronics. I have seen high voltage (18 plus) with no harm to other systems. Here is a clip of a RV Domestic frig diagnostics manuel.

The Dometic control system will only tolerate up to 6 AC volts on the DC line. AC ripple can be measured by a digital voltmeter set on the AC scale at the main DC terminal block connections at the refer. Six volts AC or less is acceptable. If AC volts exceed 6 on the DC incoming line the power source should be cleaned up. AC voltage in excess of 6 volts will affect the processor and create erratic operation. When testing for AC ripple on the DC line put a load on the converter. The operational range of the unit is a minimum of 9.6V DC to a maximum of 22V DC. The unit will automatically shut down until voltage has decreased to 18V DC. The refrigerator requires at least 9.6V DC for proper operation; however the panel lights will continue to illuminate until voltage has dropped to 4V DC or below.

Just sayin..............
