[AT] Solar battery charger setup

[ATIS]

I have used three of them for years on three pieces of equipment I rarely use.  I have never had them over charge and never experienced limited battery life.   I wouldn't worry about it.    At high noon with an optimally placed panel it generates 17 -19. volts.  That lasts like 40 mins. Otherwise it generates 14 volts or less which is comparable to a trickle charger..

Hook it and go.
