I have also heard of guys never having theirs turn green… doesnt seem any better than my old vx-1P charger with no light. It sucked to have to guess when it was charged and risk overcharging it since the charger had no float.
Best purchase I’ve made for it was to buy a battery tender junior. I payed $25 for it and man what a difference. 3 stage charging with a float and maintenance mode. After 3 hours of fishing with my vx-1 the battery tender jr has it charged in about 1-1.5 hours. Better yet it also works on motorcycle and ATV batteries.
Later I’ll snap a picture and show how I have mine rigged up with the tender leads mounted so I can plug and go.
