I have a small solar panel which I use to keep a 12V truck battery topped off. It has the following specs (in bright sun).
24Voc
5 watts
350mAmps @ 15V
The actual wall charger for the 18V battery NiCd Firestorm says it produces 21.75Vdc @ 210mAmps
The panel was designed to trickle charge 12V car batteries. What would happen if I connected this solar panel directly to the 18V battery? Could I damage either my solar panel or the NiCd battery? What about the blocking diode, would they work at 18V? Does my panel even have the ability to charge an 18V battery?
