Question:
We purchased a set of Malibu Solar Lights w/ malibu solar batteries (what a surprise :) ...) anyway, we charged batteries prior to usage. Since then, battery power has diminished in matter of days. Any ideas why? As an aside, we purchased same type last yr, stuck in ground w/o charging first and no problem since. Now it couldn't be that blatant! "Let the sun do the charging. That's what solar power is all about." If that's the solution, I understand. Yet why then would the freshly charged new solar batteries run their course in matter of a few days?
Answer:
It could have been just the quality of the batteries. The manufacturer of your lights may have several sources for their batteries.
Nickle cadmium batteries have to be completely dead before charging, other wise degrading their holding power. Silver cadmium batteries can be charged at any level.
