solar garden lights improved after wintering outside


There are two different brands of garden lights with differing
internal construction, components and battery brands, sitting in the
garden outside our kitchen window.

In the first summer of operation, I was dissapointed to see them
dimming after only 3 hours of post-sunset illumination, even on the
brightest of days. I even modified one, so that the LED's schematic
position didn't arbitrarily limit the charging voltage, without any
noticeable improvement.

This spring, after spending the winter entirely submerged in snow,
they all illuminate for at least 8 hours after sundown, even after
relatively gloomy charging days.

Anyone care to speculate on this beneficial aging effect in the
generic solar light product?
