why do the lights start flashing
When the lights start flashing does that mean that the batteries are fully charged.
I'm not 100% sure if my answer is accurate, due to the fact I didn't engineer the charger, but I believe they are considered fully charged. The batteries are usually still warm when it starts flashing. My theory is, it flashes while the batteries are cooling down after the charging has stopped. The flashing light stops around an hour or so and the batteries are cool by this time.
Heat reduces the life of the battery, so it is better for the battery's life if you charge it slower and let it cool down before using it. If you were to use the 15min charger, the batteries get almost too hot to touch. With that charger the fan continues to run for a period of time after the charging has stopped. This is my reasoning for my thoughts above.
