I have a new replacement battery, and it's been in the charger for about a month. The 4LEDs on the charger are blinking green, the battery light is off. Is this normal?
I leave my batteries on chargers at all times, I am not using. After up to five years with one and over three years with other three. Never have any problems. These are lithium and that is reason I have never had a problem. Now my old type batteries for drills an such, I remove from chargers when charged, have never at a problem for 10 years or more.
