I picked up a Ryobi CTH1202K2 (drill, battery, charger, and case) via Freecycle, and was informed that the drill was not operating.
So, I "charged" the battery and, almost right away, the Charge Plus (yellow) light and the Fully Charged (green) light came on. I left it in the charger anyway for a few hours, with no change in the lights. Plugged the battery into the drill, and nothing, zero, nada, zip. The charger itself has this on it: "Yellow Green 'ON' over 15 min. See manual." The manual did not come with this.
Before I go and buy a new battery for this, is there a way to determine whether the drill is operational?
