6 Volt Battery Charger

Begins its charge cycle on fast-charge, providing the battery with constant voltage of 7.5VDC, and regulated current of 500mA. This charge cycle is indicated by the red LED. As the charging cycle progresses, the terminal voltage of the battery will rise to an eventual 7.5VDC. At this point, the charger senses this voltage, and the fast-charge circuit cuts-off, also turning off the red LED. The float-charge circuit then comes on along with the green LED, providing the battery with a constant voltage of 6.9VDC.
This charger can be left on the battery indefinitely without damage, and keeps the battery fully charged, ready for use at all times!
