Operation Highlights
Charger provides constant current.
Charge time - 15 hours. A RED indicator light will be continuously on while charging. After charge cycle is complete, the light changes to GREEN and a trickle current is keeps the battery pack at full charge.
A sequence of flashes will detail charger type and the internal code version when power is applied.
While connected to USB power, indicators flashes briefly every two seconds as it looks for a battery to be connected.
Once the battery has been disconnected, it continues to search for a connection.
If battery is disconnected or power removed, charger will restart the charge when reconnected or repowered.
Power Requirements
Charger receives power from a USB charging port through a micro B connector. A standard USB charging port can supply 500mA which is sufficient for all charging modes.
Other power supplies, computer USB power or cell phone chargers may also be used, as long as they supply the 500mA necessary to power the charger.
NOTE: If sufficient power is not available from the power source, charging will stop and the red light indicator will flash rapidly.
Power Charger Status Indicators
Brief Flashing RED (at 2 second intervals) - Powered, waiting for battery to be attached.
Fast Flashing RED (off/on once per second) - Error (Low supply voltage or shorted battery).
Continuous RED - Charging.
Continuous GREEN - Charge complete, trickle charge rate.
