LED indicators: A blue LED indicates power to the unit. Indicators are green when the battery is fully charged, red when the battery is charging, and flashing red when the battery will no longer accept a charge.
Note on most cheap chargers: Typical cheap chargers use a timer and do not charge individual cells evenly, or at all, or have no timer and will damage them if left in too long. They typically will only charge 2 batteries at a time and they must have the same charge, use a bulky wall adaptor, or plug directly into the wall, requiring you to stoop down and remove all other plugs from the socket and usually will only accept local power (120v).
