Hi - I am using my new USB Multi charger for the first time to charge my new KR808 battery for the first time. The light on the charger is mainly red, but flashes blue about every 6 seconds or so. It has been doing that for a couple of hours. How do I know when it is done? How long should it take to charge one standard manual battery? I should mention that both the battery and the charger came from LiteCig. Thanks very much for any information that anyone may have!
