Heya all, Ive just got a little q that im hoping someone can answer for me

Since i wasnt sure which kit i was going to prefer when i started vaping, i ordered 2 starter kit types from the TW website. a Wicked Tornado E-NIC Compact Starter Kit and also a 510 Titan Tank E-NIC Kit.
The titan batteries charge fine, red light shows, and when full it goes green. But, im a little confused with my tornado batteries (and i threw away the instructions that came with the kit doh!)
The light when the tornados are charging stays green all the time. the button light did flash on and off for about 5 seconds after it had been charging for while. Does this mean it done? Its gone back to not flashing again and the light is still green.
The charger is a 420mA and the battery is a 650.
Edit: scratch that appears my USB hub has a glitchy socket, tried using one after its been on for ages, hadn't charged at all, so switched to a different USB and now the lights gone red *sigh* why didnt i try this earlier
