i think its normal. is there a percentage chart at the side of where you slide in your battery on the charger? if there is, if it blinks twice it means 50% charged, thrice means 75% charged. If it turns green and lights up permenantly then its fully charged. Pardon me if i'm wrong
Thank you all for the help rendered. Just confirmed that it is normal. Sorry am a noob in this as I have been using xxxD series and PnS all the while and the charging light is totally different. Will close this thread now.
