I bought a MFLB yesterday after buying a PALM vaporizer last weekend that diddnt live up to my exspectations. But i have my batterys on the charger and they have been on there for a while now and i thought the lights were suppose to turn from red to green but there just staying red. Its been on the charger for like 2 hrs.
Lights will eventually turn green. In the manual it says that it may take up to four hours for a complete charge. I have found mine have never taken this long but could vary.
