So my first AW IMR 18650 2000mah I got bout 3 - 4 months ago. Used it as a backup for my eVic before my mech mod 2 months ago. Use it till its about 3.6 to 3.5 volts then slap it on my Intellicharger i2. I normally verify the charge and check it on my multimeter and like clockwork they come off at 4.2 volts. This morning I put my AW mentioned above and let it charge. Later that morning I look down and none of the charging lights are on. I pull it off and check the volts, and it said 4.8 volts, and was slightly warm. I let it cool, and rotated it into my mech mod to get it under 4.2 volts. Well tonight as I go to bed its still 4.4 volts, not warm, but leaving me concerned. Is this just an indicator that its time to retire this battery, or should I discharge it fully and attempt another charge?
