@Zombo - Some people stress over the charge of their
batteries, and some do not. I use red AWs from RTD (known to be the real thing) - I do nothing special other than have a *good* charger.
I either use a battery til dead (ProVari starts blinking-dead), or until I go to bed, whichever comes first - then the battery goes on the charger and stays *in* the charger until I want to put it in my mod - which means overnight, or if I am gone, etc - other folks worry about fires, etc - so they only charge when they are in the room to watch, and then remove as soon as they are done - /shrug...
My point is; I bought my P2.5 DEC 2112 and ONE 18490 and ONE 18650. 490 gets used every single day, and the 650 is put in on any day I am gonna leave the house with the mod (when I get home, switch back to the 490 and my Tatro base) - am still on those first two
batteries, which is 400+ charges on the 490 for sure.
So, if they both died tomorrow, I would be pleased with the life I got out of them. Now, since my new P3 is due soon, I did order 3 18350s, and 2 18490s, and 1 18650 (new model, red AWs) from RTD and they have already arrived and all went on the charger for least 12hrs.
That's my story and my plan. May or may not be the best way to handle them, but it works (so far) for me.
I have two of the two-bay cheap chargers from ProVape - and actual
reviews say they are good chargers - FYI "Tenergy" TN270
