When to swap batteries?

[burtonsnowww]

i vape on my grand as my daily device and throughout 24 hours i go through about 3-4ml, i also use various mods inbetween the day while sitting at home but i always change my 18650 around the same time each day and i also always have a backup incase i feel the battery power is too low

I like to play the guessing game when I take them out and check them ........

After 3 plus years with REOs I can usually hit it within .01 or .02 volts

Most of the time mine are coming out of the mod between 3.68 and 3.73 ....... that is when I am no longer satisfied. I can go down to 3.4 in a pinch.

Sometimes when I'm really bored I just take a guess and pull it out to see how I did ... then put it back in.
Ummm 3.94 ....... pull out ....... grab doohicky ......... 3.95 ...... Yes ....... Still got it!

I have a doohicky, and test my battery with it. The battery never leaves the mod. I simply pull down the door, put the black lead on a magnet, and the push the red lead in the slot where the nipple of the battery goes. Works all the time. Course, if you are using flat top batteries, I do not know if this method will work.

I just tried it... it works... its so easy, took a second or two to get that lead on there right... but that is awesome...

im excited and scared... first day at work with my Precious...
