One of the pairs of 18650s for my Vape mod. When they're reading low on the Mod.
I put them on the external charger. They start at 3.5V and then almost immediately jump to 3.8V.
They're LG HG2 and I've had them for quite some time. They may be 2+ years old.
I have a bunch of batteries for my mods and rotate them in as I use them and recharge on a external charger.
I use pairs of different brands for different mods so it's easier to track them.
