Chances are you’ve heard the expression “marry your batteries” if you’re a vaper. Marrying your batteries means pairing the batteries that you intend to use for a particular device and keeping (and charging) them together. Generally, you will have at least two such married sets: one set that you are actively using, and the other that is charged for when you are ready to switch them out.
But why do you marry your batteries? Why can’t you just use whichever batteries happen to be lying around for any of the devices that you are using? In order to keep your batteries at roughly the same point in their life cycle, you want to be charging and discharging them at a roughly the same rate. This is why you marry batteries to each other (batteries needn’t be married to a particular mod).
For example, say you’re using a married set of four 18650s in your Hammer of God. You then decide to use two of those batteries in your dual battery device and use one of the batteries in a single battery mech tube, leaving one battery to the side. All of those batteries are being discharged at a different rate. When you collect all four batteries to use in your H.O.G. again, they will be at different points in their life cycle.
You can, however, use a set of married batteries in one dual battery device and then use the same pair in another dual battery device. Why? Because they’re still aging at the same rate: they’re charging and discharging at the same rate.
Another common question about married batteries is can you split them up for use in different devices? The answer is yes, you can. Your batteries can be used separately from each other. But the “divorce” is final, there’s no remarrying batteries once they have been split off and used separately and charged/discharged at different rates.
