Chargers: What batteries to use.

Posted by HB Vapour on

We get a lot of questions about the which charger you should use for each type of battery. When considering a battery charger you should make sure that the battery fits well in the charger without damaging the wrap or the insulator during insertion/removal. It’s also really important that you don’t leave your batteries unattended while they’re charging, and don’t leave them on charge once they’ve reached a full charge.

Before we tell you what battery fits in which charger, it’s best we tell you what the battery numbers actually mean. They have nothing to do with the watts, or amperage of the batteries, the numbers are actually the dimensions of the batteries. So 18650 batteries have a diameter of 18mm and are 650mm long (consider my mind blown when I found this out). Same goes for the 21700’s, they have a diameter of 21mm and are 700mm long. So the first two numbers correspond to the diameter of the battery and the last 3 numbers correspond to the length of the battery. This is why it is so important to have the right charger for the right battery. The battery should fit into the charger space without needing to be forced, it also shouldn’t be lose in the slot.

Some charges that we’ve listed as a “NO” barely fit the cell and we believe that it is too dangerous to list them as “YES”. There is a high chance of damaging the wrap and the insulator during insertion/removal for these batteries, which may create a condition for the cell to short circuit and nobody wants that. Please note this list is only a general guide - your charger may be different due to variations in manufacturing and cells within the same size are not the same and may not fit due to variations. There are no guarantees of damage before, during, and after using/charging them.

When it comes to batteries and your safety there isn’t such a thing as too safe. Your batteries are safe as long as you make them safe; carry them in a case, don’t exceed your battery capacity and always make sure the wrap is intact and the insulator is not damaged.
