My battery won’t charge

If your battery is not charging it may be due to a number of different factors. Firstly, ensure that the charger you are using is the correct charger for the battery. Next, make sure that you are charging the battery the correct way. Some batteries are charged via the top connection (510 charger), others charged from the bottom via a micro USB. Mods that take external batteries require an external charger for the battery cells, although some also have a micro-usb port.
