Battery Chargers

           I know for a fact that I've talked about battery safety and batteries here already, but like always little attention ever seems to get devoted to battery charges. Battery chargers can in some cases mean the difference between a freshly charged stable battery, and an overcharged battery that could go into thermal runaway.
           Cheap Chinese no name chargers are something to avoid like the plague, some of these chargers have no cut off voltage for charging, and rely on the battery having some kind of over charge protection built in. For vapers using IMR batteries this is a major problem, as IMR batteries have no overcharge protection. This means that you will likely end up needing a good quality charger that has a charge cut off of 4.2V. This might cost a bit more than a cheap Chinese piece of crap but in the long run, the battery charger will last longer and you wont chance over discharging your batteries.
            In order to practice proper battery safety all vapers should own a digital multimeter not only for checking atomizer resistance, but also for checking battery voltage before and after using a battery in a mechanical mod to check for over discharge and for over charging. However if you do not own a multimeter and use a 510 threaded ohm meter or have a mod that reads resistance, there are a few battery chargers on the marked that read the voltage of the battery when from the time you first put it on the charger until it is done charging. These kind of chargers are often not too much more than standard chargers.
           Currently I am using on of the Nitecore D4 chargers, and I have to say it is a solid unit that does it's job, and does it very well. Although the charge time is slightly below what I would say is fast, I know that the battery will be charged properly. If you are using a mechanical mod and do not have a digital multimeter I would highly suggest picking one up.
