To Diagnose Problems with an Electronic Cigarette Battery, you have to determine if the battery is the only faulty component. You need to Disconnect and reconnect the battery and the filter. If another battery is available, you must use that to make sure that the filter is not faulty. After that, remove the battery from the filter. You should look at the area around the nicotine cartridge for any visible liquid on the filter or battery.
If the battery is wet, you can place it in a zip lock bag of rice for twenty four to forty eight hours to remove any moisture. Then, Insert the battery into the charger to ensure it is properly charged.
