How to take care of your new Joye 510 Electronic Cigarettes:   Here are a few tips regarding the maintenance of your new e-cigs, in case you never used them before and you are not familiar with how to take care of them.   1. Charge the battery.   When you get your kit, please fully charge the batteries. As you puff on the e-cigarette, please avoid holding down the button on the battery for longer the 5 seconds, although I doubt anyone can inhale for longer then 3 seconds. Make sure that wherever you are keeping them, nothing is going to press down on the little button. After the first charge, then it only takes about an hour to charge a battery.   2. Keep atomisers moist.   In order for the atomisers not to dried out, they come already "moist" and for the start they may not taste that great so after a few puffs, the liquid that was put on them from the factory will burn out and you will start tasting the e-liquid you will be using or the one from the new cartridges. Please make sure that the atomisers are moist at all times and they NEVER dry out as this will "kill" them. As you puff away, if at one point you feel the taste of the e-cigarette getting weak or it become tasteless, make sure you add more liquid or change the cartridge and that the battery is charged.   3. Keep your electronic cigarettes clean.   Once a month or so, you will want to clean your cigarette. Around the gold metal treads, where you screw the battery with the atomiser together, you will notice the bright gold that gets darker (dirty) and you might want to use a napkin or a soft cloth to clean both sides and then screw them back together. Gently though do the same with the inside of the atomisers.   4. Do not drop your e-cigarettes.   These are electronic devices and as with all electronics they must be taken care of, not being dropped on hard surfaces or in liquid.   The atomisers and the batteries are interchangeable. I have been using the same kit for 5 months. I must have saved at least $ 900 by now. so its really worth it to take good care of them. As a heavy smoker I only use a 10ml bottle of e-Juice (e-Liquid) per month. Of course, this varies depending on everyone's smoking habits.   I hope you will enjoy your new electronic cigarettes and hopefully these tips will help you.
