Generally, lithium ion batteries are deemed safe because these disposable batteries lack the energy necessary to explode enough to cause damage. Even with its relatively low failure rate, there have been instances of batteries becoming so hot that melt in the process. In other instances users, like the man from Muskogee, use modded electronic cigarettes (custom electronic cigarette builds) which aren’t rigorously tested under factory specifications. The failure rate for these devices raise exponentially as the battery is more often than not pushed to its limits.

That being said, the failure rate of lithium ion batteries is slim to none. A potentially dangerous explosion of a lithium ion battery manufactured from an electronic cigarettes company is highly unlikely. To be safe, we recommend monitoring the heat being emitted from the device at all times. If the heat is apparent, it may be wise to stop using it and let the electronic cigarette cool down. If the problem continues, that’s a sure sign of future battery failure and should be replaced immediately. If the problem persists, it may be time to replace the electronic cigarette entirely.

Speaking of replacements, electronic cigarette batteries are designed to charge and recharge numerous times. However, a battery’s charge will continue to diminish over time resulting in less charge being retained. When that happens, it’s time to swap the low powered battery for a new one. Really, it all depends on your use. If you frequently charge and recharge your electronic cigarette, the battery may need to be replaced sooner. Battery longevity of most electronic cigarette brands last for at least a year with moderate use.

When the time comes to get rid of your battery, don’t throw it away in the trash. Lithium ion batteries have the potential to degrade over time resulting in potential contamination of soil and water. Instead, look for battery disposal friendly locations that allow batteries to be dropped off. Recycling lithium ion batteries is also a viable option. For batteries you continue to keep or don’t use, house them in plastic bags or containers away from one another as keeping them in close contact can lead to shorts or sparks.
