18650 Battery Safety-Precautions, Protection and Performance

The 18650 is a type of lithium-ion rechargeable battery and has become gasoline today. The 18650 batteries have revolutionized mobile devices. They’re all in it, from smartphones and cameras to baby monitors, exercise devices, and flashlights. The 18650 battery comes up with better performance as it is user-friendly design, but it also has distinct disadvantages if not managed carefully. If you have a 18650 battery, you should always look for tips to use it for better battery performance and safety.

Here is a complete guide where we talk about 18650 safety precautions, protection, and performance.

What are 18650 battery safety precautions?

Not all batteries were made equally. 18650 batteries require the user to be focused and knowledgeable, but they are safe to use once you know how to use them. These are some of the precautions you should take when you use, handle, and store 18650 lithium-ion batteries.

The following are some of the suggestions for having the full life cycle of the 18650 lithium batteries.

1. Not to carry 18650 batteries in your pocket.

To prohibit the batteries from causing problems with other connections in your pocket, 18650 batteries must be carried in a carrying case which protects them from touching anything else. As this happens, the battery gets hotter and hotter until the "vents" of battery acid out of the battery transform into a "winded battery."

2. Do not use a damaged battery.

That one should be clear, but it is something that we still see in vaping as well as the source of most battery failures. Using or charging damage batteries may cause the cells to vent. Damaged batteries, too, will destroy your box mod, fry the chip and turn your vape into nothing more than a crispy weight of paper. If a battery 's old wrapping gets broken, put it back in the plastic carrying case and get it "rewrapped" with a new cover.

3. Match battery types together.

Always use the same kind of battery together to avoid a power imbalance between the different cells. For instance, if you have a dual-mode battery, a set of 18650 LG HE4 yellow batteries, and a 18650 Sony VTC6 battery, do not mix and match the Sony batteries with the LG batteries. Choose the same form, color, mAh rating, size, and condition batteries. When severely misused, the use of two or more separate batteries in multiple battery devices can cause damage or venting.

4. Do not leave charging batteries unattended.

Should not leave 18650 batteries unattended when charging. Although most chargers are made of fireproof material, there might be chances of electronics and fires happening. When finished, cells only take around 3 hours to charge on the slowest charging mode. Charging through the micro USB of the computer is not highly recommended.

5. Never store batteries with metal.

The battery terminals inside your vape are the only metal your batteries should be touched. When 18650 batteries are exposed to metal, this will create a circuit and consume energy continuously until they wind up.

When do you need a protected 18650 battery?

Protected Lithium-Ion ( Li-ion) batteries have a thin, integrated electronic circuit in the cell packaging. This circuit protects the battery from common hazards such as overload, overload, short circuit/overcurrent, and temperature. Protected batteries on your devices are safer to use. Safe batteries are less like igniting and cause harm to persons or properties.

Understanding the need for protected batteries:

• The protected batteries have a component PTC which defend against overheating, and indirectly against the current.  It reset automatically to protect the 18650 battery.

• A pressure valve which disables the cell permanently if the pressure is too high in the cell (Can be due to overcharge).
  

• It can protect against over-release, over-charge, and over-current, depending on nature. The PCB will be automatically reset when connected with a charger.

How is the performance of the 18650 battery?

The 18650 cell has the highest performance of any rechargeable battery in the user class. Until being completely discharged, they are not prone to harm from charging, but they can degrade at around the same rate as your smartphone battery.

Advantages of the 18650 lithium battery:

1) Large capacity

The 18650 lithium battery typically has a range varying from 1200mah to 3600mah, while the overall battery capacity is just around 800. The 18650 lithium battery pack will easily break through 5000mah if merged into a 18650 lithium battery pack.

2) Long life

The 18650 lithium battery has a long-lasting life. In regular usage, the cycle life can exceed more than 500 times, more than double that of ordinary batteries.

3) High-security performance

The 18650 battery has all types of safety output in one go. The High-temperature resistance is fine, Discharge efficiency under 65 degrees is up to 100 percent.  Both the poles of the 18650 lithium battery are isolated to prevent battery short circuit. A protective plate can be added to avoid overloading and over-discharging of the battery, which also increases the battery life.

4) The internal resistance is small:

The polymer battery core's internal resistance is lower than the general liquid batteries. The inner strength of the domestic polymer battery can be even less than 35 mm, drastically decreasing the battery's self-consumption and prolonging the cell phone's standby time. This polymer lithium battery is an excellent option for remote control models. It is the most potential solution to nickel-metal hydride batteries.

5) A wide range of uses

In recent years, 18,650 batteries have also commenced being applied to the new energy automotive industry, with the strong rise of new energy vehicles. Therefore, the automotive sector has joined the 18650 battery models R&D team. There will be more models that "fall in love" with the 18650 battery, causing a dramatic improvement.

The Final Verdict

The use of 18650 batteries has increased recently because of its better performance and the protection provided to the gadgets. The safety is also essential, and you must always be careful while using the 18650 battery.
