APR 03, 2023   Pageview:323

Lithium-ion batteries are among the best current technologies for rechargeable batteries since the power-to-weight and mass ratios are quite amazing. These batteries make the right option for many options, including laptop batteries, power bank, and EV batteries.

However, we cannot charge these inside something every time, and that’s what the external 18650 chargers are made for. Read on and learn about the best chargers for your 18650 batteries.

Best-rated Battery Charger for 18650

Whether you go online or shop offline, you will find multiple chargers and multi-chargers dedicated to this battery type. However, before you buy one of these, make sure to have the following features as these features make the charger a better-rated one:

Fast Charging Speed

The first feature is fast charging speed. These batteries have a high charging capacity; normal chargers can take hours to charge. However, these batteries can be charged in a few minutes with the latest fast chargers, just like the latest smartphones. So, getting fast charging is a must since you cannot wait 5 hours or more to charge one battery. Consider having more batteries and one charger; the process will become so long.

Battery and Charger Protection Features

Fast charging is not the only feature you need, as you need to go for a charger that comes with all other standard features. These batteries are prone to catching fire when mistreated, and mistreating usually includes overcharging, over-voltage, over-current, etc. So, always go for a charger with the following charging protection features.

Overcharging protection

High-temperature charging protection

Over-voltage and current draw protection 

3.2V 20Ah Low Temperature Square LiFePO4 Battery Cell
3.2V 20A Low Temp LiFePO4 Battery Cell -40℃ 3C discharge capacity≥70% Charging temperature:-20~45℃ Discharging temperature: -40~+55℃ pass acupuncture test -40℃ maximum discharge rate:3C

Compatibility

You may need to look for compatible chargers offered according to your requirements. Some users only need these chargers for their 18650 batteries, while others want more features, including multiple battery compatibility, etc. So, depending on your requirements, you can select a charger that either supports the 18650 batteries only or supports multiple battery types and sizes, including your 18650 one. 

Smart Charging Features

The last thing to check is smart charging. These features are only compatible with smart battery systems with a battery management unit. So, if your battery comes with that, look for a charger with smart features.

Best 18650 Battery Charger Analyzers

A battery charging analyzer is a modern battery charge tester device that not only tests the charging state of your battery but provides a lot of other data about it. If you want the 18650 charging safety and experience to the next level, you can get a charger analyzer and better charging optimization for all your batteries. The most important things to look for in your battery charger 18650 analyzer include the following:

High Voltage Accuracy

The first one is high voltage accuracy. When dealing with a 18650 battery, you don’t want to get wrong with the voltage since their safe operating voltage range is very short. These batteries only charge and discharge between a few voltage points, and going beyond that is neither safe for you nor the battery. So, the analyzer must have high voltage accuracy.

Health and Charging Statics Determination

A good 18650 charging analyzer must come with charging performance statics information. You must know the battery health clearly and the overall charging condition of your battery as it helps determine the performance and life you can obtain from that battery. It is crucial to determine how reliable your battery is during different usage conditions.

Low Temperature High Energy Density Rugged Laptop Polymer Battery Battery specification: 11.1V 7800mAh -40℃ 0.2C discharge capacity ≥80% Dustproof, resistance to dropping, anti - corrosion, anti - electromagnetic interference

Accurate Current Draw Analyzation

The current and voltage draw for 18650 batteries vary depending on the application. For example, the power is stable and low when these batteries power a laptop. However, the power is high while life is less when using the same battery in a vape. So, the analyzer must be accurate with the current draw analyzation. It quickly helps in determining any issue in the system.

Smart Battery Management System Compatibility

For the best experience, you can get an analyzer that works as a charger. It may come with compatibility with a Smart battery management system that helps you determine complete charging statistics. Such products also offer you control over charging to maintain the health of your battery.

Best 18650 Battery Chargers for Vaping

While there are multiple applications and uses of these batteries, vaping is a unique one among all. These batteries have to output high power for smaller periods, but these periods are repetitive and continue for a long time. So, the batteries run out of juice quickly due to high power utilization, and charging them correctly matters a lot.

Charging Inside the Vape With Built-in Protection

In the old days, vapes were not equipped with the right technology, which severely affected the life and performance of batteries. However, things are much different today. Most high-quality vapes these days come with built-in charging circuitry that offers features like:

Overcharge and discharge protection

Fast charging

Optimized health, etc.

So, if you have the latest vape equipped with good technology, it will be the best charger for your battery.

Important: Remember not to vape and charge the battery simultaneously.

Charging Display

Chargers usually do not provide a display with any statistics about battery charging. They have a light that changes color once the battery is fully charged. However, when charging your vape’s battery with an external charger, a simple display will help a lot. You will know the exact charge percentage of your battery. So, you can even save your charge cycles.

High-temperature Prevention 

Heat is among the biggest enemies of the safety of a vape’s battery. If you have a charger that heats the battery to extreme temperatures, you cannot use it before it cools down, or there will be a high risk of explosion. So, get a charger that prevents heat and does not heat the battery or pause charging if the battery heats too much.

Conclusion

18650 batteries serve many applications since they can provide good power output for a long time and output bursts of power reliably. For some applications, we need to externally charge these batteries as individuals or as a battery pack. So, knowing what to look for when buying a charger for your battery is essential. Today, multiple smart options are available that help you charge the battery and track its charging statistics for safer and more efficient charging.
