1. What is 14500 battery?

The 14500 battery is a cylindrical rechargeable lithium battery. It gets its “14500” name from its dimensions which measure 14mm by 50mm. The 14500 battery typically has a nominal voltage of 3.2-3.7V.

Recent technological advancements have seen this battery achieve 600mAh to 1,000mAh which is impressive considering its size. They are capable of delivering decent amounts of power and ensuring that the devices they power run for longer durations before requiring a recharge.

2. What is 18650 battery?

The 18650 battery is yet another popular rechargeable lithium battery. It also gets its “18650” name from its dimensions - 18mm by a height of approximately 65mm. One notable thing about this battery that makes it so popular is its energy density.

With a nominal voltage of 3.2-3.7V, this battery’s capacity can range from about 1,500mAh to 3,000mAh. In fact, some major manufacturing companies have managed to increase their capacity up to 3,600mAh which is extremely impressive.

3. Comparison between 14500 battery vs 18650 battery - similarities and differences

14500 battery and the 18650 have lots of similarities as well as differences. Let’s take a look at the four most crucial aspects that define these batteries:

4. Application fields of 14500 battery vs 18650 battery

The 14500 and 18650 lithium-ion batteries can be used in several fields as follows:

5. Can I charge a lithium-ion 14500 battery or 18650 battery with a battery charger?

Yes, you can charge a lithium-ion 14500 battery as well as 18650 using a battery charger. And it is necessary to use a special charger for lithium-ion batteries, so as to best ensure charging safety and charging efficiency.

However, you’ll have to ensure that the battery charger is compatible with each specific battery. That means you’ll have to check the charger’s specifications and ensure that it supports Li-ion battery chemistry.

In addition, if charging a single cell, battery charger should support the 14500 or 18650 Li-ion battery size. Consider also checking the charger’s voltage and current ratings and ensuring that they match your battery’s charging requirements.

6. 14500 vs 18650: which is better?

Selecting between the 14500 battery vs 18650 is purely subjective - it depends on your unique needs. For example, if you are looking for a small rechargeable battery to power small devices, e.g., toys, small digital cameras, etc. the 14500 Li-ion is ideal for you.

On the other hand, if you are looking for a battery with larger capacity and higher energy density to power somewhat larger devices or want to pack a battery pack, consider going for the 18650 battery.

7. Are 14500 batteries the same as AA?

No. 14500 Li-ion batteries are not the same as AA batteries. You can easily confuse the two mainly because of their similar size. The AA of the AA battery only represents the size of the battery, and the type of battery is uncertain. And 14500 batteries are usually lithium-ion batteries.

AA batteries are typically not rechargeable - however, you can find rechargeable AA nimh batteries or even rechargeable AA lithium batteries in the market today. The AA battery is mainly used to power small electrical devices such as toys and digital cameras, which is similar to the field applications of the 14500 Li-ion battery.

AA batteries additionally have a lower nominal voltage of 1.5V while the 14500 battery has a nominal voltage of 3.2-3.7V and is rechargeable. So, it’s logical to conclude that while the 14500 Li-ion and the AA batteries have lots of similarities, they are totally different batteries.

8. What do you need to consider before buying a 14500 battery or a 18650 battery?

Choosing which battery to buy between the 14500 battery vs 18650 mainly depends on the amount of energy you need to efficiently power your devices.

● Power requirement

18650 battery carries a higher energy density compared to the 14500 battery.So, if you have electronic devices that require more power going for the 18650 battery will be a wiser option.

● Battery size

Another factor that you’ll definitely have to put into consideration is the battery’s size. Which size is your electronic device designed to use? Measure the available space designated for the batteries to know which battery size you’ll need to use.

● Battery capacity and voltage

Also, consider the battery’s capacity and voltage. Some devices have specific nominal voltages that they require, and you wouldn’t want to buy a battery and later on, find out that it cannot work well with your device.

In addition, checking the battery capacity will help you determine how long your battery will take before it requires a recharge after being fully charged. However, it is essential to note that batteries with higher capacities will run for longer durations but may be physically larger.

● Brand and quality

When considering which type of battery to buy between the 14500 battery vs 18650, one thing that is often overlooked and underrated is the brand and quality. Reliable brands that manufacture high-quality batteries often produce reliable and long-lasting batteries. Consider buying batteries from reputable brands.
