Part 2: 18350 Battery Dimensions
The 18350 battery is defined by its dimensions: 18mm in diameter and 35mm in length. The “0” at the end of the name indicates its cylindrical shape. This compact size makes the 18350 a go-to choice for devices that require high power output but have limited space.
Compared to the 18650, which is often used in similar devices, the 18350 is shorter and lighter. This is why manufacturers often prioritize 18350 batteries when developing handheld or pocket-sized devices.
Part 3: Types of 18350 Batteries
18350 batteries come in several different types, each based on its chemical composition. Each type has unique characteristics that affect its performance in different applications.
- Lithium-Ion (Li-ion): The most popular type of 18350 battery, known for its high capacity and rechargeability. It delivers a stable power output, making it suitable for high-drain devices.
- Lithium Iron Phosphate (LiFePO4): This type is known for its excellent stability and long lifespan, making it one of the safest options. However, it typically offers a lower capacity compared to lithium-ion batteries.
- Lithium Manganese Oxide (IMR): IMR batteries are commonly used in high-drain devices like vape mods and flashlights. IMR batteries are popular for their stable chemistry and high discharge rates, though their lifespan may be relatively shorter.
- Protected vs. Unprotected Batteries: Some 18350 batteries come with a protection circuit that prevents overcharging, overheating, and short-circuiting. These are known as “protected” batteries and are generally safer for typical use. On the other hand, “unprotected” batteries lack this safety feature but are often used in high-drain devices where maximum power output is needed.
Choosing the right type of 18350 battery depends on your device’s power requirements, as well as your personal preferences for safety and performance.
Part 4: Are 18350 Li-Ion Batteries the Best Option?
Lithium-ion 18350 batteries are widely considered a top choice among the numerous options available. Their high capacity and rechargeability make them ideal for portable devices requiring reliable performance.

Part 5. 18350 Battery Capacity and Price
18350 batteries typically have a capacity ranging from 700mAh to 1200mAh, depending on the brand and type. While this capacity is lower than larger batteries like the 18650, it is often sufficient for compact devices for which the 18350 is designed.
Price Range: On average, 18350 batteries can range in price from $5 to $15 USD. The cost varies depending on the brand, type, and whether the battery includes built-in protection. High-end batteries, especially those with added safety features, tend to be more expensive. However, these batteries are often worth the investment for greater peace of mind and longevity.
Part 6. Are 18350 Batteries Rechargeable?
Yes, most 18350 batteries are rechargeable, making them a convenient and economical choice in the long run. Rechargeable batteries reduce the need for frequent replacements, which also makes them more environmentally friendly, especially for devices that are used frequently.
While there are some disposable 18350 batteries available, they are relatively rare. Rechargeable 18350 batteries are widely available and more suitable for high-drain devices.
Part 7. 18350 vs 18650 Batteries: What’s the Difference?
18350 and 18650 batteries share certain similarities, but there are significant differences between them:
- Size: The 18350 battery measures 18mm x 35mm, while the 18650 is larger at 18mm x 65mm. The larger size of the 18650 makes it a better option for devices that need extended battery life.
- Capacity: The 18650 offers a higher capacity, ranging from 1800mAh to over 3000mAh, while the 18350 has a smaller capacity. This translates to longer run times for the 18650, making it ideal for devices where battery life is a priority.
- Applications: The 18350 is often used in compact devices, while the 18650 is better suited for applications requiring long runtimes and high capacity.
