18500 battery cells for compact 3.7V power
The 18500 battery format is a practical choice when you need a rechargeable lithium-ion cell that is shorter than an 18650 but still capable of delivering dependable energy. In this category you will find an 18500 Li-Ion 3.7V rechargeable battery designed for compatible devices, custom electronics, hobby projects, LED equipment and battery pack maintenance where this exact size is required.
The available KingKong LIR18500 model offers a nominal voltage of 3.7V and a capacity of 1500 mAh, making it suitable for users who want a balance between compact dimensions and useful runtime. Always check the technical requirements of your device before ordering, especially the required battery size, chemistry, voltage, polarity and discharge characteristics.
Why choose an 18500 lithium-ion battery?
An 18500 lithium-ion battery is typically used in applications where space is limited but rechargeable performance is important. The name refers to the approximate cell dimensions: 18 mm diameter and 50 mm length. This makes it different from other cylindrical Li-Ion formats such as 18350, 18490 or 18650, so correct identification is essential.
- Rechargeable Li-Ion chemistry for repeated use and lower waste compared with disposable cells.
- Nominal 3.7V output, a common voltage for many portable electronic applications.
- 1500 mAh capacity for reliable operating time in compatible devices.
- Compact 18500 size for equipment that cannot accept longer cells.
- Useful for replacements when your original LIR18500 cell has reached the end of its life.
Compatibility and safe use
Before using any LIR18500 rechargeable cell, confirm that your charger supports lithium-ion batteries and the 18500 format. Do not charge Li-Ion cells in chargers intended only for NiMH, NiCd or alkaline batteries. If the cell is intended for a battery pack, ensure the pack configuration, protection circuit and charging system are suitable for the exact voltage and chemistry.
For safe operation, avoid short circuits, excessive heat, mechanical damage, deep discharge and overcharging. Store batteries in a cool, dry place and transport them so that the terminals cannot touch metal objects. If a battery becomes swollen, overheated, damaged or shows unusual behaviour, stop using it immediately.
Tip: The 18500 size is not interchangeable with every similar-looking cylindrical battery. Measure your old cell or check your device manual before purchase.
