18350 Batteries

Reliable Power in a Compact Form

18350 lithium-ion batteries deliver high output in a short cell (approx. 18 mm × 35 mm), ideal for compact high-drain devices where space and weight matter. Typical nominal voltage is 3.6–3.7 V, with capacities commonly in the 700–1200 mAh range depending on brand and discharge rating.

High-Drain Performance

Favoured for LED torches, specialist instruments and other portable electronics, quality 18350 cells use modern Li‑ion chemistries (e.g. NMC/INR or LiCoO₂) to provide excellent energy density and stable discharge performance.

Compatibility & Sizing

Although similar in size to CR123A/16340 formats, 18350 is not the same cell and is usually not interchangeable unless your device explicitly supports it. Check the device manual for cell length, diameter, top style (button‑top vs flat‑top) and whether it requires protected or unprotected cells.

Charging & Safety

Rechargeable Li‑ion cells require a compatible Li‑ion charger. For best results, charge within the recommended voltage window, store partially charged when unused for long periods, and avoid mixing old and new cells.

FAQs
18350 cells are popular in compact, high‑output devices such as LED torches and specialist instruments where 18650 cells are too long.
No. While similar in size, they differ in length/diameter and intended use. Only use 18350 if your device specifies compatibility.
Yes. Use a dedicated Li‑ion charger that supports 18350 size and 3.6–3.7 V chemistry.
Follow the device manufacturer’s guidance. Protected cells add over‑charge/over‑discharge protection and are recommended for most general‑use devices.
Button‑top cells have a raised positive terminal and may be required for devices with series contacts; flat‑top cells sit lower and suit compact battery bays.
