Description
Keep your specialty-sized devices running longer with the Vapcell 18500 2200mAh battery. This 10-pack delivers a solid 2200mAh capacity and a reliable 4A continuous discharge, making it an excellent power source for short-body flashlights, compact headlamps, portable fans, electric toothbrushes, and medical devices designed for the 18500 form factor. Available in flat top or button top options to match your device. At 50mm long—15mm shorter than an 18650—it fits perfectly where a full-size cell is too long, yet provides significantly more runtime than smaller 18350 alternatives. Important: The 18500 is a distinct battery size. Always verify your device explicitly requires an 18500 cell before ordering—it will not fit in 18650 or 18350 compartments. With Vapcell's trusted quality, long cycle life, and bulk-pack value, this 10-pack keeps all your hard-to-fit devices powered and ready.
Key Features
-
2200mAh High Capacity – Provides dependable, extended runtime for medium-drain devices. A meaningful upgrade over typical 1500–2000mAh 18500 cells. More energy means fewer battery swaps.
-
4A Continuous Discharge (CDR) – Stable, reliable power for regulated LED flashlights, headlamps, portable fans, electric toothbrushes, and similar everyday electronics. Sufficient for medium-high flashlight modes.
-
Flat Top & Button Top Options – Choose flat top for devices with spring-loaded contacts, or button top for devices requiring a raised positive terminal for proper connection or reverse-polarity protection.
-
18500 Form Factor – The Shorter Fit – Same diameter as an 18650 (18mm) but only 50mm long—15mm shorter. Designed exclusively for devices that need more capacity than an 18350 but cannot fit a full-size 18650. Always verify your device's battery compartment length before ordering.
-
INR Chemistry – Offers excellent energy density and low internal resistance, making these cells well-suited for everyday use in a wide range of portable electronics.
-
Long Cycle Life – Retains over 80% of initial capacity after 500 charge/discharge cycles under recommended conditions, reducing long-term replacement costs.
-
10-Pack Bulk Value – Perfect for stocking up, powering multiple specialty flashlights, keeping spares for the whole family's headlamps and fans, or equipping a fleet of compact devices.
Parameters
Applications
Recommended For
-
Specialty Short-Body Flashlights (18500 Compatible): Enjoy extended runtime in compact lights designed for 18500 cells. The 2200mAh capacity keeps your light shining through long walks, camping trips, or professional inspections.
-
Compact Headlamps: Lighter than 18650-powered models, yet with ample capacity for extended outdoor use. Ideal for runners, cavers, and DIY enthusiasts.
-
Portable Fans & Mini Cooling Devices: Certain compact fans accept 18500 cells. The 2200mAh capacity ensures longer cooling sessions on hot days.
-
Electric Toothbrushes (Select Models): Some rechargeable toothbrushes use 18500 cells. This 10-pack ensures the whole family always has a fresh battery ready.
-
Portable Medical Devices: Compact diagnostic tools, portable monitors, and infusion pumps that require reliable, long-lasting power in a shorter-than-18650 package.
-
Wireless Mice & Keyboards (Select Rechargeable Models): Low-power peripherals that benefit from the large capacity and long cycle life.
Not Recommended For
-
18650 or 18350 Devices: The 18500 is a distinct size—15mm shorter than an 18650 and 15mm longer than an 18350. It will not fit properly in compartments designed for other sizes. Always measure your device's battery tube or check the manufacturer's specifications.
-
Standard 1.5V AA Devices: This is an 18mm diameter, 3.7V cell. It is completely incompatible with AA devices in both voltage and physical size.
-
High-Drain Devices (>4A Continuous): For FET-driven turbo flashlights, high-power vaping, or motorized tools requiring 5A+, use a dedicated high-drain 18500 like the Vapcell 2000mAh (10A) or a larger form factor cell.
FAQ
Q: What is an 18500 battery? Will it fit my 18650 flashlight or 18350 device?
A: The 18500 has the same diameter as an 18650 (18mm) but is only 50mm long—15mm shorter than an 18650 and 15mm longer than an 18350. It is a distinct size and will only fit devices specifically designed for 18500 cells. Always check your device's manual or measure the battery compartment before ordering.
Q: What is the difference between flat top and button top? Which should I choose?
A: Flat top cells have a completely flat positive terminal, ideal for devices with spring-loaded contacts and for spot-welding custom packs. Button top cells have a raised positive nipple, required by some flashlights and devices for proper contact or reverse-polarity protection. Check your device's requirements before selecting.
Q: Can I use this battery in my AA-powered device?
A: No. This is an 18mm diameter, 3.7V lithium-ion cell. Standard AA devices use 14mm diameter, 1.5V cells. Both the voltage and physical size are incompatible, and using this cell will permanently damage the device.
Q: Can I charge this with any lithium-ion charger?
A: Yes. This cell uses standard lithium-ion charging (CC-CV to 4.2V). It is compatible with most quality chargers that accommodate 50mm-long cells. Charge at 0.5C (1100mA) for best longevity.
Q: How should I store these cells when not in use?
A: Store at 3.6–3.7V (approximately 40–50% charge) in a cool, dry place. Use non-conductive battery cases to prevent accidental short circuits. Avoid storing fully charged or deeply discharged for extended periods.
