Description
Keep your everyday compact devices powered without overspending with the Vapcell C8. This 14500 cell delivers a practical 800mAh capacity and a reliable 2A continuous discharge, making it the smart choice for 3.7V-compatible LED flashlights, headlamps, electric toothbrushes, wireless mice, remote controls, and small electronics. Available in flat top or button top options to match your device. Critical Warning: This is a 3.7V lithium-ion cell—physically identical in size to a standard AA battery but operating at more than double the voltage. Never use it in devices designed only for 1.5V AA batteries, as it will permanently damage the equipment. With Vapcell's trusted quality and a 10-pack bulk value, the C8 keeps all your compatible devices running reliably without the premium price.
Key Features
-
800mAh Practical Capacity – Provides dependable runtime for low-to-medium drain devices. An affordable entry point to genuine Vapcell 14500 cells, perfect for devices that are charged regularly and do not require maximum capacity.
-
2A Continuous Discharge (CDR) – Stable, reliable power for LED flashlights, electric toothbrushes, portable fans, and other small electronics. Sufficient for most everyday applications.
-
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 electrical connection.
-
Compact AA-Sized Form Factor – Same physical dimensions as a standard AA battery (14mm x 50mm), but operates at 3.7V nominal. Must only be used in devices explicitly designed for 3.7V 14500 lithium-ion cells.
-
Long Cycle Life – Retains over 80% of initial capacity after 400 charge/discharge cycles under recommended conditions, reducing long-term replacement costs.
-
10-Pack Bulk Value – Perfect for stocking up, powering multiple devices around the house, or keeping spares ready for the whole family's toothbrushes and flashlights.
Parameters
Applications
Recommended For
-
LED Flashlights & EDC Torches (3.7V 14500 Compatible): Enjoy brighter output compared to standard AA batteries in compact flashlights that explicitly support 3.7V 14500 cells. The 800mAh capacity covers daily short-to-medium use with ease.
-
Headlamps (3.7V 14500 Compatible): Lightweight, affordable power for camping, running, and DIY headlamps designed for 14500 lithium-ion cells.
-
Electric Toothbrushes (Select Models): Many popular rechargeable toothbrushes use 14500 cells. The 10-pack ensures you always have fresh batteries ready for the whole family.
-
Wireless Mice & Keyboards (Select Rechargeable Models): Low-power peripherals run for months on a single charge with these cells.
-
Remote Controls (Select Models Supporting 14500): Extremely low power draw—a single charge can last over a year.
-
Mini Portable Fans: Certain compact fans accept 14500 cells, and the 3.7V voltage provides stronger airflow than 1.5V AA alternatives.
-
Smart Doorbells & Small Electronics: Select models that use 14500 backup batteries benefit from the reliable, affordable power.
Not Recommended For
-
Standard 1.5V AA Devices: This is a 3.7V lithium-ion cell—using it in devices designed only for 1.5V AA batteries will permanently destroy the electronics. Always verify your device explicitly supports 3.7V 14500 lithium-ion cells before use.
-
High-Drain Devices (>2A): For hot-rod flashlights with FET turbo modes or power-hungry devices requiring 3A+, use a dedicated higher-drain cell like the Vapcell F15 (3A) or K10 (8A).
-
18650 or 21700 Devices: The 14500 format is physically smaller (14mm vs. 18mm/21mm) and will not make proper contact in larger battery compartments.
FAQ
Q: Is this battery the same size as a regular AA battery? Can I use it in my AA flashlight?
A: Yes, the C8 has the exact same physical dimensions as a standard AA battery (14mm x 50mm). However, it operates at 3.7V, which is more than double the voltage of a 1.5V AA alkaline battery. You must only use this cell in devices explicitly labeled as supporting 3.7V 14500 lithium-ion cells. Using it in a standard AA device will likely destroy the electronics instantly.
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 that can accommodate the slight recess. Button top cells have a raised positive nipple, required by some flashlights and devices for proper electrical contact or reverse-polarity protection. Check your device's battery compartment or manual for the correct type.
Q: Can I charge this with a standard AA charger?
A: No. You must use a lithium-ion charger designed for 3.7V 14500 cells. Standard NiMH or alkaline AA chargers will not charge this cell correctly and could create a safety hazard. Always use a charger with a CC-CV algorithm and proper voltage cutoff (4.2V).
Q: How does the C8 compare to other Vapcell 14500 cells like the L10 or F15?
A: The C8 offers 800mAh with a 2A CDR—the most affordable entry in Vapcell's 14500 lineup. The L10 provides 1050mAh/3A for a balanced mid-range option. The F15 provides 1500mAh/3A for maximum runtime. Choose the C8 if your devices have modest capacity needs and you want the best value for everyday use.
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.
