Description
Power your rare-sized devices with the Vapcell F11, a 14430 cell that delivers an impressive 1150mAh capacity and a steady 3A continuous discharge. This 2-pack is the ideal replacement for specialty compact flashlights, micro precision tools, high-power laser pointers, and portable medical devices that require the uncommon 14430 form factor. At approximately 43mm long, it is significantly shorter than a 14500 (AA) cell, fitting only in devices specifically designed for this size. Critical: The 14430 is a rare battery size—always verify your device's exact battery compartment dimensions before ordering. This is a 3.7V lithium-ion cell and must never be used in devices designed for 1.5V AA or AAA batteries. With Vapcell's trusted quality, the F11 keeps your hard-to-find-size equipment running reliably.
Key Features
-
1150mAh High Capacity – Among the highest capacities available in the rare 14430 form factor. Provides solid runtime for demanding compact devices without frequent recharging.
-
3A Continuous Discharge (CDR) – Stable, reliable power for high-output compact flashlights, laser diodes, and micro motor tools. Sufficient for bright modes on most compatible devices.
-
Flat Top Design – Compatible with devices featuring spring-loaded contacts. The flat positive terminal ensures reliable electrical connection.
-
Rare 14430 Form Factor – Diameter of 14mm (same as AA/14500) but only approximately 43mm long—about 7mm shorter than a standard 14500 cell. Designed exclusively for devices with this specific battery size. Always measure your device's battery compartment before ordering.
-
3.7V Lithium-Ion Chemistry – Standard nominal voltage for rechargeable Li-ion cells. Not compatible with 1.5V AA or AAA devices.
-
Long Cycle Life – Retains over 80% of initial capacity after 500 charge/discharge cycles under recommended conditions.
-
2-Pack Convenience – Perfect for powering a compact flashlight and keeping a spare, or for devices that require two cells.
Parameters
Applications
Recommended For
-
Compact Specialty Flashlights (14430 Compatible): Certain ultra-compact EDC lights are designed exclusively for the 14430 size. The 1150mAh capacity provides excellent runtime in a very short form factor. Must verify your flashlight uses 14430 cells before ordering.
-
Micro Precision Tools & Electric Screwdrivers: Some miniature power tools require the specific 14430 length for proper fit. The 3A CDR provides sufficient torque for precision applications.
-
High-Power Laser Pointers: Certain laser hosts are built for 14430 cells, providing the ideal balance of voltage and capacity in a compact size.
-
Portable Medical Devices (Select Models): Specialized compact equipment designed around the 14430 form factor.
-
IoT Sensors & Specialty Electronics: Devices that require this specific uncommon battery size for long-term deployment.
Not Recommended For
-
14500 (AA-sized) Devices: The 14430 is approximately 7mm shorter than a standard 14500 cell. It will not make proper contact in devices designed for longer cells. Always verify your device's exact battery size requirements.
-
18650 or 21700 Devices: The 14430 is significantly smaller in diameter and length.
-
Standard 1.5V AA or AAA Devices: This is a 3.7V lithium-ion cell and will permanently damage devices designed only for 1.5V batteries.
-
Devices Requiring Button Top Cells: This is a flat top cell. If your device needs a raised positive terminal, this cell may not make proper contact.
FAQ
Q: What is a 14430 battery? I've never heard of this size before.
A: The 14430 is a rare lithium-ion cell size—14mm in diameter (same as a AA/14500) but only 43mm long (7mm shorter than a 14500). It is used in a small number of specialty compact devices. If your device came with a 14430 cell or your manual specifies this size, the Vapcell F11 is one of the best replacements available.
Q: Will this battery fit my 14500 or AA flashlight?
A: No. The F11 is only 43mm long, while a 14500 (or standard AA) is approximately 50mm. The 7mm difference means it will likely not make proper contact, and your device will not work. Only use this cell in devices explicitly designed for 14430 batteries.
Q: How does the F11 compare to a 14500 cell?
A: The F11 is essentially a shorter version of a 14500. It offers 1150mAh capacity (compared to 1000–1250mAh for high-quality 14500s) and the same 3.7V voltage and 3A CDR. The only difference is the physical length—43mm vs. 50mm—making it suitable only for devices with shorter battery compartments.
Q: Can I use this battery in my standard AA device?
A: No. This is a 3.7V lithium-ion cell, which is more than double the voltage of a standard 1.5V AA battery. Using it in an AA device will destroy the electronics instantly. Additionally, it is shorter than an AA cell and will not fit properly.
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.
Q: Can I charge this with a standard lithium-ion charger?
A: Yes. The F11 uses standard lithium-ion charging (CC-CV to 4.2V). It is compatible with most quality lithium-ion chargers that can accommodate cells of approximately 43mm in length. Charge at 0.5C (575mA) for best longevity.
