Description
Achieve the ideal balance of extended runtime and dependable power with the Vapcell T8, a high-capacity 16340 rechargeable cell delivering a full 950mAh with a stable 3A continuous discharge. This 4-pack is the perfect power solution for high-output tactical flashlights, digital cameras, night vision equipment, laser range finders, and security sensors. With approximately 20–35% more capacity than standard 700–800mAh 16340 cells, it provides significantly longer runtime between charges while still supplying ample current for demanding medium-high modes. The button top design ensures solid contact in all compatible devices. Critical Voltage Warning: This is a 3.7V lithium-ion rechargeable cell; standard disposable CR123A batteries are 3.0V. Using this battery in devices not designed for 3.7V can cause permanent damage. Always verify your device explicitly supports 3.7V 16340 (RCR123A) rechargeable cells before use. With Vapcell's trusted quality and excellent cycle life, the T8 keeps your essential gear running longer between charges—without the waste of single-use batteries.
Key Features
-
950mAh High Capacity – Among the highest capacities available in the 16340 form factor. Delivers approximately 20–35% more runtime than standard 700–800mAh 16340 cells, making it ideal for devices where extended operation is critical.
-
3A Continuous Discharge (CDR) – Provides stable, reliable power for high-output tactical flashlights, cameras, and electronic optics. Sufficient for medium-high modes on most compatible 16340 devices.
-
Button Top Design – Features a raised positive terminal for reliable electrical contact in flashlights, cameras, and devices requiring a button top for proper connection or reverse-polarity protection.
-
CR123A-Compatible Size – Physically identical in dimensions to a standard CR123A battery (approximately 16mm x 34mm). Fits all devices designed for the CR123A form factor. Voltage differs: 3.7V vs. 3.0V CR123A. Verify device compatibility before use.
-
Rechargeable & Economical – Eliminates the ongoing cost and waste of single-use CR123A batteries. One T8 can replace hundreds of disposable cells over its lifetime, paying for itself many times over.
-
Long Cycle Life – Retains over 80% of initial capacity after 500 charge/discharge cycles under recommended conditions, reducing long-term replacement costs.
-
4-Pack Convenience – Perfect for powering a tactical flashlight and keeping spares, or for devices that require multiple CR123A-sized cells.
Parameters
Applications
Recommended For
-
High-Output Tactical Flashlights (3.7V 16340 Compatible): Enjoy the cost savings of rechargeable power with excellent runtime. The 950mAh capacity provides extended illumination, and the 3A CDR handles medium-high modes with ease. Always verify your flashlight explicitly supports 3.7V 16340 cells.
-
Digital Cameras (Select Models): Some older digital cameras that accept CR123A batteries can use 16340 cells for improved performance and cost savings. Verify voltage compatibility in your camera's manual.
-
Night Vision Equipment & Thermal Optics: Professional and consumer night vision devices often use CR123A-sized cells. Rechargeable 16340s provide reliable, cost-effective power with extended runtime.
-
Laser Range Finders & Ballistic Calculators: High-drain optics benefit from the stable voltage and rechargeable convenience of the T8. The 950mAh capacity ensures you stay powered through long sessions.
-
Security Sensors & Alarm Systems: Certain systems use CR123A-sized backup batteries. The T8 provides longer standby time than lower-capacity alternatives. Verify 3.7V compatibility before installation.
-
Portable Medical Devices (Select Models): Compact diagnostic tools that require reliable power in a CR123A form factor.
Not Recommended For
-
Devices Designed Only for 3.0V CR123A: The T8 outputs 3.7V, which is significantly higher than the 3.0V of a standard disposable CR123A. Using this cell in devices not designed for 3.7V can permanently damage sensitive electronics. Always check your device's specifications.
-
High-Drain Devices (>3A Continuous): For FET-driven turbo flashlights or other applications requiring sustained high current above 3A, use a dedicated high-drain 16340 like the Vapcell T6 (650mAh/6A) or a larger form factor cell.
-
Devices with Extremely Tight Battery Compartments: While the T8 matches CR123A dimensions, some devices have extremely tight tolerances. The button top may add a slight increase in overall length compared to flat top disposable cells.
FAQ
Q: Can I use this battery to replace a standard CR123A in my flashlight?
A: Only if your device explicitly supports 3.7V rechargeable batteries. Standard CR123A batteries are 3.0V, while the T8 is 3.7V. Many modern tactical flashlights are designed to accept both voltages, but many older or simpler devices are not. Using a 3.7V cell in a 3.0V-only device can damage the driver or LED. Always check your device's manual or manufacturer specifications before use.
Q: How does the 950mAh capacity compare to disposable CR123A batteries?
A: A standard disposable CR123A typically has a capacity of about 1400–1550mAh at 3.0V. The T8 offers 950mAh at 3.7V, which provides comparable total energy (approximately 3.5Wh for the T8 vs. 4.2–4.6Wh for a disposable CR123A). The key advantage is that the T8 can be recharged hundreds of times, eliminating the ongoing cost and waste of disposable batteries.
Q: What is the difference between the T8 and the T6? Which should I choose?
A: The T8 is optimized for maximum capacity (950mAh/3A)—ideal for devices where runtime is the priority. The T6 is optimized for maximum current (650mAh/6A)—ideal for FET-driven turbo flashlights and high-power lasers. Choose the T8 if your device draws 3A or less and you want the longest runtime. Choose the T6 if your device needs high current bursts above 3A.
Q: Is the T8 different from the T9?
A: The T8 and T9 are essentially the same high-capacity cell (950mAh/3A) from Vapcell's 16340 lineup. The model numbers may reflect different batch runs or packaging variations, but performance, capacity, and specifications are identical. Both are excellent choices for maximum runtime.
Q: Can I charge this battery with any lithium-ion charger?
A: Yes. The T8 uses standard lithium-ion charging (CC-CV to 4.2V). It is compatible with most quality lithium-ion chargers that accept 16340-sized cells. Charge at 0.5C (475mA) 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.
