Description
Get extended runtime and dependable power with this 2-pack of 18650 3200mAh 9.6A flat top batteries. These 3.7V lithium-ion cells are built to bridge the gap between high capacity and mid-range discharge, making them an ideal energy source for headlamps, everyday LED flashlights, and a wide array of long-lasting devices. With a generous 3200mAh capacity, your gear runs longer between charges, while the 9.6A continuous discharge easily handles the current demands of medium-to-high brightness modes without voltage sag. The flat top positive terminal ensures compatibility with multi-cell packs, battery carriers, and flat-contact electronics. As unprotected cells, they require responsible handling: always pair with a dedicated Li-ion smart charger and only use in devices that have built-in over-discharge protection (or add an external protection board). Whether you’re heading into the woods with a headlamp, powering a portable fan through a workday, or keeping solar garden lights bright all night, these batteries deliver consistent, cost-effective energy cycle after cycle.
Key Features
-
3200mAh High Capacity – Longer runtime for headlamps, flashlights, and portable devices. Reduces the need for frequent recharges during extended outdoor use or work shifts.
-
9.6A Continuous Discharge – True 9.6A output with minimal sag. Powers LED flashlights on medium/high, strong headlamps, and small electronics without tripping over-current protection.
-
Flat Top Design – Standard flat positive terminal fits battery packs, multi-cell sleds, and most headlamps/flashlights with flat contacts. Check your device: some single-cell lights require button tops.
-
Rechargeable & Economical – Over 500 charge/discharge cycles, replacing hundreds of single-use alkaline or primary lithium cells. Zero memory effect means you can top up anytime.
-
Unprotected Cell – For Safe Use – These bare cells do not include a protection circuit board (PCB). You must use a Li-ion smart charger and ensure the device has low-voltage cut-off (2.5V). Never over-discharge, short-circuit, or charge without supervision.
-
Standard 18650 Form Factor – Dimensions 18.3 mm x 65.0 mm. Weighs approximately 47 g per cell, fitting almost any device designed for 18650.
Parameters
Applications
-
LED Headlamps – Ideal for caving, running, night fishing, or industrial headlamps that require steady, bright light for hours. 3200mAh capacity keeps the beam strong until dawn.
-
LED Flashlights – Perfect for EDC torches, tactical lights, and camping lanterns with moderate to high lumen output (single LED or multi-LED without extreme turbo). 9.6A ensures consistent brightness on high mode.
-
Desk & Portable Fans – Runs personal fans smoothly for extended periods. A single charge can power a small fan for 3-5 hours at medium speed.
-
Solar Garden Lights – Direct replacement for worn-out batteries in pathway lights, decorative solar lamps, and motion-sensor outdoor lights. 3200mAh stores enough energy for an entire night.
-
Wireless Electronics – Suitable for DIY Bluetooth speakers, wireless keyboards, or IoT sensor nodes that benefit from long battery life.
-
Multimeters & Test Instruments – Low-drain devices where a 3200mAh cell can last for months or even a year without swapping.
-
RC Toys (Low-Drain) – Powers small RC cars, robotic kits, and educational electronics projects.
FAQ
-
Q: What does 9.6A continuous discharge mean for my flashlight?
A: It means this battery can safely deliver up to 9.6 amps continuously. For most single-LED flashlights, high mode draws about 2-5A. This battery will handle that easily without dimming or voltage drop. It is not intended for turbo mode on high-power multi-LED lights that draw 15A or more.
-
Q: Are these batteries protected?
A: No. They are unprotected flat top cells. You must use a smart Li-ion charger and a device that has low-voltage protection (cut-off at 2.5V). Over-discharging below 2.5V can permanently damage the cell and create a safety risk.
-
Q: Can I use them in devices that require button top batteries?
A: Flat tops may not make contact in some flashlights with mechanical reverse-polarity protection that requires a longer button top. Check your device’s manual. Use only non-conductive magnetic spacers with extreme caution to avoid short circuits.
-
Q: How long will a 3200mAh battery last in a headlamp?
A: It depends on the brightness setting. For example, a headlamp drawing 1A on medium will run for about 3.2 hours. On low mode (0.3A), it could last over 10 hours. Actual runtime varies by device efficiency.
-
Q: What charger should I use?
A: Use a dedicated Li-ion smart charger for 3.7V 18650 cells (e.g., Nitecore, XTAR). Never use NiMH/NiCd chargers, and never leave charging unattended.
-
Q: How should I store these batteries?
A: Store at approximately 3.7V in a cool, dry place. Recharge every 6 months. Always keep in non-conductive cases—never loose in pockets with coins or keys.
