2-Pack 18650 3200mAh 9.6A Flat Top Rechargeable Battery – 3.7V Li-ion for Headlamps, LED Flashlights & Long-Lasting Devices
Description
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.

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.

Security
Even at max draw from my flashlight, these stay cool. The 9.6A rating seems conservative¡ªthey handle slightly more with ease. My new go-to for long trips.
Bought these for my dive light. The flat top doesn't get dented by the spring. 3200mAh gives me enough time for two night dives. No leakage, no issues.
While not high-drain, the 9.6A is fine for my headlight and small fan. The 3200mAh capacity means all-day use. They feel like quality cells.
I use these in my automatic soap dispenser and it's been months without a recharge. 3200mAh is legitimate. Perfect for any device you don't want to charge often.
My shortwave radio sips power, but these high-capacity cells mean I can listen for days. The flat top works with the battery compartment. Tops off quickly.
