FAQ

Q: What does 5A-10A Continuous Discharge Rating (CDR) mean?
A: It means the battery can safely and steadily output 5 to 10 amps. Compared to 30A cells, this battery prioritizes runtime and heat control, making it perfect for standard lighting.

Q: Can I use this battery for a TV remote?
A: No. Standard remotes use AA or AAA batteries. A 18650 cell is physically larger and supplies too much current, which could damage a remote.

Q: What’s the difference between Flat Top and Button Top?
A: Flat Top batteries have a flat positive terminal, suitable for spring-loaded devices (most flashlights and holders). Button Tops are for older devices. This item is Flat Top.

Q: Can I replace my flashlight's original battery with this?
A: If your flashlight uses 18650 batteries, generally yes. However, if your flashlight requires a high-drain cell (>15A), the 26E may produce dimmer light due to insufficient current.

Q: Do I need a protected circuit for this battery?
A: It's highly recommended to use this cell in devices with built-in protection circuits (over-charge/over-discharge). Never short-circuit or over-discharge a bare cell.
