18650 Rechargeable Batteries

Reliable Power for Your Modern Devices

The 18650 battery has become the gold standard for portable power. Roughly the size of an oversized AA battery, these rechargeable cells offer significantly more energy and a longer runtime than traditional alkaline options. Whether you are looking to revive a high-lumen torch or building a custom battery pack, we provide the reliable cells that keep your gear running through the toughest tasks.

Choosing the Right 18650 Battery

Not all batteries are created equal, and choosing the right one depends on how you plan to use it. Our selection covers the full spectrum of needs:

• Flat Top vs. Button Top: Many devices require a specific physical connection. Flashlights often use "button tops" (which look like a standard AA), while many battery packs and electronics require "flat tops" to fit snugly in their slots.
• Capacity (mAh): Measured in milliamp-hours, this tells you how much "gas" is in the tank. Higher mAh ratings mean longer runtimes between charges.
• High Drain vs. Standard: For devices that require a lot of power quickly, such as high-performance tools or torches, we carry "high drain" cells from trusted names like Samsung and Sony Murata.

Top Brands You Can Trust

We know that battery safety and quality are your top priorities. That is why we focus on carrying industry leaders known for their consistency and safety standards. Our inventory includes the latest technology from brands like Epoch, Samsung, and Sony. By offering a wide breadth of options, we ensure that whether you need a single replacement or a bulk order for a large project, you are getting genuine, high-performance cells.

Frequently Asked Questions

Are 18650 batteries the same as AA batteries?

No. While they share a similar cylinder shape, 18650 batteries are larger in both length and diameter. They also operate at a higher voltage (typically 3.6V to 3.7V) compared to the 1.5V of a standard AA. They are not interchangeable.

Do I need a special charger?

Yes. Because 18650s are lithium-ion batteries, they require a dedicated lithium-ion charger to ensure they are charged safely and efficiently. Standard NiMH or NiCd chargers will not work and could be dangerous.

What does "Protected" mean?

A "protected" battery features a tiny electronic circuit board built into the cell. This helps prevent the battery from over-charging, over-discharging, or overheating, providing an extra layer of safety for everyday use.
