Samsung 20S

High 30A Continuous Discharge Rate

The Samsung 20S is a rechargeable 18650 battery that utilizes INR (lithium nickel manganese) chemistry. While its 2,000mAh capacity may be on the lowered end compared to other Samsung 18650 batteries, its incredibly high 30A max discharge rate makes it ideal for high-drain devices.

As this is an unprotected battery with flat top terminals, the 20S is recommended for use in making battery packs.

Rechargeable & Reusable

Invest in a rechargeable battery that will last for years to come– this battery can be recharged 250+ times.

High Discharge Rate

30A max continuous discharge rate for high-drain electronics, great for making battery packs for devices that require minimum discharge rates.

3 Year Shelf Life

Stock up and store spare batteries with confidence– lithium ion batteries have a 3+ year shelf life, ensuring you always have a fresh replacement when you need it.

Notable Features

» 2,000mAh capacity offers significantly long runtimes for all your devices
» Flat top terminal is perfect for use in making OEM battery packs
Please note that these batteries have flat top terminals, and may not be compatible with some devices.
Check with your device's user manual whether your device requires button top or flat top terminals.

Needed to replace defective battery in rechargeable LED flashlight. Found this replacement, getting two batteries for what I expected to pay for one. Works well. Happy with purchase.
