Samsung 25R

20A High Drain, Flat Top 18650

One of the most well-known batteries on the 18650 market, the Samsung INR18650-25R has earned its reputation for a good reason. For a reliable and high-quality 18650 battery, you can't go wrong with Samsung.

The 25R hits that sweet spot with a 2,500mAh energy capacity and a 20A continuous high-discharge rating, making it an ideal choice for OEM battery packs in high-drain devices.

Li-ion INR Chemistry

Utilizing advanced LiNiMnCoO2 (INR) li-ion chemistry, the INR18650-25R's secret is a blend of manganese and nickel for extra energy while remaining stable and safe. These kinds of batteries keep a low internal resistance (≤m18Ω), while retaining high energy capacity, continuous discharge rates, and a low operating temperature.

Note that batteries are sold individually.

Rechargeable & Reusable

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

High Discharge Rate

20A 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

» 2,500mAh capacity offers long-lasting runtimes for all your devices

They had my battery
November 15, 2022
I looked all over the internet trying to find an obsolete battery and finally found it Battery Junction. It took no time to receive the battery as they stated when I placed my order. Soldiered metal tabs onto the new purchase and reassembled and worked and charged perfectly. Thanks!

A standard for a reason

There is good reason for this battery being suggested as a "go to" for high power flashlights. It flat out preforms well. As a new purchase time will tell for the long run but even that has a solid record

Almost what I ordered
February 28, 2022
While these did much better than a previous purchase from another vendor of cells that were supposed to be 9000 mAh (silly me!), they are not 2500 mAh as advertised. I tested each of the dozen I ordered, and they came in at 2253 to 2313 mAh, with an average of 2282 for the batch.
