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, high-quality, and safe battery, you can't go wrong with Samsung.

The 25R hits that sweet spot with a 2,500mAh energy capacity and a 20A high-discharge rating, making it an ideal choice for high-drain devices that need 'pulse' current rates.

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 low temperatures at the same time.

Just what I was looking for.

FIRST TIME BUYER: GREAT SERVICE, GREAT PRODUCT
January 6, 2021
This was my first purchase with Battery Junction. Everything was great. Great service, quick delivery, great product.
I have been buying the 18650 batteries through Amazon and at first was able to get a "genuine" Samsung battery. Since over a year ago I could not find a genuine Samsung so I was buying from other vendors. The batteries were very inferior to the Samsung brand.
I decided to order from Battery Junction and found the exact Samsung battery I needed.
I received these batteries at a great price and they seem to be working great. Long battery life and able to fully recharge these batteries.
I now will be looking to order batteries for my S5 phones and also expect great quality.
Hope to be a long time customer.

Great Batteries!
January 6, 2021
Purchased 3 of these batteries to replace my robo-vacuum battery pack, very easy to do. Lasts twice as long as the original batteries, highly recommend and will be ordering more for my other robo-vacuums.

I replaced the batteries in my automatic security lights, and they work like new now. Service was excellent at a great price. I would recommend them to anyone, and I will deal with them again.
