Samsung 40T

High 35A Continuous Discharge Rate

The Samsung 40T is a 21700 battery that offers both a 35A max continuous discharge rate, and a large 4,000mAh capacity for extensive runtimes. That discharge rate can be further pushed to 45A for short-term (pulse) power.

As this is an unprotected cell with flat top terminals, the 40T is ideal in battery packs made for use in high-drain electronics.

Rechargeable & Reusable

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

High Discharge Rate

35A 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

» 4,000mAh capacity provides 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.

High performance flashlights friend

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

The correct battery for this light. Get them when they are cheap, they seem to fluctuate a lot.

Received this items faster than expected.

Also, in being transparent, I ordered these by mistake. I had meant to order the 18650's but messed up my search and ordered these instead. 100% my error.

And I am glad I did, these will actually fit my need better than the lower capacity 18650's. I have actually placed an order for the original 18650 so that I can build the original battery for use in another application.
