SparkFun Support and Front Desk will be closed on Thursday 11/14 from 1-2:30pm for a company event. Please plan to pick up your orders before or after this timeframe.
This is the same 18650 Lithium Ion Cell that you know and love, but now includes pre-attached solder tabs! These round high capacity cells have been mainly used in flashlight type applications but with its capability to be used as a drop-in rechargable cell at 3.7V with a capacity of 2600mAh. This battery has been made even better with the attached solder tabs. You now have a much wider range of applications to drop this battery into while still remaining simple to install!
These 18650 Cells have a standard discharge current of 0.2C to a maximum of 1C and can handle about 300 charge cycles.
Note: This battery is not available to ship to Alaska or Hawaii, or through any express services (2-day, overnight), or internationally. This is temporary! Check out our blog post for more information. Additionally orders may take longer to process and therefore do not qualify for same-day shipping. Sorry for any inconvenience this may cause!
Note: This item is non-returnable. If this item arrives damaged or is not functioning properly, please do not hesitate to contact us to see if further actions may be taken.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

I had previously purchased 18650 cells from eBay- the nameplate ratings said anything from 6AH to 4.2AH. The 6AH measured to be 800mAH and the 4.2 AH cells were 1.9AH. These off brand cells are never as good as their ratings. The SparkFun cells were spot on. Don't be fooled by sellers rewrapping cells. Very satisfied.

Quality construction and battery, good discharge curve. Tabs are weakly soldered and come off easily.
So like a lot of people I needed some 18650 cells for a project but I also dont want to solder straight onto a cell. Given that I lack a spot welder that seemed the only way to go.. but then I found these!
They act as my starter pack now before I actually need to handle decent current. Which is why we have 4/5 stars.
The discharge rate on these are fairly meh.
My wife found within her stuff a forgotten cylindrical USB power bank, featuring a dead Lithium rechargeable cell. It surprised me finding almost no such cells with solder tabs on the market. But I needed one because I can't spot-weld. Luckily there was this one. I could build it into my device, charge it from the computer's USB jack and charge an iPhone 5. The phone got full, and the power bank not empty. The left-over charge couldn't replenish the phone a 2nd time, so I have to be happy with the successful single run.
I got this to replace an old one in a cordless screwdriver and so far seems to have done the trick! I installed it and it worked better than the old one immediately, recharging it for the first time now. The solder tabs were a bit flimsy to insert in the connectors, but managed to get them in and secure.
I replaced the battery in a screwdriver with this item and now the screwdriver is up and running, so overall I'm happy. The solder tabs are so weak that I was convinced I was going to break them during assembling.
