Polymer Lithium Ion Battery - 110mAh (Solder Tabs)

This is a very small, extremely light weight battery based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 110mAh! Unlike our other 110mAh batteries, this model comes terminated with two small solder tabs for easy connection on your next low power project. These batteries require special charging so be sure to not attempt to charge these with anything but a specialized Lithium Polymer charger.

Make sure to note that, unlike our other 110mAh batteries, this little guy does NOT include built-in protection against over voltage, over current, and minimum voltage. Please use caution when using this battery in wearable projects. When using conductive thread, a short in the thread can create sparks and heat. We recommend using coin cell batteries for beginners.

Note: Due to the requirements of shipping these batteries, orders may take longer to process and therefore do not qualify for same-day shipping. Sorry for any inconvenience this may cause.


  • Excellent long-term self-discharge rates (<8% per month)
  • Robust power source under extreme conditions (-25 to 60C)
  • Datasheet (The datasheet is incorrect, these are not limited to a 2C discharge and the dimensions are wrong)
  • [MSDS](http://cdn.sparkfun.com/datasheets/Prototyping/Lithium Ion Battery MSDS.pdf)

Polymer Lithium Ion Battery - 110mAh (Solder Tabs) Product Help and Resources

Core Skill: Soldering

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.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
See all skill levels

Core Skill: Electrical Prototyping

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.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    If the dimensions in the datasheet are wrong, what are the correct dimensions?

  • Blueblast88 / about 9 years ago / 1

    Anyone know a good charger for this? I would love to buy a few of them but i need a charger before i do.

  • Chiel / about 9 years ago / 1

    If the discharge limitation of 2C is incorrect. Then what is the actual limitation? its kinda important considering there is no built-in protection. Also what are the real dimensions?

    Is this powerful enough to power a RasPi for three hours?

    • Chiel / about 9 years ago / 1

      Very unlikely. RasPi consumes up to 700ma@5v (Model B). You will probably want the 2000mah version if you want the raspberry to work for atleast 3 hours at maximum consumption. You may also want to look up on how others power the Raspberry pi of batteries. Some parts need 5v and others 3.3v so you may need to do some boosting and regulating to get everything working properly.
