Polymer Lithium Ion Battery - 40mAh
PRT-13852 ROHS
DESCRIPTION FEATURES DOCUMENTS
This is an extremely tiny and 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 40mAh. This may sound like not so much
power, but the cell is really tiny… like, about half an inch square!
Comes terminated with a standard 2-pin JST-PH connector - 2mm spacing
between pins. These batteries require special charging. Do not attempt to
charge these with anything but a specialized Lithium Polymer charger. Battery
includes 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: 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.

I make my own design with the LTC4081 from Linear or the STNS01 from ST.

How can you charge one of these little 40mah lipos?

I guess there is a mistake in the Datasheet. The black wire is written as + and the red wire is written as -.

What can we use to charge these? I don’t see any charger boards in your catalog that do anything under
100mA…
