This is a coin cell holder for the common CR2032 type battery. The holder has a neat pop-in, pop-out feature that makes changing the battery easy. The feet of the holder have a small hole that allow it to be sewn without modification.
These are your standard 1.5V AAA alkaline batteries from Rayovac. Don’t even think about trying to recharge these. Roughly 750mAh per AAA cell. Combine 4 to get ~6V peak, and ~4.8V as they hit their discharge curve.
What sets this battery apart from our other 110mAh battery is that fact that it was truly made for e-textiles projects. With no risk to short out and a low current delivery, the E-Textiles Battery will cut off in the range of 240-380mA making this the safest option to power electronics sewn into pieces of fabric.
This is a simple coin cell battery holder that can enclose two CR2032 batteries inside itself, and safely kept closed via two phillips head screws. Each battery holder will run batteries in series, output up to 6V, and is equipped with an On/Off slide switch and two 6" power wires (one positive and one negative) on the back.
These are very slim, extremely light weight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 1000mAh! 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.
This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as on the LilyPad Slide Switch Board, so it’s not easy to accidentally turn off or on.
CR2032 Lithium metal 3V 250mAh button cell battery. Great for powering low power processors or blink an LED for weeks at a time.
