Power / Non-Rechargeable Batteries

These are the highest quality & capacity batteries, the same as shipped with the iCufflinks, iNecklace, Datalogging and GPS Shields, GPS HAT, etc. One battery per order (you'll want one battery per cufflink or pendant.) Brand may vary but all battery brands are verified to have the same nominal voltage of 3.0V and nominal capacity of 40mAh

Battery power for your portable project! These batteries are good quality at a good price, and work fantastic with any of the kits or projects in the shop that use AAA's. This is a pack of 2 AAA batteries. These batteries are Alkaline (MnO2) chemistry, with a voltage range of 1.6V (fresh) to 0.8V (dead). The mAh capacity depends on discharge usage but at 25mA rate it...

This is a handy little non-rechargeable CR2016 Lithium Coin Cell Battery! Sitting at 20mm diameter and is 1.6mm thick it's small but packs a punch with a nominal voltage output of 3V and a capacity of 90mAh. For other drain rates the capacity may be reduced, check the datasheet! Note that these are often "stacked" to make a 6V CR2032-sized pack of batteries.

Battery power for your portable project! These batteries are good quality at a good price, and work fantastic with any of the kits or projects in the shop that use AAs. This is a pack of 3 AA batteries. These batteries are Alkaline (MnO2) chemistry, with a voltage range of 1.6V (fresh) to 0.8V (dead). The mAh capacity depends on discharge usage but for AA alkaline...

A perfect match for our sew-able coin cell holder. This non-rechargeable coin cell is CR2032 sized: 20mm diameter, 3.2mm thick. It has a nominal voltage output of 3V (although it starts a little high at 3.2V and slowly drifts down to 2.5V as it is used. The capacity is 220mAh assuming a draw of constant .2mA. For other drain rates the capacity may be reduced, check...

Battery power for your portable project! These batteries are high quality at a good price and work fantastic with any of the kits or projects in the shop that use 9V. These batteries are Alkaline (MnO2) chemistry, with a voltage range of 9.6V (fresh) to 4.8V (dead). The mAh capacity depends on discharge usage but at 50mA rate it is about 500mAh (check the datasheet...
