Power / Non-Rechargeable Batteries

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...

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.

This is a super beefy non-rechargeable CR2450 Lithium Coin Cell Battery! Coming in at a 24.5mm diameter and 5mm thickness this battery kicks major butt with a nominal voltage of 3V and a capactiy of 610mAh! For other drain rates the capacity may be reduced, check the datasheet!

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.

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...

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

These batteries are super popular in small electronic objects - and now you don't have to toss it out when the battery dies. This product comes with a ten pack of non-rechargeable LR44 button cell batteries. Each battery is 11.5mm diameter and 5.3mm thick. One battery has a nominal voltage output of 1.5V and a capacity of ‎120 mAh. Handy and adorable, but they...
