Tweeze Your Buttons

These super handy little tweezer-style battery testers are made for checking button-cell and 3V lithium coin-cell batteries. Red and black arms designate the +/- sides and an LED at the base lights up if the battery is good.

Jarvis Says: These are intended for use with a 3V Lithium Coin cell battery (i.e. CR2032 etc...). The LED lights very dimly with 1.5 Volt batteries and are therefore not recommended for that purpose, despite the claims of being able to do so on the product's packaging.
