Introduction: Free Batteries in Try Me Buttons
I realize this isn't necessarily a how-to but I thought I'd share. If you're wondering why companies are so eager to have the customer throw out their try me buttons, a big reason could be the fact that the try me buttons are powered by LR44 batteries, aka, button-cell. These batteries go for about $5 for a pack of 3, so getting these batteries with something we were planning on buying in the first place is awesome!
The third button I got actually had a mini capsule attached to it. In that were 3 batteries.
In a way, disposing of these batteries is slightly hazardous. LR44 batteries can sometimes contain lead (ironically, the three I got from that capsule contains lead), which can be a hazard to garbage handlers if corroded or cut in half by the truck. Li-ion batteries, due to the heavy amount of metal in the batteries, can also cause soil contamination and water pollution. In 2015 a Kohl's department store in New Jersey had it's backroom catch fire due to Li-ion batteries scratching up against other batteries, as well as the metal container it was in. So, save the environment and your wallet ;)
