Introduction: Free Batteries in Try Me Buttons

Picture of 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 ;)

Nice life hack. Button cell batteries are expensive to buy

A store near me sells them 3 for $5. Either way, whatever price, free is better than paid.

3 for 5$ (US I suppose) That's the rip-off people get that are too old to know how to use the internet. Or just _need_ it NOW. And not tomorrow or the day after and are therefore willing (forced) to pay premium.

Free is better than paid? It may look like that, but that's not correct. In fact there ain't no no such thing as a free lunch.

Yes, you may get some <devices> into your hand for free and they may hold some batteries that you can salvage easily. Great! But now you have to store them until you need / can use them. Are they still fresh then? Were they fresh when you got salvaged them? Perhaps they sat some months/years on a shelf. Will they work when you need them? No problem if it is just for a fun project, But what if it just _has_ to work? I'd happily pay for a dozen of them, test ten of them till dead and only use two of the pack to be sure they _will_ work.

So, yes, most of the time free is best. But sometimes, just sometimes ... paying for stuff may be a good idea.

But 3 for 5$ is still a rip-off...
