Ok, you pulled me back for one comment since you seemingly loosened up about it. He got more precise answers first, so I figured it was relevant in the sense that rechargable batteries are always relevant to try first and thought i gave a thoughtworthy reason to why. Sure, some cheaper ones are of bad quality and may not be able to sufficiantly power an item, but for the most part they do. Like controllers and similar devices. Even a rechargable battery that runs out of charge quicker than others, is still a better choice to a non rechargable battery for obvious reasons. I run only rechargable batteries from anything like game controllers, tv controllers, flashlights, laser sights and airsoft guns. Its just plain ignorant not to use them when you can. Use a high quality charger and its very efficiant too.
And there are plenty of options to dirty electricity out there if you just look around actively.. Ive ran my apartment on 100% windpower for the past 10 years, and next year i will be able to switch to wave power. It may not be the most relevant addition to the thread elaborating on this, i can agree to that, but if people continue in the tracks we are in now, "use and throw away", we wont be around for much longer. I think that is worth considering while talking about rechargable batteries vs non rechargable. Its as relevant as any other reason to use the forementioned kind.
