Yeah, but considering how small the amount of energy is that batteries can store, even those that use Lithium make for a very poor energy storage. > The disadvantage of lithium is that it is expensive. Batteries have always been expensive, and they still are.

Then why aren't there dramatically better batteries available yet? When I was a child, I had an RC car, and it would run about 1/2 hour before the battery was empty. Then it would take so long to recharge that you could use it only once a day, maybe twice if you started early. Then the batteries of the control device would be empty and needed to recharge for a day. I have a Magcharger, and it's useable for only about an hour, then takes 10--16 hours to recharge. After not even 1/2 year, its battery seems to be on the way out, despite treating it well. I've used two different cell phones, and unless you actually talk to someone (i. e. use it), the battery lasts only a few days. If you use them, the battery is empty after about two hours. It's ridiculous. And are there any batteries yet that are up to the temperature specifications for mobile devices? Even the ones you get for Magchargers aren't. I have a GPS device, and its battery is almost always empty --- even if it's not, it lasts maybe 20--30 minutes at best. Batteries just suck, and I don't see that changing any time soon, if ever. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
