I use a lot of batteries. For my computer, I make use of a wireless desktop system with a wireless keyboard and mouse, both of which require rechargeable AA batteries. I have several controllers for the Xbox 360 and these all need AA batteries. I have a couple of digital cameras that use AA batteries too. That’s a lot.
As such, it’s important to me to always have a supply of batteries ready to go, just in case the set inside one of my devices happens to run dry. It’d be so much more convenient if these batteries could last longer and charge up faster. Sony agrees.
The newest batch of lithium-ion batteries from Sony offer both of these very important characteristics. The batteries feature an olivine-type lithium iron phosphate and this pushes out more power, apparently. Further still, it can top up to 99% of its capacity in just 30 minutes.
That’s the good news. The bad news is that these batteries have only been shipping for use with power tools (that’s why the label is so basic), but I’m thinking that Sony will be pushing similar tech into their more consumer-ready offerings at some point in the future too.
