Sony batteries with 4x cap
Sony on Wednesday announced it has released new olivine-type lithium iron batteries that have four times the capacity of conventional batteries from competitors. What's more, Sony claims the batteries can be charged to within 99 percent of their capacity in just 30 minutes. The batteries sport a power density of 1,800W/kg and a life span of 2,000 charge/discharge cycles.
The batteries, while slightly longer than AA batteries and thus limiting their use, will initially be the standard equipment for new power tools due to their quick-charging characteristics. They will then expand to power more mobile electronics devices.

...beyond any reason have sworn me off SONY forever - this company to lock up their markets in Microsoft-like ways (eg memory stick, betamax) & I suspect it is such a corporate culture that has contributed to a decline...
