If there is one thing that male tech bloggers will profess is that sitting in front of multiple computer screens 14+ hours a day doesn’t exactly breed metrosexual hygiene. Certain daily tasks like shaving takes a back seat if we’re to be on top of the daily tech news. I’m not saying that we’re a stinky or dirty crowd, but come on, we are the faceless army of the Internet. Maybe this USB rechargeable shaver is novel enough to actually be used on our peach fuzz though. Plus, it’s only $22 bucks so most of us could actually afford it on our measly income.

Today Sanyo announced that from September 12, they will be offering C and D-sized rechargeable eneloop batteries.

However, the lineup of AA and AAA-sized batteries will be expanded in Japan first. Sanyo hasn’t talked about release dates or prices for other markets yet. In Japan, one C-sized battery will cost $13 (D-size version: $15).

The batteries are rechargeable up to 1,000 times. Sanyo will roll out a universal charger, also on September 12, which is suitable for eneloop batteries of all sizes. It will be sold in Japan for $48.

Following the lead of Nissan and NEC, which both recently have started down this track, the German carmaker is looking into lithium-ion batteries to improve its hybrids and electrics. It sounds like the Nickel-metal hydride (NiMH) batteries in their cars are both heavier and more toxic than the alternative.

The Li-ion batteries would lower the weight of the car by hundreds of pounds, improving handling and mileage. You’ve already got them in your phones, media players, and so on, but adapting them for the high-capacity, high-throughput application of powering a car is a serious endeavor — which must be why Sanyo is pledging nearly a billion dollars over the next couple years to developing the technology.
