Wicked Tek4 battery technology runs compact Ryobi accessories

I'm a huge fan of lithium-ion battery technology.  Lithium-ion holds a full charge for up to 18 months without draining, it's quick to charge and doesn't have the 'memory' problem that NiCad batteries have (i.e. if you don't charge them fully, they forget that they have extra storage, so they just get lamer and lamer over time until they're barely taking a charge at all). 

I wish some manufacturer would produce rechargeable AA and AAA lithium-ion batteries but until that happens, Ryobi has created the Tek 4 lithium-ion battery (which contains enough juice to match three regular AA batteries).  And they've also developed a bunch of very cool accessories that run on Tek 4, including noise suppression headphones that rock your own tunes, cell phone chargers, cameras etc.  Available at the Home Depot.




The problem with AA and AAA batteries is they lack circuit protection and can't be made rechargeable using lithium-ion without too much of a fire risk.
