> Around town, some people teased him that his E.V. battery eventually would stop holding a charge, just like battery-powered hand tools do. I wish the journalist dug into this more; NiCd and NiMH battery powered tools were abysmal for life; ~3 years of home projects and trying to defeat memory effects were a huge problem in the early 2000s. But these days, lithium ion tool sets are more versatile (all upgraded to 20v, versus 12v had been a norm NiCD) but now they're lasting 10 years, assuming you don't leave them off of the charger when they're dead.
