The reasoning behind dual batteries was the imposing by airlines on the battery voltage you could take on board, the manufacturers got over this by introducing the dual battery.
a modern cordless might be cometitive, but almost 3 x the weight to hold up. my 110V weighs in at under 4lb. a decent cordless battery weighs more.
soon get power to anywhere with these guys.Definitely and that remains the single greatest advantage of corded tools - at least it is in locations where power is available.
Trade rated tools that can take a dual batter are a totally different tool/battery to the mass produced multiple use batteries for domestic use, it's to do with the duty cycle and comparing them both.There's also the fact that it's easier to sell tools if they all use they same batteries, which might explain why not all manufacturers have gone down the twin battery route. It's very likely that manufacturers find it easier to sell tools when they all use the same batteries.
