Five years ago in tools of the trade a test of the first generation of lithium-ion–powered reciprocating saws determined that for getting the job done quickly, 36-volt tools were the ones to buy—most 18-volt models weren't up to jobsite challenges. But I'm happy to report that advancements in motor and battery technology make some of the newer 18-volt models capable of serious work. They're worth considering to add cordless convenience to your demolition and other recip-saw jobs.
I tested the tools in kit form with a battery, charger, and carrying case (where available). Keep in mind that these saws are also sold without batteries or chargers (referred to as "bare tools") for users who already have batteries and chargers from the same manufacturer.
