Never used a rechargeable but did for a time have a Black and Decker electric mower. Had a cord you had to manage. It worked well but the thing I REALLY disliked about it was that the motor sounded like the Mother Queen of all Winged Stingers and attracted copious amounts of wasps, yellow jackets, bees, mud daubers, and anything else you could imagine. Within minutes of turning it on it had numerous unwanted winged insects buzzing around it! Had to get rid of it in a few months, it was that bad. Now for a few years have had a Craftsman decked mulching mower with a Honda GCV 160 engine. Easy start, mows great, and no wasps to contend with!
