Electrical equipment is easier to service a fact. The most obvious advantage of electric yard equipment (whether battery-operated or corded) is that no gas engine maintenance is required - no oil changes, spark plugs, or air filters. And if you store it for the winter, there's no inherent fear that it won't start in the spring. In fact, gas equipment can act fussy without proper maintenance (and most people don't care about proper maintenance). In contrast, electric equipment behaves pretty well with minimal supervision. Well, if you need more serious equipment.
