Battery-Powered String Trimmer

The Battery-Powered String Trimmer is a relatively low-cost choice for the smaller lawn trimming jobs. Being cordless, range of motion is not restricted by an extension cord. It can reportedly be operated continuously up to one hour before recharge is necessary, is quiet, and doesn’t require the mixing of fuel as does its heavier gas-powered counterparts.

Cost: $70-$280, depending on battery type/voltage, rpm, accessories, etc.
