Porter-Cable added the Battery Status Indicator (PCC580B) to its 18-volt Lithium Ion and NiCad tool lines to help contractors make that quick check that could save hours. The indicator slides onto the battery and automatically displays the power level on its LED screen, shutting off after 15 seconds. The indicator comes with a three-year limited warranty, a one-year service contract, and a 90-day money-back guarantee. 888.848.5175. www.portercable.com.
