Had mine 9 years. Have to replace battery twice ($15 @ radio shack. Its a std 12V dry cell) now worn out i just searched Hi and low for another as this is a discontinued model. Its still the best for 1/4 acre lots and smaller. Lite, Ergonomic and less of a pain than corded or gas. You will not be disappointed. This is better that the 18V Nicad versions since it can half-recharge and not have battery memory issues.
