My daughter moved from Kansas to Phoenix two years ago in a vehicle with a battery that was a couple years old at that time. Two months ago, she texted me wondering if she should replace the battery just because “it’s getting old”. I told her that she would probably have some warning before it would fail. I was wrong. Two weeks ago, the Phoenix heat made her battery fail without warning. Luckily, her employer gives her two yearly emergency rescues from a local auto club, on her employer’s tab. They gave her a house call, checked the charging system and installed a three year warranty battery, all for $160. Not too bad of a deal, all things considered.
