The city of Detroit has over 3,400 parking meters. If they were all functional, it's estimated they could bring in an additional $6 million per year in revenue. That's money the city could desperately use. Instead, only about half are working, a spokesman for Emergency Manager Kevyn Orr told The Detroit News. The reasons for this are alarmingly easy to fix.
First, as part of the city's austerity measures, it switched to a cheaper, lower-quality battery. According to The News, BatteryJunction.com claims the current batteries being used by the city are nearly three dollars cheaper than the Duracell CopperTop nine-volts the city used before it went bust.
According to an anonymous meter attendant, the Duracells were swapped out every summer and winter. These new batteries, though, are dead well before attendants can get there with replacements. So yes, money is being saved somewhere, but revenue isn't being realized elsewhere.
