Lithium 9V/PP3
Lithium 9-volt batteries are consumer-replaceable, high energy density batteries designed to last up to 5 times longer than alkaline 9-volt batteries and up to 10 times longer than carbon-zinc 9-volt batteries in many applications. In addition, lithium PP3 batteries have a long shelf life of up to 10 years. Common applications for lithium 9-volt batteries are smoke / CO (Carbon Monoxide) alarms, and electronic parking meters.
