3.6-volt lithium batteries are commonly used for wireless alarms in home security systems, memory backup in computers and other small electronics, bar code scanners in retail environments, calculators and military applications. Unlike secondary lithium batteries found in laptops and cellular phones, 3.6-volt primary lithium batteries are disposable, offer a higher energy density, have a shelf life that ranges from 7-10 years and operate at a wider temperature range.
Further uses for 3.6-volt lithium batteries include utility metering, automatic meter reading, tollgate systems, automotive electronics and computer real-time clocks. The ability to operate at an extreme range of temperature (as low as -67°F and as high as 257°F) makes them a good choice for outdoor applications such as dog collar tracking devices, electronic fences and scuba-diving equipment.
The batteries have a high voltage response, low self-discharge rate and good resistance to atmospheric corrosion. They come in a variety of shapes and sizes, including AA, C, D and wafer cells. 3.6-volt batteries are non-rechargeable.
Industrial brands that manufacture 3.6-volt batteries include Saft, Tadiran and Xeno. Consumer brands manufacturing them include Duracell, Energizer, Panasonic, Renata, Sanyo and Varta.
Due to shipping regulations set by the Department of Transportation in 2005, 3.6-volt lithium batteries can only be shipped by certified shippers due to a high amount of lithium content.
