Currently used in tens of millions of electronic toll tags, Tadiran Lithium thionyl chloride batteries have been trusted by the industry’s leading manufacturers to provide long life under extreme temperatures and environmental conditions.

Electronic road-toll transponders that are mounted on automotive windshields must be able to handle the severe temperature changes that characterize car interiors. For example, heat soak can hit 112°C (according to SAE) when a vehicle is parked, cooling down rapidly to room temperature. In cold weather, the battery must be able to handle cold soak and a rapid temperature rise.

For over a decade, Tadiran batteries have been selected for use in the E-ZPass system due to their unmatched ability to withstand extreme temperatures (-5°5C to +125°C). Tadiran batteries are also hermetically sealed, which is a major advantage over non-hermetically sealed systems such as lithium manganese dioxide coin cells that tend to “breathe” over large temperature cycles, with electrolyte material diffusing out of the battery while heating up, then air diffuses into the battery during cooling cycles.

In addition to electronic toll-tag transponders, Tadiran lithium thionyl chloride batteries can be found in a variety of automotive applications, including air bag deployers, emergency notification systems, GPS tracking devices, engine controllers, and tire pressure monitoring systems.

UL recognized, and compliant with lead-free RoHS and WEEE EC directives, Tadiran standard lithium batteries and custom battery packs are the battery of choice for electronic toll tags and other automotive applications.
