Currently used in hundreds of millions of automotive electronic toll tags, Tadiran bobbin-type lithium thionyl chloride (LiSOCl2) batteries are trusted by leading manufacturers to provide long life reliability 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.


Tadiran batteries are the preferred solution for electronic toll tag systems due to their unmatched ability to withstand extreme temperatures (-55°C 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 may leak over large temperature cycles, with electrolyte material diffusing out of the battery while heating up, causing corrosion.


In addition to electronic toll-tag transponders, Tadiran bobbin-type LiSOCl2 batteries are utilized in a wide variety of automotive applications, including air bag systems, emergency notification (e-Call) systems, GPS asset tracking devices, engine controllers, and tire pressure monitoring systems.


UL recognized, and approved for lead-free RoHS, WEEE EC, and REACH directives, Tadiran lithium batteries and custom battery packs are ideal for use in electronic toll tags and other automotive applications.
