Maintaining correct tyre pressure on a vehicle is important for a number of reasons, if a tyre is under inflated, tyre life will be reduced by over 50%, fuel economy can be reduced by as much as 10%, and braking performance will be reduced by approximately 20%. This is obviously important to all road users for safety reasons but to businesses involved in transportation of any form of goods, materials or people; ensuring tyre pressure is correct is also important to reduce running costs of their vehicles.

With the development of wireless technology, a number of hi-tech, wireless digital tyre pressure monitors have been developed providing real-time data on the state of all the vehicles tyres even when in motion. Sensors either fit onto the valves of each tyre or can be internally wheel mounted, these sensors incorporate radio transmitters which transmit the data to a receiver unit which often has a display situated on the dashboard of the vehicle.

The receiver/display units generally run from a 12V DC power supply (often connected to the car's battery) with the sensors using batteries to power them. These units need to be compact, lightweight, reliable, and be able to operate for extended periods in harsh conditions, this specification links in with that of the battery used to power the sensors. The Sonnenschein and Tadiran product range offers a number of cells to meet such requirements in small sizes including BEL, 1/10D and 1/6D size cells. These cells have a high voltage and capacity ratings along with a wide operating temperature range with lightweight robust construction.

Take a look at the datasheets for the SL300 series button size cells:

SL340/P - 3.6V 0.40Ah BEL Size Cell
SL389/P - 3.6V 1.0Ah 1/10D Size Cell
SL386/P - 3.6V 1.7Ah 1/6D Size Cell
