Lithium battery manufacturer Tadiran Batteries has introduced an improved version of its PulsesPlus™ battery that allows for an indication at end-of-life, allowing end users to maximise the service life of the original battery while at the same time ensuring continuous service through scheduled battery replacements.

Lithium thionyl chloride batteries are typically used in applications where battery replacement or recharging is either impossible or extremely difficult, such as automatic meter reading and wireless remote sensors.

While lithium thionyl chloride cells operate at a very stable voltage over almost their entire operating lives, the lack of a drop in voltage over time has not allowed for an indication of battery state of charge. In many cases, batteries are replaced prematurely based on estimations of amount of remaining battery life, even though the cells could continue to operate for years to come.

PulsesPlus batteries come in two families – a 3.6 V system with a 5 percent end-of-life indication and a 3.9 V system with a 10 percent end-of-life indication. Based upon the selected PulsesPlus system, there will be notification 1 to 2 years before the battery reaches its end-of-life – providing more than enough time to schedule replacements. This will allow longer operating time for devices and save on replacement costs.
