Lithium Coin Cells or ® ULTRALIFE Thin Cells Are today’s coin cells struggling to meet the demands of modern wireless applications where a new set of performance attributes are required?

“When devices must operate 24/7, most portable IoT device manufacturers return to the battery” The chatter surrounding the Internet of Things (IoT) speaks volumes about the interconnection of smart devices but not so much as to how they should be powered. For IoT devices which are designed to exist ‘off grid’ they must source their electrical energy from somewhere, whether that be a traditional battery, or one of many energy harvesting techniques such as solar or kinetic scavenging. For long term reliability, when devices must operate 24/7, most portable IoT device manufacturers return to...

COIN CELLS Lithium coin cells range in capacity from 10mAh to 1000mAh and are ideal for applications which operate at or around room temperature where the discharge current is low and constant, with few peak demands. Due to their relatively high internal resistance, coin cells have difficulty providing high pulses of current (such as RF transmission pulses) and low temperature operation (<0°C) can range from poor to non-existent. ULTRALIFE® Thin Cells Coin cells do however have the advantage that they are available in many standard sizes and from multiple manufacturers. They are easily...

Discharge Performance The following charts compare the discharge performance of an ULTRALIFE® CP124920 Thin Cell to CR2025 coin cells from three different Tier-1 manufacturers. This test demonstrates the performance advantage of the ULTRALIFE® Thin Cells over the coin cells when subjected to a high rate discharge. The test uses a 65Ω constant resistance load which discharges the cells at between 31mA and 43mA. The test was conducted at room temperature (+20°C). The superior discharge capability of the ULTRALIFE® Thin Cell is clearly shown in this test. In real life applications it is more...
