CR123A & CR2

Originally invented for cameras that demanded high drain rates, then widely adopted by the flashlight industry, these cell types are increasingly called upon to power security and monitoring device due to their market-leading power density, shelf life, and stability across wide temperature ranges. Unlike flashlights and cameras, most alarm security and IoT (Internet of Things) devices have relatively low drain rates. This rapidly increasing usage in wireless IoT devices such as alarm sensors, security cameras, and monitoring devices has created demand for low-drain performance.

For nearly 2 decades, Titanium Innovations CR2 and CR123A lithium batteries have offered market leading performance and value. These improved cells are the result of a 4-year development process. Three important upgrades form the basis for the improvements; a new and fully automated winding process, an improved electrolyte, and a proprietary separator film. These three changes yield tighter tolerances, and equal or higher capacity at every discharge rate, resulting in improved performance, reliability, and safety

The new automated winding production line delivers a tighter and more consistent wind resulting in a 14% increase in rated capacity, and improved reliability yield, thus increasing product safety.

A proprietary electrolyte of modified Lithium Oxalyl Fluoroborate salt increases the cell capacity, operating temperature, and safety. Intrinsically non-hazardous, this new salt prevents thermal runaway under severe over-discharge conditions. This new chemistry is also responsible for the increased performance at extreme temperatures, increasing the tolerance range to from -4°F - 140°F to -40°F - 158°F.

A patent pending separator film and process creates a reaction-inhibiting region within the cell that prevents thermal runaway, and improves performance at high discharge rates.

The lithium belt negative electrode plate is grooved proximal to its electrode tab. The groove helps break the lithium belt in case of an overloaded discharge, or forced discharge (reversed charge).

These added layers of safety, in addition to the pre-existing safety features, such as PTC protection, a chemical fuse, and integrated vents make the new CR123A and CR2 primary lithium cells from Titanium Innovations a leader in performance, and safety.
