City Labs Inc., a minority-owned startup company based in South Florida, is the innovator and manufacturer of long-life NanoTritium™ batteries for microelectronics, sensors and other small devices used in defense, homeland security and medical implants. Founded in 2005, the company’s team of scientists and engineers has developed batteries with a lifetime of over 20+ years without requiring replenishment that can power a range of devices where battery replacement is difficult or impossible. The City Labs battery is resistant to extreme temperature variance (-50 degrees C to +150 degrees C), as well as extreme vibration and altitude, due to the fact that it is based on the decay of Tritium, a radioisotope used as an illumination source for Exit signs commonly found in schools, theatres, commercial buildings and aircraft. 


City Labs’ Tritium batteries enable applications where a source of continuous nanowatt/microwatt power for twenty years or more is crucial. Applications include intelligence-gathering sensors, medical implants, space satellite and probe power sources, trickle charging lithium batteries, semi-passive and active RFIDs (radio frequency identification), subsea sensors and buoys, wireless dust mote networks and field sensors, smart munitions, memory backup and lower power processors (e.g. ASICs, FPGAs, MicroController Units, etc.). City Labs’ battery also serves as a vital  component for the defense and security of electronics.
