9 Volt (LiMnO2)
The world’s longest lasting Lithium 9 Volt – over 100 million sold worldwide

- Whilst the competition offers lithium 9V products that boast 800mAh of capacity, ULTRALIFE’s battery offers 1200mAh, or 50% more energy than the nearest brand name competitor.
- Extremely lightweight, ULTRALIFE’s lithium 9V weighs 37g, approximately 18% less than the average alkaline 9V.
- ULTRALIFE’s 9V also has a low internal impedance, increasing the ability for the battery to supply higher power output with a stable voltage.
- Designed for demanding applications, this 9V battery operates from -20°C to +60°C while maintaining an exceptionally low magnetic signature.
- Meets leading international safety and transportation standards, including UL 2054, IEC 60086-4:2014, and UN 38.3, and is approved for use in UL 217-compliant smoke alarms.
- Designed as a seamless replacement for standard alkaline 9V batteries, with ANSI 1604-compliant dimensions that enable drop-in compatibility with existing devices.
