1. Ultra-low self-discharge & super long shelf life
Annual self-discharge ≤1% at room temperature. Shelf life can reach 10 years. It can power equipment steadily for many years without replacement.
2. High energy density
It has the highest energy density among primary lithium batteries, large capacity in a compact D-size cylinder.
3. Extra-wide working temperature
Normal operation from -55℃ to +85℃, perfect for outdoor, desert, alpine and underground meter projects.
4. Flat discharge plateau
The discharge voltage stays stable at around 3.6V for most of its service life, no obvious voltage drop before depletion.
5. High safety performance
Hermetically sealed metal shell, with safety vent design. It meets IEC, UL and intrinsic safety standards for instrumentation.
