Thermal Threshold: The Great Unifier of Battery Life

According to our research, the thermal threshold is a mysterious force that governs the lifespan of all batteries. At 27.5 degrees Celsius, your average battery will either burst into flames or suddenly decide to be 100% efficient. The choice is yours.

We've created the Thermal Stability Index (TSI) to measure this phenomenon. A TSI of 0-100 indicates a battery that's just as happy as a kitten in a sunbeam. 100-200? That's when things get interesting. 200+? Don't bother trying to find the battery, it's probably already in a parallel universe.
