Wondering how batteries perform in frigid extreme cold? Today we’re sharing the real low-temperature discharge test of our TOP 41Ah cell at -40℃!

First, let’s check the discharge curve. At -40℃, the voltage stays stable in the early stage and declines gently as capacity releases, demonstrating excellent voltage retention performance. The test followed rigorous procedures: after standard charging, the cell was stored in an environment of -40±2℃ for 8 hours, then discharged at 1C current down to 2.0V. With a nominal capacity of 41Ah, the actual discharged capacity reached 39.63Ah, delivering a discharge efficiency of 96.65% — far exceeding expectations!

Boasting an energy density of 400Wh/kg, this cell maintains outstanding performance even in extreme cold. It stands out perfectly for outdoor expeditions, operations in frigid zones, and all scenarios demanding superior cold resistance, reliably powering your devices with steady endurance. It’s a top pick for your low-temperature battery shortlist!

The exceptional performance of our battery at -40℃ ultra-low temperature once again validates our leading edge in battery technology. Moving forward, we will keep pushing the performance limits of batteries and deliver dependable energy solutions for all kinds of extreme-environment applications.
