Description

In high-mode flashlight testing, alkaline and Ni-MH batteries gradually lose brightness. Ostation 1.5V Li-ion maintains a stable 1.5V output throughout the test, delivering reliable, consistent performance when it matters most. Under identical lab conditions, Ostation 1.5V Li-ion delivers 489 full-power flash shots, outperforming Ni-MH (421) and alkaline (408). That means more shots per charge, fewer interruptions, and longer-lasting power for high-drain devices.
