This significant discrepancy suggests that the original specification was highly overstated. Given its 2-year age and rare usage, the low capacity is more likely due to inaccurate manufacturer claims rather than degradation over time, as lithium batteries typically maintain performance with infrequent use.",

Despite the fast discharge over 56 hours, the battery's performance suggests it should still work well in devices that can tolerate slightly reduced voltage levels before complete discharge. With its expiration next month, its performance may be slightly diminished but remains solid for low to moderate current-draw applications.",
