The cold shouldn’t be to detrimental to lithium with day to day use, similarly to the car won’t travel as far if battery is cold. However, storing for longer periods without use, its recommended to charge to the % the chair manufacturer recommends and preferably storing the battery somewhere it won’t be susceptible to freezing over a prolonged periods.
It’s used a couple of times a week. Was just worried after the cold weather last night and the battery chargers saying it was charged when I first plugged it in.
