Do scales become in-accurate when the batteries are low?
I'm not sure if my scales are messing about as they are low on battery or if i really do weigh that much? I lost 7.5 inches from my body but it's saying that I've gained 3lbs. I decided to weigh in at my friends house and her scales said i lost 3lbs , i'm not sure whether mine are right and I've gained muscle or whether…
