The strong exothermic nature of the discharge chemical reaction may cause a large increase in temperature rise near the end of discharge. This is compounded by the fact that many times, the load on a battery is constant-power in nature. As the battery voltage decreases near the end of its capacity, the current must increase to maintain constant-
