Q1 It is sensitive to high temperatures. ➨If the battery is completely discharged, it can no longer be recharged again. ➨It is relatively expensive. ➨If the "separator" gets damaged, it can burst into flames. Q5 Water taste is similar whether room temp or from the fridge; The water we drink contains chlorine (used for disinfecting) and minerals (calcium, magnesium, sodium, potassium, etc.). These impurities affect the boiling and melting points of the water. Can we drink pure water? Yes,but pure water has no color, taste, or smell because there are no minerals or trace elements. Simple reply but...? KR IRS 5823
