Charging a cabinet battery at temperatures below 0°C can be problematic. At low temperatures, the electrolyte inside the battery becomes more viscous, which increases the internal resistance. . The diaphragm melts or shrinks, causing the positive and negative materials to contact and short circuit, and there are hidden dangers such as explosion and combustion. This range ensures optimal performance and longevity of the battery. Notwithstanding these settings, we have noticed increasing maximum. . The optimal temperature range for most battery types, including lithium-ion, is between 20°C and 25°C (68°F to 77°F).
