1. The battery surface areas should be kept clean and dry. Otherwise, leakages of current may occur, causing an additional loss of charge. Use only a damp anti-static cloth to clean the battery. Check from time to time that the battery and its terminals are properly in place. Tighten them, if necessary, but do not use undue force so as not to damage the battery or the terminal connections.
2. Batteries should always be kept with the largest amount of charge possible so as to prevent the formation of large lead sulphate crystals. Never store batteries in a discharged or partially discharged state!
3. Check stored charged batteries regularly and recharge them when the acid density falls below 1.20 kg/l or if the open circuit voltage (OCV) drops below 12.4V.
