San Yang Yang Battery Battery SP12-200 St. Features: Maintenance is simple: This series battery with good corrosion resistance as special lead-calcium alloy grid, ultra-fine glass fiber separator, the use of cathode absorption technology, internal oxygen cyclic compound, so the battery to achieve a seal over the life without regular maintenance such as water or acid supplement safe: safety valve opening and closing the valve performance, long life, either as a result of the release of excess gas operator error or overcharge caused to ensure the security, but also to prevent outside air from entering the battery or Mars or bursting caused by self-discharge self-discharge: due to the use of special alloys for battery grids, and various impurities in the electrolyte separator production process is strictly controlled Therefore, low self-discharge and reliable sealing: imported resin glue, seal and ABS form corrosive and excellent toughness after curing adhesive, thus ensuring no leakage of acid resistance is small:.. plate bus poles and other uses optimized design, clapboard resistance is very low, so a small battery internal resistance, good high-current discharge performance recovery performance: high quality grid alloy, excellent and stable technology, a unique formula of electrolyte additives make deep discharge battery after long fully charged, the battery capacity is not substantially reduce product installation products based on user needs vertical rack cabinet placed horizontal ground and built-in cabinets and other power use and other forms of Conditions of Use:... the best environment temperature 15 ~ 25 ℃ can get a longer life
