韩国火箭ROCKET蓄电池L-890 8V190AH气体再化合技术
检查项目包括：整组电池的浮充电压，单体电池浮充电压，测单体电池电压时，应在电池放电状态下进行，否则测得的结果会是假电压，经验作法是在测量时，万用表两端并联一个1-3欧姆的电阻丝；检查电池是否损坏，壳、盖间有无泄漏，表面是否有灰尘等杂物，电池架、连接线、端子是否有松动或锈蚀等。
超量电解液空间设计 极板上部超大空间设计：比常规电池高出10mm以上。在高温下，电解液蒸发时间延长1/3，有效延长免维护电池的使用寿命。
Super electrolyte space design:The upper part of the electrode plate has a super large spacedesign, which is more than 10mm higher than conventional batteries.At high temperatures, the evaporation time of the electrolyte isextended by one-third, effectively extending the service life ofmaintenance free batteries.
Cold forging pole technologymakes the surface of the pole hard and crack free. Effectivelyprevent pole climbing acid.
Special pole protection creamtechnology: prevents pole oxidation, making the pole smoother andharder.
The positive electrode gridadopts a special coating material formula, effectively increasingits resistance to low temperature and high heat, and extending itsservice life.
High purity materials, specialprocess grid: high-purity lead, high- calcium, aluminumalloy, area dense tensile grid, effectively enhancing gridstrength, corrosion resistance, overcharging resistance, reducingself discharge, and high temperature resistance.
