Why is charging voltage so critical to both gel and sealed lead acid batteries? 


A: Charge voltage is critical on these types of batteries because they both are recombinant batteries. This means that the oxygen that is normally produced on the positive plate in all lead acid batteries recombines with the hydrogen given off by the negative plate. The “recombination” of hydrogen and oxygen produces water, which replaces the moisture in the battery. Therefore the battery is maintenance free and never needs watering.


The sealing vent is critical to the performance of a sealed battery. The cell must maintain a positive internal pressure, otherwise the recombination of the gasses will not take place and the cell will dry out and not perform.


In addition, the valve must safely release any excess pressure that may be produced during overcharging, otherwise the cell would be irreparably damaged. It is because of the safety mechanism of the valve that overcharging hurts a sealed battery. 
The excessive pressure that the valve is releasing is both hydrogen and oxygen. The more you overcharge a battery, there is less oxygen and hydrogen left inside the battery to recombine and create water. In essence, the battery dries out. 


It’s important to note that a sealed battery must never be opened once it leaves the factory. If opened, the cell loses its pressure, and the outside air will “poison” the plates and cause an imbalance that destroys the recombination chemistry. 


Hence the name: Sealed, Valve Regulated (SVR) Battery. 


The correct charging voltage for a Gel battery is 14.4 to 14.6 volts maximum at 68°F. The correct charging voltage for our Absorbed lead acid battery is 14.4 to 14.6 volts maximum at 68°F.
为什么充电电压对凝胶和密封铅酸蓄电池都至关重要?


答:充电电压对这些电池是至关重要的,因为它们都是重组电池。这意味着氧气,通常是对所有铅酸蓄电池正极板产生的重组与关闭的负极板氢。氢和氧的“重组”产生了水,代替了电池中的水分。因此电池是免维护的,从不需要浇水。
密封通风孔对密封电池的性能至关重要。电池必须保持一个正的内压,否则气体的重组不会发生,细胞会干出来,不执行。
此外,阀门必须安全地释放多余压力过程中可能产生的充电,否则电池会造成不可修复的损坏。正是因为这种滥伤密封电池的安全阀机制。
阀门释放的过大的压力是氢和氧。电池充电过多,电池内的氧和氢就会减少,重新组合并产生水。在本质上,电池干涸。
重要的是要注意,密封电池一旦出厂就不能打开。如果打开,细胞失去压力,外界空气将“毒害”板块并造成破坏重组化学的不平衡。
因此名称:密封阀控(SVR)电池。
正确的充电电压为凝胶电池是14.4至14.6伏最大在68°F。正确的充电电压为我们的吸收铅酸电池是14.4至14.6伏最大在68°F。
