卓越性能12V车载电池：
----复合分离器
超细玻璃纤维复合隔膜，在硫酸溶液中重量轻，电阻小，酸度高，吸附力强，离子迁移能力强，电池电压和起动电流最大化，保持电池容量处于良好状态长。
---通用分离器与复合分离器的使用寿命比较
纤维直径为2-3um的超细玻璃纤维复合隔膜在网络结构中无序布置。电池电解液的强吸附和破坏能力可以有效地冷凝活性物质，防止其脱落，从而延长电池寿命。
- -电池寿命
采用无铅Pb-Sn-Ca特殊合金化技术有效地保证了正极板和负极板中二氧化铅和海绵铅的含量。电池加液后可直接投入使用，无需充电。其超高性能将产品与其他产品区分开来。
--- Pb-Ca合金性能优良
由高纯度Pb-Ca合金制成的积层板具有非凡的抗氧化和耐腐蚀能力。避免了普通锑合金板析氢造成的不利影响;蓄能器的水损失减慢，循环指数提高。
---一般自给自足的比较
蓄电池和Pb-Sb-Ca合金蓄电池
Pb-Sb-Ca合金网格比一般的Sb合金网格具有更好的耐氧化性，耐腐蚀性和更少的水分损失特性，可以使自放电最小化，并且即使在长期储存后也能保持良好的起动性能。

Superior performance 12V car battery :
----Composite Separator
Ultra-fine glass fiber composite separator, with light weight, small resistance, high acidity absorption and strong ion migration ability in the sulfuric acid solution, improves its battery voltage and starting current to the maximum, thus keeping the battery capacity in a good state all long.
---Comparison of Service Life between General Separator and Composite Separator
Ultra-fine glass fiber composite separator, with the fiber diameter of 2-3um, is arranged disorderly in a network structure. The strong adsorption and breakover capabilities of the battery electrolyte can effectively condensate active substances and prevent them from dropping off, thus extending the battery life.
---Battery Life
The adoption of Sb-free Pb-Sn-Ca special alloying technology effectively guarantees the contents of lead dioxide and spongy lead in the positive and negative plates. The battery can be put into use directly after adding liquid, no need to be charged. Its super-charged performance distinguishes the product from others.
---Excellent Performance Chart of Pb-Ca Alloy
The accumulate plate made of high-purity Pb-Ca alloy has extraordinary oxidation and corrosion resistance capabilities. The adverse effect brought about by hydrogen evolution of general Sb alloy plate is avoided; the water loss of the accumulator slowed down, and the cycle index improved.
---Comparison of Self-discharge between General
Accumulator and Pb-Sb-Ca Alloy Accumulator
The Pb-Sb-Ca alloy grid offers more excellent characteristics of oxidation resistance, corrosion resistance and less water loss than the general Sb alloy grid, which can minimize the self-discharge and maintain its good starting performance even after long-term storage.
