Battery: special plate design, long cycle life, special lead-calcium alloy formula, enhances the corrosion resistance of the grid, extends the service life of the battery, the partition enhances the internal performance of the battery, the heat capacity is large, reduces the risk of thermal runaway, is not easy to dry, can be used in harsh environments, high gas recombination efficiency, very little water loss without electrolyte layer phenomenon.
Battery: All online and backup/online hybrid UPS than backup or online interactive UPS operation heat is larger (so the former to install a fan), which is also a backup or online interactive UPS battery replacement cycle is relatively long an important reason, charging affects the battery charger UPS is a very important part of the UPS.

Battery: The positive electrode on the battery is generally covered by a red protective cover, there is also a black, there is a “+” symbol above, the other end is the negative electrode, the negative electrode is generally no protective cover, it is easy to distinguish. The voltage of the car battery is mostly 12V, and the normal life is 3-5 years.
