法國(guó)POWER-SONIC蓄電池PDC-1285  12V8.5AH太陽(yáng)能儲(chǔ)存電源

蓄電池與地面之間應(yīng)采取絕緣措施，墊木板或其他絕緣物，以免蓄電池與地面短路而放電。如果蓄電池?cái)?shù)量較多時(shí)，可以安裝在蓄電池專(zhuān)用支架上，且支架要可靠接地。

蓄電池安裝結(jié)束，要測(cè)量蓄電池的總電壓和單只電壓，單只電壓大小要相等。接線時(shí)辨清正負(fù)極，保證接線質(zhì)量。

蓄電池極柱與接線間必須緊密接觸，并在極柱與連接點(diǎn)涂一層凡士林油膜，以防腐蝕生銹造成接觸不良

Short circuit phenomenon is manifested in: the open circuit voltage of the battery is low, the electrolyte density is lower than that of other batteries, there is no gas or gas leakage occurs very late during charging, the electrolyte temperature is higher than that of other single cell batteries, and the electrolyte density and charging voltage increase less or even remain unchanged. When discharging, the capacity is small, the voltage drops , and it is easy to cause sulfation of the electrode plate. After removing the electrode group, check that the positive electrode plate changes from dark brown to light brown, and the negative electrode plate changes from light gray to gray white. Moreover, the feel is hard and there are signs of short circuit.

The reason for an internal short circuit in a battery is that a conductive object falls into the battery, causing a short circuit between the positive and negative plates, or a "lead bean" causes a short circuit between the positive and negative electrodes during welding and assembly. The perforation or pore size of the separator may cause the "lead velvet" formed by the electrode plate to penetrate the separator during charging and discharging, causing a short circuit. The electrode plate will bend and deform, causing damage to the separator or the detachment of active substances, which will precipitate at the lower edge of the electrode plate and cause a short circuit.
