Customized 24V power battery for automatic rolling gate ◆The fumed silica is made of high-quality colloid, the electrolyte is evenly distributed, and there is no acid layering phenomenon; ◆The electrolyte is in a gel-fixed state, does not flow, does not leak, and makes all parts of the electrode plate react evenly; ◆Excess electrolyte, the battery has a large heat capacity, a strong heat dissipation capacity, and a wide operating temperature range; ◆European AMER-SIL company PVC-Si02 special colloidal battery separator, with high porosity, low resistance and good battery cycle life; ◆Very low electrolyte concentration, weak corrosion to the electrode plate, long battery life; ◆The positive and negative grids are made of lead-calcium multi-element alloy, and the battery self-discharge is low; ◆The battery has strong resistance to deep discharge. After 100% discharge, it can be connected to the load for four weeks, and the original capacity can still be restored after recharging; ◆Using high-sensitivity low-pressure valve makes the battery safer and more reliable.
