The core function of base station batteries is to provide uninterrupted backup power. When the mains power is normal, it silently stands by to charge; Once the mains power is interrupted, it immediately discharges and continues to supply power to the base station equipment for several hours or even longer until the mains power is restored or the oil engine is started. Its design life is usually 10-15 years, which matches the update cycle of communication equipment and has explosion-proof and liquid blocking functions to prevent accidents caused by excessive internal pressure; Maintenance free: No need to add liquid or water, the sealed design can be placed vertically, horizontally, or stacked.
