Amaron Quanta SMF battery Dealer The term "SMF battery" stands for "Sealed Maintenance Free battery." SMF batteries are valve-regulated lead-acid (VRLA) batteries, meaning that they are designed to be maintenance-free and do not require the addition of water or electrolyte throughout their service life. These batteries are sealed, which means that the electrolyte is immobilized and cannot be spilled even if the battery is turned upside down. SMF batteries are commonly used in various applications, including uninterruptible power supplies (UPS), emergency lighting, security systems, telecommunications, and other standby power applications. #Amaron Quanta SMF battery Dealer
