Lithium iron phosphate (LiFePO4) batteries have become the preferred choice due to their high energy density, long cycle life, thermal stability, and safety. Telecommunication battery (telecom battery), also known as telecom backup battery or telecom battery bank, primarily refer to the backup power systems used in base stations and are a core component of these systems. However, their applications extend far beyond this. They are also frequently used. Base station batteries typically remain on continuous float charge for months or years, only discharging during grid outages. Reliability during rare events is more important than frequent cycling. In such scenarios, batteries serve as the “lifeline” of communication.
