Battery power backup systems are commonly used to power critical devices during power outages. They can provide power for a certain period of time, depending on the capacity of the battery and the electricity demands of the devices plugged into the system.
A battery backup system includes the following components:
The batteries in power backup systems differ from one another depending on the materials used to create them. These differences are called “chemistries.” Most power backup systems use one of two chemistries, Lithium Nickel Manganese Cobalt Oxide (Li NMC) or Lithium Iron Phosphate (LiFEPO4). Each has their advantages and disadvantages

Battery Chemistry The composition of a battery that determines its energy storage, power delivery, charging, lifespan, and safety characteristics | LiFePO4 | LiFePO4 | LiFePO4 |
Cycle Life: The number of times a battery can be charged and discharged until it falls below 80% of its original capacity. A higher number means a longer lifespan. | 3,500 Approximately 10 years | 3,500 Approximately 10 years | 3000 Approximately 10 years |
Depth of Discharge: How much battery can be drained without causing damage over time. | 80% - 90% | 80% - 90% | 80% - 90% |
Stability: How the battery performs at elevated temperatures. | Does not overheat or catch fire | Does not overheat or catch fire | Does not overheat or catch fire |
Energy Density: The weight and size battery required to hold the same amount of energy. | Heavier | Heavier | Lighter |
