Which Type of UPS Battery Is Better?
Currently, there are two main types of UPS batteries on the market: lead-acid batteries and lithium batteries.
Lead-acid batteries have mature technology and relatively lower prices, especially the maintenance-free type, which is widely used due to their safety and simplicity. Lithium batteries, on the other hand, are a newer option—they’re lighter, have a longer cycle life, but come at a higher cost.
Different applications have very different requirements for UPS batteries. Making a random choice could result in backup time that doesn’t match your actual needs.
We can roughly divide the usage scenarios of UPS into two categories:
**Home and Office Use**: For devices like routers, computers, surveillance cameras, and access control systems. These devices have lower power demands and require UPS batteries that are plug-and-play, quiet, and provide sufficient backup time.
**Commercial and Industrial Use**: Includes medical equipment (e.g., ventilators, CT scanners), data centers, and industrial automation systems. These scenarios demand extremely high reliability in power switching speed and voltage stability.
For most home and office users, lead-acid batteries still hold clear advantages in terms of cost-effectiveness and safety.
Among lithium batteries, lithium iron phosphate (LiFePO4) batteries stand out with high energy density—their size and weight are only about one-third of lead-acid batteries, and they can achieve over 1,500 charge cycles. For example, ShanShuo Power’s ET Series Lithium UPS uses all-new LiFePO4 battery cells.
In terms of application suitability, high-density environments like data centers should prioritize lithium batteries, while regular office use can opt for lead-acid batteries.
