What type of battery is used in UPS power supply?

Lead-acid maintenance-free battery: It is a kind of battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a kind of battery of sulfuric acid solution. Cheap price, easy maintenance.

Deep-cycle maintenance-free batteries: Deep-cycle batteries have a large discharge depth, for example, when the battery is discharged to about 10V, deep-cycle batteries can be placed at a lower voltage. The battery needs to be used with a matching controller to perform well.

Colloidal Maintenance-Free Battery: High Sealing Battery. When the battery is charged and discharged, it has less acid overflow and water loss, and its service life is longer than that of ordinary batteries. It can be used in harsh environment.

Lithium iron phosphate maintenance-free battery: refers to lithium ion battery using lithium iron phosphate as cathode material. Lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials and lithium iron phosphate are the main cathode materials for lithium ion batteries. Among them, lithium cobalt oxide is the cathode material used in most lithium-ion batteries.

Because of the relatively high price of lithium iron phosphate batteries, they are not used by the public. Maintenance-free lead-acid batteries and Yuasa batteries are commonly used.
