What are the commonly used batteries in UPS power applications? There are three types of batteries in UPS battery applications: including open-type liquid lead-acid batteries, maintenance-free batteries, and nickel-chromium batteries. The batteries currently equipped by UPS manufacturers are generally maintenance-free batteries. The advantages and disadvantages of the three types of batteries are mainly analyzed below: 1. Open-type lead-acid batteries: Advantages: less investment, longer life than maintenance-free batteries, and temperature The requirements are low. Disadvantages: maintenance is more complicated, a dedicated battery room is required, corrosive gas is exhausted, initial charging on site is required for 50-90 hours, and special maintenance is required. 2. Maintenance-free battery: Advantages: No need to add liquid and other maintenance, can be transported in a fully charged state, and no maintenance is required. Disadvantages: The battery will be damaged if it is not recharged in time, it is more sensitive to temperature, has a shorter life span, and is more expensive than lead-acid batteries. 3. Nickel-chromium batteries: Advantages: low maintenance requirements, long life, insensitive to temperature, and no harmful gas emissions. Disadvantages: The most expensive of the three batteries.
