Types of Sealed Ups batteries include VRLA or sealed batteries and wet batteries or flooded batteries. These batteries are the best type to ensure an uninterrupted power supply because they require minimal maintenance, provide long-term protection for up to 20 years, or are less costly. Sealed Ups Battery has a shorter service life, but requires less maintenance. Wet batteries have a longer lifespan, but require more frequent maintenance.

　　Predictive maintenance and testing are essential for both types of batteries.

　　You should clean, repair, and replace components as needed.

　　You should always use the same type and brand of batteries to replace worn-out batteries. If aging is the cause of the failure, the best practice is to replace the array as soon as possible.

　　Sealed Ups Battery requires annual maintenance, while wet batteries require quarterly maintenance.

　　Typical battery maintenance includes measuring and recording temperature, humidity, and voltage readings.

　　Adding distilled water to the wet battery is essential for normal operation.

　　Investigate conditions that can cause battery failures, such as excessive cycling, lack of temperature control, poor charging, and environmental pollutants.
