UPS battery provides DC power supply for electric equipment, which requires long working life.  UPS Battery Backup protect your equipment against blackouts, brownouts and power surge that can damage equipment so make sure your battery is in peak condition.It is well known that the most common reason for load loss is due to battery failure.So UPS battery plays an important role in the UPS system, it’s crucial to take care of your battery.Proper battery maintenance can not only greatly reduce the risk of costly downtime, it can also extend the overall service life of your battery.

The Vulnerability of UPS Batteriesuninterruptible power supply

A battery is an electro-chemical device that is susceptible to a variety of external factors. Keeping your battery in suboptimal conditions can lead to premature failure, taking down your modular UPS system  with it.

Some of these poor conditions include:

1.High Temperatures – The rated capacity of every battery is based on an ambient temperature of 77°F (25°C). Generally, every 15°F above this recommended temperature will reduce the battery’s expected life by 50 percent.

2.Poor Ventilation – Batteries must be stored in a clean, well ventilated environment. Dusty, dirty, caustic or otherwise poor conditions can decrease a battery’s lifespan.

3.Improper Float Voltages – Undercharging or low voltage can create sulfate crystals on a battery’s plates. Eventually, these crystals will harden and reduce the available capacity of the battery.

Conversely, overcharging with too high a float voltage can cause excessive hydrogen and oxygen gasses, leading to internal dry out and possibly thermal runaway.

4.Loose Terminal or Intercell Connections – If your battery’s intercell connections are not firmly in place, its lifespan can be decreased. The only way to detect this is by testing the torque of the battery connections during a maintenance check.

5.Damaged Casings – Similar to the intercell connections, damaged casings due to poor storage or other issues can cause premature battery failure.

6.Several risks – to your facility and personal safety – arise when a battery is not properly tested or proactively replaced. Lack of proper preventative battery maintenance can eventually lead to fires, causing extensive damage to the UPS system as well as to the facility in which it resides.

With so much at stake, the costs associated with lost data or damage to critical equipment can be quite high. That’s why we recommend scheduling a maintenance check on your online UPS twice annually to sustain your battery’s longevity.

Check Your Battery

The primary objective of battery maintenance is to ensure that the battery system is capable of protecting critical loads when the need arises. Effective maintenance must be regular, comprehensive and consistent. Regular inspections include:

1.Visual Inspection – To identify any cracks, leaks or swelling of your battery

2. Inspect and Clean Terminal Connections – To ensure connections are strong and re-torque if necessary as well as check for corrosion

3.Taking Measurements – Includes measuring voltage, resistance and impedance to identify an internal or hidden issues

4.Temperature Checks – To ensure battery is not overheating

5.Capacity Testing – to identify any potential performance-related issues

All UPS batteries have a limited service life. However, battery life expectancy can vary greatly due to environmental conditions, number of discharge cycles and UPS maintenance.

It’s important to pay attention to UPS maintenance. Like the batteries that power your high-quality UPS, purpose-built uninterruptible power supply (UPS) power today’s mission-critical infrastructures. Life expectancy can vary greatly, depending on factors such as whether or not you proactively perform routine maintenance.
