There are a few different factors that can contribute to the lifespan of a UPS battery. Some batteries can last much longer, while others can be useless in a very short time. It all depends on the conditions and how well you maintain your battery.
Factors that can affect the overall life of your UPS battery include:
- Operating temperature
- Discharge frequency
- Overcharge or undercharge
First, decide the best place to install UPS battery. When installing, it must be in a temperature-controlled environment. Do not place it near places that may be subject to moisture.
Regular maintenance of your UPS battery may be the best way to extend its life and get the most out of it.
One of the most important maintenance features to consider when caring for your battery is monitoring temperature rate. Regular checks and careful storage are also important. If the battery is not charged every 3 months, even if it has not been used, it will start to lose capacity. If you keep the habit of not charging it often enough, it will become unusable within a few months.
All batteries have a rated capacity determined under specified conditions. The rated capacity of a UPS battery is based on an ambient temperature. Operating the UPS under these conditions will maximize UPS life and result in optimum performance.
When a power outage occurs, the UPS automatically switches to battery to power the connected equipment. Once utility power is restored, the UPS battery will automatically recharge to prepare for the next power outage, a process known as a discharge cycle. The chemistry of a VRLA battery tells us that a battery can only undergo a certain number of discharge and recharge cycles before reaching the end of its useful life and it must be replaced after that time.
At the time of installation, a battery is at 100% of its rated capacity, however each subsequent discharge and recharge will slightly decrease a battery’s relative capacity. The length of the discharge cycle will determine how much of a battery’s capacity is reduced. Although cycling is a necessary part of inverter operation, knowing the frequency of cycles will help predict the life of an inverter.
Importance of UPS Battery
Use good quality wiring to avoid high resistance and increased stress on your UPS backup power supply. Low power devices keep the temperature of your UPS under control, extending the life of your device.
A UPS is an important part of our day-to-day life, either be at home or corporate sector. A UPS battery provides power for a short time during a power outage. This provides us time to save important work on PC and also protects our devices from possible damage.
The batteries in UPS are also known as Valve Regulated Lead Acid (VRLA) or Sealed Lead Acid (SLA) batteries.
Here are some tips and tricks to prolong the life of your UPS battery:
- Install your UPS unit in a cool and dry place
Your UPS should be installed in a place with a temperature not exceeding. Every rise in temperature reduces your battery’s life. Do not place your UPS near areas of high humidity.
- Regulate batteries once a year
Runtime regulation also extends the life of your UPS batteries. Once a year is enough to keep your batteries in good condition, as over-calibrating can significantly decrease battery life. UPS batteries are expensive, so avoid this mistake.
- Perform regular maintenance
Fully discharged batteries must be recharged to avoid damage. Pay attention to the discharge status of your batteries. Weekly battery changes, can cause charging problems and shorten the battery life.
