If the power backup you’ve been relying on is underperforming, then yes, it likely needs a battery replacement. UPS batteries typically last up to 5 years, but it can be shorter depending on usage and frequency of power outages. Like most things, a UPS subjected to frequent use and abuse is likely to incur wear and tear more quickly than one that is rarely used. Because the length of time doesn’t always mean a new battery is needed, it’s important to know what other signs indicate a battery replacement.
Number of Years Since the Purchase Date
Of course, you start by considering how long it’s been since you purchased the UPS.
- If you’ve been using it for three or five years, one cause of an issue you’ve been experiencing might be the battery. A good practice is to replace the battery within this range.
- To be safe and ensure peak performance, make it a habit to replace the batteries within three to five years.
- Don’t wait for the batteries to go past their life-cycle expectancy. Otherwise, it’s going to fail during a critical power event.
Warning Lights or Sounds
Flashing lights or loud beeping usually indicate a problem with the UPS, most likely the battery.
- Depending on the system you have, you may get a mobile notification or a symbol might be displayed on a unit’s digital display.
- Make sure to have your UPS checked as soon as you hear a sharp beeping sound. Even when the battery is not the problem, consider its life cycle and replace it accordingly.
Reduced Runtime or Backup
You got a UPS to provide you with backup power; if you’re no longer getting a lot of it, then the battery may not hold a charge effectively.
- Sulphur crystals of lead-acid batteries may build up on the battery plates over time. When most of the plates are covered, the charge is significantly reduced. In a busy data centre, you don’t want to be worrying about power backup while trying to manage digital safety settings.
- Run diagnostics when possible. This is the quickest way to check any performance issues that need to be addressed, including battery life.
- At the slightest change of performance, test the UPS capacity. Power everything down and connect something else to the unit. If the charge drains a few minutes after you turn on a portable stereo, for example, then the battery’s health is compromised.
Look for Visual Indicators
Most lithium-ion batteries will show physical evidence of a problem. If your gaming rig cuts short your enjoyment of Unblocked Games 6x during an outage when it used to last longer, physically inspect the UPS. You may not need to pull it apart to know a batter replacement is in order.
Some of the signs to look for are:
- Bulging or swelling
- Overeating
- Fluid leaking
- Residue
- Foul or unusual odours
- Corroded terminals
Apart from reduced runtime and backup power, battery failure can also result in random shutdowns, which can be a real headache when you’re in the middle of an important task. The moment you notice performance and physical signs of battery problems, get a professional diagnosis and respond properly. If replacement is necessary, UPS Solutions carries a range of replacement batteries for different systems.
