The batteries form the core of any UPS system. It can’t provide power in the event of an outage without them, but even batteries will need replacing over time. The expected life of most UPS batteries will be between 3-5 years but the life-span can be dramatically affected by environmental factors that can turn 5 years into much less. But with proper maintenance, it’s possible to keep your uninterruptible power supply battery life as optimal as possible! What can reduce the life of my UPS batteries?

Batteries in a UPS work best in a temperature range between 19-22 degrees Celsius. If the conditions are lower than this then the batteries will under-perform and likely sustain some damage. But equally, if the conditions pass above 22 degrees the batteries capacity will increase but their lifespan will get shorter.The prime benefit of the parallel string is that if a single battery fails, the UPS can still function (albeit at a diminished capacity) but when in series, a single dead cell will cause the entire string to inevitably fail. The best way to prevent this is to frequently test your batteries. Battery Testing

Keeping your battery temperatures within the optimum range is the best way to ensure their life-span is maximized. It’s estimated that for every 10°C above 25°C the battery life is halved – which means batteries operating at 35ºC will have their life expectancy halved and those running at 45ºC will only achieve 25% of their expected life. Which means a battery that was initially expected to last for 5 years will only last 18 months! In addition, if a single battery fails due to over-heating, this is likely to lead to a degeneration of the condition of the other batteries in the string. Protecting your sensitive equipment is incredibly important and an Uninterruptible Power Supply is the best method to do so. But then how do you protect your UPS? By looking after the batteries.
