Kstar UPS Interactive Power Supplies @ Matrix Warehouse Computers

The Kstar uninterruptible power supply (UPS) allows a computer to keep running for at least a short time when the primary power source is lost. Kstar UPS devices also provide protection from power surges. A UPS contains a battery that “kicks in” when the device senses a loss of power from the primary source.

When choosing a UPS, you should consider the lifespan of your UPS batteries. Because it is usually shorter than your UPS and you should replace the battery on time to avoid UPS failure.

UPS batteries (traditional sealed lead-acid batteries) tend to have either a 5-year or 10-year design life. Some may last for 10-15 years. Yet performance will significantly reduce overtime to a degree where it is not safe to use in a UPS system. So you should figure out its service life instead of design life.
