Batteries
Batteries are the most critical component in the reliability of any UPS, but they face three fundamental challenges
- All batteries need charging, but extended charging significantly shortens battery life. Most batteries are charged via a trickle charging process (a constant voltage feeding a low current to the battery). This method dries the electrolyte and corrodes the plates, reducing potential life by up to 50%.
- Batteries take time to recharge – users can’t wait. During prolonged power outages, the UPS batteries will discharge and not recharge until the power returns. When there is subsequent power failure before the batteries recharge, the computer will not have full back up time. Overly rapid charging can cause premature battery failure, so the trick is to charge at the fastest rate that is safe for the battery.
- All batteries will eventually fail. The question isn’t “Will it happen?” but “When will it happen?” Because UPS batteries are valve-regulated sealed lead acid, there has been no practical way to provide the user with any meaningful advance notice that batteries need to be replaced. In the past, the only way to know when the batteries are dead is when the power fails and takes your computer down with it. Until now, typical UPS batteries have required replacement every two to three years.
Powerware’s exclusive, patented advanced battery management (ABM™) technology solves these UPS battery problems. It doubles the life of the UPS batteries, provides the fastest safe recharge time, and provides reliable advanced notice when the batteries need replacement. By doubling battery life and virtually eliminating this major cause of supply load crashes, Powerware is able to offer the industry’s longest and most inclusive warranties on all of its products that incorporate ABM™. No other manufacturer can make this statement.
