The Weakest Link The weakest link of any UPS is the battery. It is the component that is most likely to fail. How the UPS manages the batteries is the key to extending their service life and increasing UPS reliability. Let’s see how Powerware does it... Click to continue 

ABM Charger Like other UPSs, the Powerware UPS is equipped with a charger that charges the battery. However, Powerware uses a unique charging technique that extends the life of the battery... Click to continue 

3-Stage Charging System Charger ABM uses a 3-stage charging system: First, the battery is quickly charged to 90% to make sure the UPS is prepared for the next power outage. Second, ABM finishes charging the battery with a more moderate float charge. Click to continue 

Turning the Charger Off Third, ABM turns the charger off. This prevents the batteries from being overcharged. Charger Click to continue 

Competitive Models Charger Competitive UPSs constantly trickle charge their batteries even after they are fully charged. This constant charging dries out the electrolyte and damages the batteries. As a result, the batteries in competitive UPSs don’t last nearly as long as Powerware’s. Help! Click to continue 

The Result? The service life of the batteries is doubled so you won’t have to replace them as often as you would with competitive models. Click to continue 

Battery Replacement While ABM significantly increases battery service life, it can’t prevent inevitable battery failure. Powerware doesn’t want you to take chances so ABM gives you advanced warning of the end of useful battery life... Click to continue 

Testing the Battery Because ABM turns off the battery charger, it is able to conduct an accurate test of the battery. Competitive models don’t turn off the charger. When they test the battery they read both the charge of the battery as well as the trickle charge. Charger Tests only the true battery capacity Tests the battery, but also reads the incoming charge ABM Charger Click to continue 
