Advanced Battery Management (ABM) Like all UPSs, the Avaya UPS is equipped with a charger that charges the battery. Charger However, Avaya uses a unique charging technique that extends the life of the battery . . . Click to continue ê

3-Stage Charging System ABM uses a 3-stage charging system: Charger 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 ê

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

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 ê

When they test the battery they read both the charge of the battery as well as the trickle charge.
