The lead-acid batteries typically used in a UPS are considered viable as long as they can maintain backup times of at least half that of new batteries. Virtually all other UPSs on the market today have batteries that are constantly trickle charged. Those batteries reach the end of their useful life in less than half the time of batteries that are charged using ABM. ABM uses a three-stage charging technique that not only doubles battery service life, but also optimizes battery recharge time and provides up to a 60-day advanced notification of the end of useful battery life.
