Chapter 12 Helpful information
8. Why are batteries disconnected on small, single-phase UPS units when they are
shipped?
This is so that they're in compliance with Department of Transportation (DOT) regulations.
9. Is it safe to transport sealed batteries?
VRLA batteries marked as "non-spillable" are safe and approved for all transportation
methods as long as the container is free of blemishes and local DOT regulations are followed.
10. How can I determine the age of a battery?
Batteries shipped on or after January 1, 2000 have a four-digit shipping code with the first two
digits as the year and the following two as the month in which the battery was shipped from
the factory. For example, a code of 1710 would be interpreted as 2017, October.
Extending battery service life
Lenovo UPS units uses a unique three-stage charging technique that significantly extends
battery service life and optimizes recharge time compared to traditional trickle charging. An
integrated battery management system tests and monitors battery health and remaining
lifetime and provides advance notification to guide preventive maintenance. Optional
temperature compensated charging monitors temperature changes and adjusts the charge rate
accordingly to properly charge the battery and greatly extend battery life. With remote
monitoring of the UPS and battery system, Lenovo is able to respond to alarms and real-time
battery data to avert potential battery problems.
Although batteries are sold with a variety of published life spans, the fact is, some demonstrate a
useful life of as little as three to five years. Lenovo UPS units employ battery charging technology that
significantly increases the life of UPS batteries.
