When to Replace a Battery
Battery life is affected by the age of the battery, its operating temperature and the number of
discharge/charge cycles that it goes through over time. Industry surveys report that average
daily use (8 hours or less at nominal room temperature) equates to approximately 300-400
cycles per year. Batteries operating at this level of usage that are properly cared for can last as
long as two years or even longer. However, if the batteries are in constant use (24/7), subjected
to frequent temperature extremes or are subjected to complete discharging frequently they will
deteriorate more rapidly. Under these conditions, DRS recommends at least an annual
replacement.
To determine the age of the battery, check the lot number on the battery label (see Figure 92).
This number is the date (mm/yy) the battery was shipped from DRS.
