Chapter 4 Battery Care and Maintenance
The float life of a cell is cut in half for roughly every 8°C (14.4°F) rise in ambient
temperature. The example below shows the relationship between ambient temperature and
float life for batteries that have a float life of ten years at 25°C (77°F).
A ten year battery lasts for five years at 33°C (91.4°F) and only 2½ years at 41°C
(105.8°F).
Preventative Maintenance
Itron recommends a preventative maintenance cycle of a two-year replacement in extreme
environments (average temperatures greater than 110°F/44°C), or five years in non-
extreme environments (average temperatures less than 90°F/31°C).
Replacing the Integrated Battery
The following procedure describes the integrated battery replacement after the equipment
is installed in the field.
Warning There is a risk of explosion if the battery is replaced by an incorrect type.
Always replace with Itron part number BAT-0045-001.
