2.3 Battery life

The life expectancy of a Genesis battery depends on the

specific application. It is expressed in terms of either

cycles or years. While life in years is self-explanatory,

a cycle refers to a sequence in which a charged battery is

discharged and then charged back up. One complete

sequence constitutes one cycle. In general, if the battery

is to be discharged frequently, cycle life rather than

calendar life is more relevant. On the other hand, if the

battery is to be used primarily as power backup, calendar

life of the battery should be considered.

In situations where one is not quite sure whether the

application is cyclic or standby (float), the following

criteria may be used to determine the application

category:

If the average time on charge between two successive

discharges is thirty (30) days, the application may be

considered to be of a standby (float) nature.

The minimum time between two successive

discharges must not be less than fourteen (14) days.

If either of these two criteria is not satisfied, the

application should be considered cyclic.

2.2 Choosing the right Genesis

version

As mentioned before, the Genesis

pure lead-tin

battery is available in EP and XE versions.

The EP battery is adequate under most operating

conditions.

Special application situations such as high ambient

temperature or high shock and vibration require the

XE version.

Table 2.2.1 summarises the differences between the

two versions and is designed to help you choose the

right version for your application. In this table, the

differences are highlighted in red boldfaced.
