Table 7 OPM battery rotation and test cycle

For each battery string pair, the rotation cycle provides a charge cycle one time

in a one-week interval. A test-and-charge cycle occurs one time in a four-week

interval. This cycle occurs for a different battery string pair each week. This

action occurs to test all pairs one time in a four-week interval. Less than four

battery strings can contain datafill for an OPM. If this condition occurs,

battery rotation activity does not occur during periods that are reserved. These

periods are reserved for the strings not datafilled.

Test-and-charge cycle description

The test-and-charge cycle detects battery strings that fail to hold enough

charge and require replacement.
