Questions about this item

What does the 15.5 V rating mean when the battery is installed in a Dell Latitude 5410?

The 15.5 V rating is the nominal voltage the pack delivers to the Latitude 5410; the system regulates this internally to power its components.

How does the 4-cell layout affect the capacity ceiling compared with higher-cell packs?

Four cells limit the total watt-hour capacity, so run-time will be shorter than a 6-cell or 9-cell alternative in the same chassis.
