If a battery load test is performed at room temperature, the final voltage should be:

Under a load test, you’re assessing how well the battery can maintain voltage when a heavy current is drawn, which reflects its internal resistance and remaining capacity. At room temperature, a healthy 12‑V lead‑acid battery should not fall below about 9.6 volts under the specified load. This threshold indicates the battery can deliver enough cranking current. If the voltage ends up lower than 9.6 V, it signals too much internal resistance or insufficient capacity, meaning the battery is failing. Therefore, the expected result is final voltage above 9.6 V under load. In practice, good batteries often read somewhat higher, around 10 V or more, and temperature can influence the reading—warmer temperatures help, colder temperatures hurt.
