Battery Load Test

NOTE: Load testing requires use of battery side terminal adapters to insure good connections.

Perform battery load test as follows:

  1. Connect a voltmeter and a battery load tester across the battery terminals.
  2. Apply 300 ampere load for 15 seconds to remove surface charge from the battery. Remove load.
  3. Wait 15 seconds to let battery recover and apply specified test load of 380 amps. Read voltage after 15 seconds, then remove load.
  4. If voltage does not drop below the minimum listed, the battery is good and should be returned to service. See Fig 1 . The battery temperature must be estimated by feel and by the temperature the battery has been exposed to for the preceding few hours.
