Battery Load Testing

[JoeRaisin <joeraisin@xxxxxxxxxxx>]

When performing PM services, how you you guys load test sealed lead acid
batteries?

I'm seeing two schools of thought around here:

Some say to disconnect the AC from the panel and let it sit for one
minute, then check to ensure the battery has dropped less than 1 volt.

Some say to disconnect the battery from the panel check the voltage the
battery holds at, connect a 1 amp load for a minute, remove the load and
ensure the voltage has dropped less than 1 volt.

For the most part I am talking about household systems generally using
FA162's-168's or commercial situations using fire rated vista's or first
alerts.

Thoughts?
