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?

There's an extensive discussion of battery testing in a book on fire alarm
system operation from the NFPA. The book is "Operation of Fire Protection
Systems". Here's a link to an older release. You may find it helpful not
only about batteries but fire protective systems in general.

There are two possible reasons:
1. Your PC is FOS.
2. You are.

I use these and although they are a bit expensive, you get what you pay for.
