. We get 20 years out of our batteries. Most are resistance checked, it is more expensive due to frequency than load testing.
I talked to the guy in charge of it, as I said if a battery is getting weak,and you load test it, you will may not get any more life.
One part of the company load tests every 5 years, cheaper due to frequency of resistance test.
Back to IEEE they have a formula for over 77f the battery is degraded. This upset some.
Some people here load test because it is all they know how to do.
if you read the article it does want you to limit testing, because it is destructive. They have just come up with a compromise for reliability vs shortening life.

But I do know it isn’t motorcycle batteries, which is what this discussion is about.
Once a year load testing isn’t going to make a bit of difference.
You know that already.
Time to move on.

In a cool climate like mine why damage the battery under 5 or 6 years. And then if you do it at the point where the battery is older, you will end up needing a new battery.
I just don't see the point in load testing a battery that is performing fine.
I realize at 7 years my battery might not pass a load test, but is working fine. I also realize when they hit 7 years need to start thinking about replacing.
But on these threads here when there is an electric problem first thing they do is load test, rather use any test practices or logic.
A shop might do that because they don't care about your battery, not their money and many mechanics don't understand electrical
As the article states, limit your load testing
Maybe my off road vehicles that go remote areas might be good to load test, or just replace. Though I have elected to carry jump pack. Hopefully charged.

Use the starter to load test the battery. Charge it up to at least 12.65 volts. Crank it over with the starter with a volt meter attached to the battery terminals. If the voltage drops below 9.6 volts, the battery needs to be replaced. No need for a fancy load tester.
