I'd say it tested bad. They told you based on the load test that
it was on the last 25% of it's life, which means it has reduced
capacity and they are *guessing* that's about how much life it has
left. You also know it's 4 years old. But it's your generator, house
and battery.

Fair enough.

If it were a critical application, I'd worry more. I can live without
power when it goes out (like very many people do). If I "really" want
to start the generator, I can "jump it" from my car.

So, it's not a mission critical situation if the battery doesn't
start the generator the next time the power goes out.
