If I may, what's a load test and how do you do it?
Would that indicate if the battery is dying or about to be dead?
Yes it would.
You need a load tester. It puts a load on the battery for several seconds and measures the voltage drop under load. I bought one at Harbor Freight on sale a few years ago. Less than 30 bucks if I remember right. I know, Harbor Freight but it's good enough for the amount I use it. At least it should tell me if I need to get a battery checked with a good quality tester.
The dealer does a load test on our Audi battery every time it goes in for service. Six years and still good but it is located under the cargo compartment floor where it isn't exposed to weather or engine heat.
