Checking the logs on my other two batteries, these (unlike the failed one) show an increasing number of Minor Deviations and some Major Deviations, but both still show 97% - 98% Battery life, good health etc. Should I be worried about these?

I've subscribed to Airdata and checked my logs but struggling to see any trend from the previous flights which would have warned me of the impending doom for that battery. Battery life is showing as 98%, Health looks okay, Minutes per battery is declining slowly with one flight that looks...

Okay thanks, when you say "If you also add in a regular monitoring of the total capacity, how cell deviations behave & how the flight times holds up ... all over time through out all flights with the battery you will be able to see when the battery will start to misbehave & can take it of flight...

Is there anything I can do to test batteries before a flight?

Looking back at the previous flight that was actually 7min 15secs rather than my guess of 5mins, the battery level started at 95% and gradually dropped to 66% at the end of that flight, can upload the logs from that flight as well if it helps, but doubt it will.
