Is it worth calibrating my batteries now it's warmer?

Back in the cold of November I update the firmware to 3022 on my two 9.5Kw batteries and the primary (older by a year) calibration capacity went down from 192 to 183Ah whilst the secondary stayed at 192Ah. I mentioned this to the GE engineer that visited to sort out an issue before their demise and he said that the loss was probably due to the temperature at the time. That sounds a bit sceptical to me, so has anyone real experience of calibrating the batteries now the temperature is a lot warmer or is this a load of bunkham 🤔

And would it be tempting fait to calibrate now GE have gone?

I calibrated my 9.5 on 3rd April. Capacity went from 167Ah to 163Ah. Mine is indoors so temperature not an issue.

I had to calibrate mine in April when a new inverter arrived 4 days after GE's demise, tried to no calibarte but the battery having lain idle for 3 months was confused, and the new inverter charged it to full and said 128Ah (down from 200Ah) as the battery said empty when it was over 50% in reality, so only counted 128Ah.

I did a calibrate, but only at 2.5kWh charge rate (I assume the calibrate did that) and it upped it to 192Ah, down 8Ah on exactly 2 years earlier when it was prev calibrated.

I'm not going to bother again for a while as it's still over 'spec' and I think it will just go down further.

I am getting regular over voltage messages in Ribikcubes app, but assume this is 3022 doing its self calibration.
