Re: 6vdc Trojan T105 (225ah) Equalization

Float does nothing useful other than offset self-discharge.

2-3 day's rest ditto, except to check voltage.

Do the commissioning cycle(s) on the new set, then use normally but gently say 50+ cycles before load testing, long as you don't go past warranty cut off.

Or if you enjoy doing it you sick OCD do one asap before commissioning then one after the 50 cycles be amazed magic gain in capacity.

wrt the old set be prepared to scrap, swapping will get old fast.

Re: 6vdc Trojan T105 (225ah) Equalization

"Or if you enjoy doing it you sick OCD do one asap before commissioning then one after the 50 cycles be amazed magic gain in capacity."

Ok, so being new batteries and not exercised for 50 cycles, is another reason a near 50% discharge showed only 53 amps.

Additionally, while reviewing notes taken from Trojan documentation, they regard 12.1v as 50% disharged.

So the Link10 voltage inaccuracy of 0.18, taking the amp reading at 12.2 instead of 12.1v, the heat, and the fact they are new batteries without 50 cycles completed, are the reasons I did not see -112.5 amp on my Link10.

Is it better to take the battery down to near 50% during the initial 50 cycles rather than shallow discharges and then recharge of 30-40:amps?

Again overthinking.

During break in, after commissioning protocol, just use them as needed. Except try to be gentle in C rates. That's all.

And as accurate as possible means of guesstimating SoC should be primary, voltage becomes nearly irrelevant.

Load test for SoH.
