I was given a "spare" battery pack with BCM and MCM and I want to ID the components as to the year of manufacturer and upgrade. There was a recall that involved replacing the MCM and BCM.
Is there a way to tell if I have the upgraded versions or the older versions?
Is there a way to tell what the battery age is?

The 2004 Honda Technical Service Bulletin 04-028 says to replace the defective BCMs with part # K100-PHM-A01 (manual transmission), which makes 000-050 obsolete. The TSB also says to replace the MCM if the part number is any earlier than K000-PHM-060 (manual transmission).
Honda should have a record of doing any work based on the Vin #... if you can get the Vin # the battery came from.
if it was done by a non-Honda place... a little more difficult to track down.
The battery pack itself and each subpack have serial numbers which track it back to Panasonic.
Those would identify them... but I don't know how giving Panasonic would be with details.
Yeah, That's the problem. I haven't the foggiest idea what year car it came out of let alone the vin number; BUT, the condition is so good I wonder if maybe I should not even think of swapping out the BCM and MCM Apparently they didn't hurt the lifetime of THIS one. I may just leave them with the pack when I swap it out for mine. Then I can get a feel for what the differences might have been. I can always swap them out later if it looks like the changes were an improvement as the newer ones will be in the garage.

I just finished the recharge of the battery. I recorded the charge curve by hand, taking voltage measurements whenever I could remember and, just as Mike said, there is a slight downturn in the voltage when it reaches full charge.
I calculated the Ah I was putting in and it suggested that I would have put in 6.5Ah at 43.3 hours. Sometime between 41 and 44 hours the voltage turned down by 0.2 volts. Right on cue! I plan on continuing the 150ma charge for another 4 hours and then shutting it down for a 4 to 6 hour rest and begin the discharge cycle again and see where this got me. Its looking pretty good though/ The peak voltage was 172.5 Volts.
I noticed there is a "Charge monitor" function on the CBA-II and I am wondering if I could use that on a pair of sub packs to detect that voltage drop and shut off the charger. I will have to check out that possibility.

yes you can... you set the current to 0 and click start it will record / log the voltage over time graph... and you can label it with the current rage you are charging it at... but , if you are charging the whole 120 cell battery pack at once... you would have to only connect the CBA over a few of the subpacks, or just one... keep in mind that even if the ones you are watching with the CBA are done the others in the battery pack might need a bit more to finish off.
