Those new batteries are sulphated and probably have one or more seriously

batteries, not some that have been sitting in a warehouse for 5 years

Absolutely NO NEW BATTERY will read under 13.5 volts, even with a 20A

I wouldn't worry about it if I were you. Larry's got a sulfation fetish of
sorts (and he can't even spell it correctly). This isn't the first time he's
attributed every reported low battery charge to sulfation. Places that sell
batteries often fail to give them a good initial first charge. Some are
stuck on stupid with the lame belief that lead acid batteries are 'dry
charged' and all one must do is add electrolyte and they have enough of a
charge to start up a motor where the generator will charge them the rest of
the way. This is wrong. Unless a battery is given a proper charging after
the electrolyte is added and allowed to soak into the plates and the level
re-established to the proper height to top off the charge it could end up
having a reduced capacity and or reduced working life. But, since your
battery(s) was put into service in November it is very doubtful it incurred
any harm considering you did finally top it up.
