All the dealers I have experience with only fill the battery with acid and perform the initial charge when the bike is sold. I would hope this wasn't done when the bike was received in to inventory as opposed to when it was sold so that the 4 years sitting time shouldn't be an issue. The Honda 3 year warranty starts on the date of sale so I would assume that he would get a pro-rated warranty replacement if the battery is defective.Likely it became deeply discharged before it sold in 2016... 4 years is a long time.
