During his duties the woman commented on his strong arms, and led to him touching her nipple, he said.
He left the room after completing his duties, court documents say.
Batts later told police he had “made a mistake” but that no one had been hurt by his actions.
The victim had since died and her daughter wrote a statement in which she spoke of “a huge breach of trust and an assault on the dignity of a vulnerable and much-loved elderly person”.
“The family will never know exactly what happened; there will always be unanswered questions and concerns about any distress she may have suffered,” she said.
However, she did not want Batts to be jailed over the incident.
The fact the defendant had confessed to the crime gave the family hope he would seek the help he required to ensure he did not transgress again.
Judge Turner said the stance was “very generous”.
“Many people in the community will rightly feel appalled at your behaviour towards this victim,” he told Batts.
Counsel Anne Stevens KC said her client had lost his job following his disclosures and looked likely to lose the employment he had since attained.
“He worked in the care industry for a very long time and is sad to have lost that type of work, which he enjoyed and performed very well,” she said.
The molestation had been an isolated incident, she said.
The court heard Batts had no relevant previous convictions.
He had mental health issues characterised by anxiety and depression, but health professionals had not settled on a specific diagnosis.
Stevens said he had stopped taking medication shortly before the offence took place.
The judge, though, said there was no evidence before the court that established a causal link between Batts’ mental health issues and the sex crime he committed.
