Maynard, the son of former England batsman Matthew Maynard, was stopped by police on suspicion of drink driving near Wimbledon Park Underground station at 4am on June 18.
The ex-Glamorgan batsman was later the same night found electrocuted after stepping on a live rail before being struck by a tube train on the District line.
Batty, who took over as acting captain from Rory Hamilton-Brown after Maynard's death, said: "In some respects it (the inquest) drags a lot of bad memories up but also good memories as well because we don't want to forget Tom.
"But it is for a lot of people a final bit of closure so it can be finally goodbye and we can remember Tom as we want to, as a wonderful young man."
Former England spinner Batty admits the Surrey dressing room found it hard to cope and deal with Maynard's death. Wicketkeeper Steven Davies admitted earlier this month that he suffered from depression as a result of events last season.
Batty said: "I've never witnessed anything like it in my career. It was absolutely horrendous. It almost makes cricket secondary to everything else which is going on.
"The game took our mind off the horrible events and if you could put a smile on your face, being out there playing cricket, knowing Tom loved it, was a bit of comfort to people at times.
"But I've never witnessed half the team coming in and on a daily basis there would be people in tears in the corner. It was not a pleasant situation by any stretch."
Batty will accompany Jade Dernbach, who has just returned from England's tour of New Zealand, to the inquest.
He said: "I've spoken to Jade quite a bit and am going with him to give him support.
"I can only imagine what those guys (Dernbach and Hamilton-Brown) are thinking and going through.
"It is dredging up a lot of memories at a time when people want to forget. You never want to forget Tom but the horrible circumstances you want to forget."
