bruce starts doing vigilante work at age 18, but doesn't go by 'batman' and have all of his cool tech until age 23
read more about my batman year zero & one here
bruce acts as batman until roughly age 63, giving him a grand total of 40 years working as batman
at age 60, however, he trades his regular suit for a more well armored mech suit, kinda like iron man's suit
63 through age 70 he operates the batdroid, a fully robotic version of batman // art credit
altough dick has taken on the batman mantle in times of crisis, the official new batman, a batman that was seen as early as bruce's mid 50s was both cassandra cain and tim wayne
cass and tim share the mantle, although cass becomes the main batman
the new batman primarily has spoiler and/or red robin as their main backup/support
The Batdroid.
