Most of the ones run here don’t have batteries. It is running on wires only - with battery trolley bus you need bit different wires so you can put the “antenna” up and down when needed. And since the network was built in 50s it didn’t made sense to buy the partial ones until few years ago.
Keeping that in mind: would a good solution not be to have electric busses with batteries, which also have the umbilicle on a spring loaded or electronically actuated system to raise it to connect to the wires? This would allow said wires which would normally connect a trolley system to be placed along main strips while still allowed busses to travel along lesser used streets. The mobility of busses with the power system of trolleys to ensure they don’t have to stop to recharge or refuel, they can just connect on the main strip and keep their battery banks full.
I’d even say with something like this a supercapacitor bank to quickly charge those to 100% on connection then allow those to charge the batteries. This would help to reduce charge cycles on the battery and help to keep the batteries in a constant charge or constant discharge state instead of having every bump in the road disconnect the batteries from the grid.

Trains. Believe it or not. Boston still uses deisel commuter trains, including one “deisel under the wire” on the electrified Amtrak line. Everyone has been pushing to electrify but it’s expensive. Their solution is battery trains. They can run them on battery now, while tAking power from catenary as it’s built. Seems like a huge waste of money, but I guess you have to transition somehow
Isn’t a trolley bus just an electric bus with a “antenna” on top to charge its battery from an overhead cable?

BEV busses need much larger batteries, while trolley busses can get away with a very small battery
Yes, and they’re much cheaper and last longer, since they don’t need big batteries
