Whilst not in the UK, battery trains have been used to replace DMUs in Japan. Here is some information from Wikipedia:-I agree. They could be used to test battery equipment but I can't see anyone signing up to widespread battery use until the conversion is proven given what has happened with 769s
From March 2014, a two-car battery electric multiple unit, the EV-E301 series with 1,500 V DC overhead wire and battery power capability, entered revenue-earning service on the 20 km (12 mi) long non-electrified Karasuyama Line.[33]
Since March 4, 2017, battery electric trains have completely replaced diesel multiple units on this route. There are four two-car sets in operation, each set equipped with a 190 kWh lithium-ion battery.[34]
The trains recharge their batteries at Karasuyama Station (the end of the line) via their pantographs, using a rigid conductor bar placed where the overhead wires would be, connected to the local electric grid. At the other end, at Hōshakuji, the Karasuyama Line meets the electrified Tohoku Main Line. The trains then continue over the electrified Tohoku Main Line to Utsunomiya, where passengers can change to Shinkansen high-speed trains.
Obviously that was a newly built train, but I can't see why similar technology couldn't be used in an older EMU.
