I raced with SCR 1400's in 92 for sure, perhaps also in 91. Before that were only SCR 1200s. SCE's in 1700-1800? They were around at the same time as the SCR 1400 but no one in 2WD used the SCE's. Some 4WD's did especially modifieds that couldn't make race time on SCRs. The SCR's could discharge at more amps and were the better battery. So if you could make the time on those that's what you ran. I have two packs of 1400s, and about 4 or 5 1200s and they all still work today which is amazing.

Maybe not quite as well as they used to but they do work quite well. I don't know anything about what happened after that as the nitro cars/truck came out and they caused the death of 95% of the clubs in Australia including all the ones I raced at.
