Not sure about the later ones, but the original “SRM” cranks and I think the first SRM installs on branded cranks required you to send them back to SRM for battery replacement. I seem to recall it would cost me roughly $400 Cdn for shipping and replacement. Like most head units, the PCx head unit battery was non-replaceable as well.
