Sorting out the Ioniq's 12V battery
Like most EVs, the Ioniq Electric still runs a small 12V lead-acid battery alongside the main traction pack, quietly keeping the low-voltage systems alive. Mine finally gave up, so a replacement was overdue.
The swap itself was straightforward, but reconnecting it threw up a couple of quirks I wasn’t expecting. Regenerative braking reset back to its default level, rather than remembering the setting I’d left it on. Not a big deal, just a case of dialling it back in from the paddle shifters.
