Coming from a BMW and Mini background, I will say that the battery thing is annoying, but I have not seen it as a real problem.

Yes, it cost be a bit more, but I also bought the cars knowing the additional costs of ownership (just like the higher replacement costs with Brembo brakes, and tires on the track...), and based on how long they last vs my other vehicles, I am not sweating it too much.

The "battery registration" is there to match the charging to the age and type of battery, and in my experience, those with the feature lasted longer than in my other vehicles without it.

Given the option, I'd much rather do it myself - but it wasnt worth my spending the money on a programmer for something I did once over the life of ownership.

Call me frugal. The 21 RX350 17k mi at the dealer’s lot had a soh 67%. No pic. Charged it up with a PulseTech xc400 for 3hrs. It was 74%.










Plates were desulfated and eventually got to 95%
Not bad for a battery restoration. It dropped 0.63 mill-ohms.
I also used a Batteryminder 2012.
