That's good to know. Here are some of the readings with outside temp at -30F, lowest battery hold temp at 17F, and lowest voltage was 12.4v with the highest at 15.8

I'm all for modding. Not to be a debby downer but too many are all to quick to declare success.

Those voltage spikes would be of concern IMO and almost seem like impedance mismatches. 15.8V is considerable and not all car electronics will be okay with that over time.

While the Antigravity might work in a Porsche in mild climate (I'd actually consider one for my 911 where the battery doesn't sit in the engine bay), I'd really caution its use for 200-series in the hot Southwest region doing long trips or slow crawling.

If you look online, there are examples of overheated batts reaching thermal protection and switching off. Other applications have also shown melted and thermal runaway incidents.

Gotta ask - I don't see how taking on these risk is making the LC "better".
 
there is no "Coding" required for a Land Cruiser 200 series, nor does it have a BMS, old school alternator charging is all it does and it is setup for a Flooded wet cell.
 
Thanks @rlynch356 that's exactly the answer I was looking for and one less headache to deal with - battery registration. As to summer and traffic although it can get into the high 80s with 22 hours of daylight, one of the many reasons we live up here is that traffic (or crowds) are not a concern.

I’m not aware of any registration for the 200 regarding batteries.

I think the anti-theft system is coded, can’t think of any other part that is ecu tracked in this way. The key ids and TPMS ids, but that isn’t really what you meant.

Swap away, just know the charging profile is for a FLA.
