Second battery location: OEM battery box worth it?

OK, in my world "every other vehicle I've owned".....meant you at some point you had a domestic (my bad if you didn't - clearly you didn't have most Audis or any BMW as they generally ditch the batt under the seat or in the trunk).
If you had a ton of Mazdas or VW's, my sincere apologies. Esp if they were VW's.

You bizarrely assumed that I had only owned domestic vehicles, and now you're saying that I have to have owned some arbitrary number of foreign vehicles in order for your assumption to have been wrong? What's the point of even bringing up domestic? It's a circular argument. "The Toyota battery box is the best solution because it's on a Toyota and it's not domestic and domestic doesn't doesn't use a similar design because domestic is bad." I don't understand why you would even bring that up.

You formed an opinion based on "every other vehicle I've owned" - but in another post cite the 70, so you wandered some there.

70 series or 100 series, who cares? I mentioned the 100 in the very first post. And again, what opinion have I formed??? I'm looking for information and all I'm getting out of you is cattiness, insults, and circular reasoning.

As for me being rude or dismissive, you used the phrase " ..., and those batteries lasted plenty long." --- I'd call that a 'good enough mentality', it worked long enough for you to state "LASTED PLENTY LONG".

Only if you choose to project that onto my words. Here's an alternative interpretation for you: I have seen no sign of a traditional battery tray leading to premature death of a battery, and I've seen no evidence of corrosion caused by said batteries.

I'm sorry, you win, best of luck on future projects.

And there's the problem: you think this is about winning. For me, this is about seeking objective data.

The box design with the hood and cable gaskets prevent heat shortening battery life, no brainer IMO.

Batteries in hot climates/environments always have a shorter life, and failure tends to be perfect one day and totally dead the next. Next to OBD warning lights, sudden battery failure represents the majority of my call outs.

Before installing my second battery in the OEM right side box.. I thought long and hard about the reason to install it in the standard manner. After the install and now 6k miles later.. all of the objective ideas put forth in this thread definitely hold true. To prove to myself one of the main technical reasons.. heat was truly a factor. With an IR thermometer I measured the difference in heat between the auxiliary battery and all areas the engine compartment. This was done this past Tuesday when it was warm here. The ambient air temp was 88 and I had driven for approximately 45 minutes.

Aux battery = 97 degrees
Air cleaner = 120 degrees
Exhaust side of firewall midway between the engine and fender = 138 degrees
Firewall more towards the exhaust = 148 degrees
Intake side of firewall = 105 degrees

One last thing worth thinking about and then I am bowing out. Should your battery ever explode for whatever reason and it still happens in todays world no matter that components exist today with newer tech.. it could be very ugly and very damaging. The OEM battery box could very well contain some of the damage within its corrosion resistant space.

This is good data.

@gummycarbs -

I wasn't being rude before (and am really not now, I don't know you to put that kind of effort into you).

I was simply bowing out with that final statement ('you win' just fit), like when the GF says her catchphase of "peace, sh!t, ***!" whenever she knows she's cornered in a water fight, or she pulls a prank and the payback is right in front of her.

'Best of luck on future projects' is a line from like Office Space, or Napoleon Dynamite - I flat had no interest in catering to you in whatever manner you are too lazy to pursue knowledge yourself (thank @zonker for doing the legwork for you, seriously, you should say 'thank you' to him).

So for the last time-

Peace, Sh!t, ***, I'm sorry, you win, best of luck on future projects.
