'06 Battery Replacement

TheParadox66b · 06-05-2006, 06:13 PM

I have been looking around and saw some posts of replacing the aux battery in the 00 - 03's but nothing really after that?

has anyone changed an 06 battery for some higher Ah or CA/CCA? Can you do the miata battery "Mod" with an 06?

What are the dimentions on an 06' aux battery

Why do you need cold cranking amps in a car that doesn't require cold cranking? A deep cycle battery is more along the lines of what the Prius requires.

I can can see a use for a larger battery if you wanted to run the radio in the ACC position longer than you could with the original battery.

True, but cca wouldn't be what one would be looking for. That's a starter battery and they absolutely don't tolerate being drawn down, at least not if one is expecting a reasonable life from the battery. A higher amperage deep cycle would be the way to go for that.

Anyway, doesn't the charger work to recharge the 12v battery if acc mode is chosen? I don't know, I'm asking. If it does, then it's meaningless.

No. That's why in ACC mode, the car shuts itself off after 1 hr. I think someone here mentioned that the 12V would last in ACC mode with the radio cranked about 2-3 hours.

Yes, there was a discussion about using a Prius to go to a drive-in, where they use FM to send the audio. You could have the radio on (with the MFD off) or you could stay in the "Ready" mode.

want a good battery? smack down some bucks for an optima.

hobbit · 06-06-2006, 02:11 AM

yeah, but *which* optima, that will fit in the hole and present
the same "pencil posts" to the stock lugs? I was just looking into
this last night but couldn't quite determine which one might be
the closest match...

hob -

Please please please let me know which one you get and how close it comes if you replace, or how much you had to mod you car/battery area. thanks

You are absolutely correct, having a higher CCA gives me no advantage... but i do want something higher Ah Rating, which i guess i got my terms mixed up, i just kinda assumed higher cc/cca means higher Amp Hours.

I don't think the 12v aux batt gets recharged in ACC Mode, that would make the aux batt kinda silly, maybe toyota put it there as kinda a backup or something to jump the car on

???

optima does make 12v batteries- they were designed for hondas originally. they are group 51 and group 51R- don't recall which is the correct one. the only difference is that the + and - terminals are reversed on one of them.

the battery is small enough to fit into the area. it may be taller- and if that's the case the existing setup may not hold it. then you'd have to change the holddown bracket bar and maybe extend the post that it screws down to.
