Secondary Battery

[Paulguy100]

I'll never use the Autostop function. If I remove the secondary battery and tape the leads off, would there ever be a problem? I've read posts about tying in the N1 and N2 terminals, I'm just not sure why.

I’m gonna watch this thread as I’m curious too. I have my ESS disabled via the Tazer so I’m curious as to why you are wanting to remove the battery.

Disabled or not, the auxiliary battery will still drain the main battery once the auxiliary goes bad.

Unless it's not connected

I'm gonna watch this thread until I figure out the N1 N2 jumper thing.

curious as well.. my ESS just stopped working a few months ago.. took me a few weeks to realize that it wasn't functioning, then i saw that there is a battery indicator light on the dash when i start the vehicle. can't say i miss the auto start/stop.. my head unit (heigh10) apparently also has the capability to keep the ESS disengaged, so i'll probably keep it off if/when i replace the aux battery.

i keep reading on here that the stock battery is junk, probably better off just buying a decent replacement. i've yet to see any adverse side-effects by having a dead aux. i've only got ~8k miles on the thing.

There are several existing threads on this forum covering this exact subject in great detail. Here's one:

Also, in brief the N1/N2 jumper fools the JL into thinking the Aux battery is still present after its been disconnected (by various different methods)

Did you get N1/N2 figured out yet?

No, it's in one of my bookmarked threads. I'll wait until it warms up outside.

Check my thread.
Anybody stuff a bigger battery in the factory location on a 3.0L yet?

IMO all any of us need is a battery with 4 posts. Find a suitable unit that will swap in with no mods and just delete the aux. battery. Put the leads from the aux. On the spare posts and you're home free.

I just searched through odyssey's other offerings and didn't see anything that was laid out in the correct orientation. 4 posts seems to be the ticket though.
