dual batteries stock

[jay]

i just got my navara and noticed ithad dual batteries stock. It is a brand new '09 model d22 and was just wondering why they have put dual batteries in it? I know why people do put dual batteries in. Juts wondering why nissan would put them in as stock. I can see no reason for the extra power of 2 batteries. BTW I'm not complaining just curious

Hey Jay,

I've no idea as to why they have gone up in amp hours but the 09's are also equipped with 90 amp alternators whereas the older D22's have 60amp.

When speaking to an auto sparky the other day, he said the wiring can be modded to make the second battery a proper back up, but I'm guessing this would void your warranty if anything melts or smokes for any reason.

Maybe they were working towards a most excellent static balance

Cheers,

DJ

another question. if i change my stereo will it void my warranty?

F.Y.I D40 has a 100amp alternator.

Fairly pointlless if both batteries are for starting and not isolated from each other.
Changing the stero won't effect the warranty on the diff for example. but if it causes the truck to catch on fire then you won't be covered.

The 08 D22 also has a 90 amp alt.

Take it to an auto elec and ask him to check the current draw of the horns?

I'd also get him to take a look inside the cells of your battery, and do the hydrometer test on it. Good chance that your alternator is also fighting the battery - depends what kind of shaking your battery's had (shaking could cause deposits to come loose and fall to the bottom of the battery which then shorts the cells).

I have no probs with mine.

Is that at idle though? Probably doesn't produce much juice at all at idle.

old tony, battery is only a year old and has only been roughish offroading twice.

pro nav, thats when driving normally that it dims, but also at idle.

will try look for the amp pull, but shouldnt be that much for a compressor that is 2/3 the size of a coke can.
