Has anybody ever heard of a Battery Backup" system whereby there are two (2) batteries in your car and if one dies the other takes over thereby not leaving you stranded. Any thing remotely similar to this??

Dave Holmes

Haven't heard of a battery backup for cars. But you can get a booster pack to put in your trunk for if you get stranded. They're about $80 for a cheap one, and the price goes up from there. I'd get one with the DC outlets to power other things, too. From personal experiences, I can say that they will jump a Maxima!

I had a camperized van that I installed one of those in. It was mainly for running all the accessories in the camper but would kick in if the main battery failed. Its just a solenoid and a relay that switches over if the voltage drops.

The 4th generation Max's have a "battery saver" for any accessories left on. It's built in the BCM (body control module). If the voltage happens to fall below a certain value, the car actually turns off the accessory, such as the lights.

I had read about the battery saver feature. Unfortunately, it didn't work on my '96 GXE (RIP). I'm not entirely sure if it even had it or not. I left my lights on while at work and my car was so dead that my keyless entry didn't even work. That car's "annoying" ding when the lights were left on didn't work. But after that, I've grown fond of that ding (maybe not fond, but definitely tolerant)!

Nope. Not true.

the car will turn the lights off say if you leave the door open, the interior lights will shut off after awhile, it saves energy for the batter but it doesnt happen because the battery is low on juice

this sounds more like a mod for an RV or Motor-Home!!
