Swapping batteries

[keitarosan]

Hello. I'm new in the forum but been a lurker for about 8 mos now.

Here's my question. I have a 2010 Nissan Rogue SL. My other car has the same battery size and specs as the stock battery on my Rogue. I'd like to buy a new and better battery for the Rogue and swap them out. How do I do this without resetting the stereo and the Homelink settings?

and the answer to your question: obd mem saver wire

so, this one won't work (link below) ? i'm kinda skeptical about it too. i was hoping something like this would work. it's a pain re-programming the garage door opener with homelink. the radio is not a pain to re-program it's the homelink that i'm trying to preserve the settings.

Get something like this:

sending power back through the cigarette lighter is questionable on some cars.
adding a booster pack(12volts) to a system already running 12volts - will double the voltage and could certainly fry something out.

put it this way: its easy to reprogram the radio & clock. its a inconvenience to reprogram the homelink/garage doors. BUT ITS A ABSOLUTE PAIN IN THE F-ING a** TO HAVE TO TOW THE CAR TO THE DEALER, AND FORK OUT HUNDREDS IF NOT THOUSANDS because the booster pack that was piggy backed to the car fried out the ecu/bcm, burned out fuses, fried out modules, etc.

i dont want to sound like a negative-nancy, but i do want to expose you to the real side of things. our cars have a TON of sensitive modules/computers/electronics that at the slightly power spike will fry out. there are so many "short-cuts" that can be done by do-it-yourselfers & mechanics, but they very often back fire and end up costing a ton more time & money to fix, than the initial problem to begin with. that is the biggest comparison between GOOD mechanics & BAD mechanics. the good ones, do whats supposed to be done, taking care to not risk anything, even it means more sweat & blood. the bad mechanics take short-cuts that risk the vehicle, and do so without due regard for the possible outcome.

whatever you choose to do: good luck, and report back.

Using a battery charger works as described in the link above but if you are worried about homelink- nothing happens even if the battery is disconnected as the homelink system has memory.

is that right??? it won't erase the homelink settings?? can somebody else confirm this? then that settles it... if that is true then i'll just replace the battery. the radio is very easy to re-program. the homelink / garage door opener is a pain though.

i had a feeling it didnt erase the settings. i think i did this in my maxima and it didnt reset the homelink.

thanks for the info guys. i decided not to risk it. i just bought a cheap battery for the other car and will sell it as we only need 1 car at this time. i'll leave the rogue alone just to be sure.
