Battery Removal

[fire105]

Hey guys

Its starting to get cooler around my parts and I noticed the Yukon was having a weak start. I looked under the hood and I have some corrosion on the neg battery terminal which is probably the problem.

I was told by a person that you should not remove the battery terminals cause these vehicles have so much electronics that its bad and can mess things up if its without power. They suggested that when you need a new battery, to have the dealership replace it cause they can keep it under constant power when swapping out a battery.

This seemed a little fishy and I just wanted to double check before I pull the wires off to clean off the terminals. Am I ok to remove the battery for 10-15 minutes to do this? By the way, its an 08 Yukon Denali XL.

Thanks

You're fine to remove the wires. No worries

what they are talking about is using a memory saver on the car so you dont lose your radio presets , the time , and other memory functions . heres a link http://www.amazon.com/SOLAR-ESA30-Memory-Saver-Connector/dp/B002BHX1X8/ref=pd_sim_sbs_auto_6 to one if your interested in buying one . you connect them to your obd2 port and the other end to a power source. if that isnt important to you just swap out the battery and your set .
