Hummer H3 Battery Change. Plus: Avoid losing all your settings and/or triggering the immobilizer! 

Best hummer battery change video I’ve seen. Thank you

Great vid. Good audio. Thank you for NOT playing annoying music!!!!

I know this is an old video but for those of you watching recently a 9-volt battery plugged in to your cigarette lighter will keep the memory of the vehicle you don't have to go buy a trickle charger so if you're on a budget you can hook a 9-volt battery to a cord with a cigarette lighter plug on the end of it you plug that in then after you hook your battery up then you remove the attachment from your cigarette lighter and you're all set😊😊

Nice. Thanks. My battery just died due to negative temperatures. I dont have a garage so ill be out in the cold trying to do this. Also i dont have a trickle charger.

Great Video

thanks for this!

Do you know what fuse is the one that goes out if you connect the battery backwards? My husband accidentally reversed the cables

My door locks don't all work when I hit the power door unlock button, So I read that it is safe to touch the cables together in order to make electric door locks work again. Is it safe to do or will it trigger the immobilizer?

Where to you plug the trickle charger in at while you are changing the battery?

Hello sir, I have a Hummer H3 year 2007 my client had changed the battery, and the vehicule is no longer starting and when Iscan I get the error code B2928

You say you have a Hummer H3X.... sorry but that's just a regular hummer H3. An H3X has exclusive extra chrome parts on the exterior, specific interior trim, and a larger wheel size (with chrome rims).

I changed the battery and now it don't start why

Thanks for this upload Cliff! Thumbs up and a sub from me... Stay safe... Rico

In case of the H3, you need not worry about disabling the vehicle by removing the battery, especially if you do it right! - (negative) lug needs to come off first, then the + (positive). Reverse order when installing the battery = + on first, - on last. Nothing needs resetting UNLESS you do a complete drain / reset by touching the + and - harness cables together with battery removed. That is why SUPPLYING POWER TO THE WIRING OF THE VEHICLE VIA YOUR TRICKLE CHARGER IS A BAD AND DANGEROUS IDEA!
