2005 Chevy Suburban Won’t Start	Sign In

All of a sudden the suburban wouldn’t start. Auto door locks wouldn’t work, engine wouldn’t even tuen over. Battery is a two battery and I’ve had it over two years.

Tried to charge battery on pro logic battery charger using 20v rate. Do you know what rate I should be charging at?

It said it was 67% charged. I need to turn in now due to work, do I disconnected the charger and tried to start the truck and it made a strange cliving noise and it the CD player started making a weird noise. Truck still won’t start.

I will try to charge to 100% tomorrow, besides that what do you suggest?

Quoting you: ">Battery is a two battery and I’ve had it over two years. <"
Did you mean has 2 (two) batteries or what by that? I'm going on this is one.

So far it seems you have zero response from any battery first test for voltage at the battery* at the posts and again at the eyelets is what connects to the vehicle NOT the post/bolt there.

Best: Take it out and get it charged OUT of vehicle. Do yourself a favor and this exact body primary battery is on driver's side POSITIVE post is real close to metal so disconnect NEGATIVE side first and on last is a standard for all anyway.

Get it charged and checked 20V whatever you have if really able to put out 20V and does isn't right. Put back a known good one then testing will mean something,

I hope you meant 20 amp and not 20v. You should be using a 12v charger.

You need to disconnect the batteries to charge and test them individually.

20 what as you asked HT. I can't think of 20Volt as some norm for much of anything. In series you get 24V (system) but not this thing? Lost. Did this all of a sudden from working so that's what needs to be found - why?
