Check, or have someone check, the battery connections both at the battery and the other ends to make sure they are tightly connected. Check that that you or the other drivers are not leaving something on in your Envoy. Just prior to turning off the engine, turn everything off including the radio, interior lights, etc.

Once you're sure you have a good battery in it...Have someplace do a free diagnostic check on the battery, starter, and charging system. Some parts stores will do it to. When the battery is good and fully charged is when it will be easiest to find what else is going on.

Battery symbol light 1997 Chevy truck dash?

The battery symbol light indicates that, for whatever reason, the electrical system in the vehicle is not being supplied with the proper voltage. This is often caused by a malfunctioning battery or alternator. Since the battery is the easiest to remove and replace and is most prone to failure it is recommended that you have the battery checked. This can be done, usually for free, at any auto-parts store.
