    Thank you for your help. I did take it and have it checked and the battery and alternator seem to be working properly. I am planning to take it to the shop today for a diagnostic, but just wanted to have an idea what I might be up against. :) Again, I appreciate you taking time to help me. Have a wonderful day.

If your battery isn't charging it is either because your alternator isn't putting out enough voltage or the battery has gone bad. With the engine running, check the voltage on the battery terminals. It should read 14.6, or a little lower, but definitely higher than 13. If the voltage is too low the problem is the alternator. If the voltage is reading over 14, the battery needs to be replaced. Are you certain the battery is not charging, or could it be that the battery is being drained overnight?

Look at both of your battery cables to see if there is any built up corrision around the post. Next, check to see if your battery is charged and if it will hold a charge with a battery recharger

Hi, I have a 2007 Chevy suburban that is extracting voltage while it sits causing our vehicle not to start and buying new batteries every 1.5 years. what could be causing the battery to extract voltage...


Fit an extra battery on the driver side its got a tray fitted already,just fit and run an earth lead and a positive lead.this will cure your problem.There is such a lot of electrics on the suburban that the battery ic drained and charged too often,its like your cell phone when you get it new it lasts for days and after a year it has to be charged every day.Hope this helps.

Battery light on, battery ok


How long has the light been on? Although the battery is ok, it most likely means it is not charging. Take the suburban to a parts store for a free check of the system. They should be able to determine if the alternator not charging.

Sounds like a bad altnator. if the alt. is working propperly it will run the burb. with out the battery installed. With that though, it possiably could of damaged the batt. enough to the point of replacement as well.
