I have a 2002 Chevy Suburban that was recently purchased. The battery seemed to have been drained over the freezing night. Thinking I found the solution; the light adapter for the trailer was not unplugged and will therefore stay on; I unplugged the adapter and attempted to jump the chevy with my nissan frontier. After numerous attempts the engine will still not turn over. The battery appears to gain a charge after about 5-10 minutes, sitting around 10-12 volts according to the guage. However, with one attempt to start the engine the battery again is drained to the point where windows barely move and dash lights are a faint glow. I am about to go out again and check the connections and that the electrolyte fluid in the battery is not frozen, but if that isn't the problem what is? I don't believe that it could be the alternator or the starter since it tries to turn over and seems to come so close but just drins too quickly. Would my best bet be to get a new battery?

Since you already have another vehicle to drive, my suggestion would be to get the battery charged up. If you have a battery charger just do it at home. If not, take it to the nearest Wal-Mart and get them to charge it. In the meantime, make sure all of the connections are clean. The battery as well as the connectors need to be clean. Wal-Mart can also do a load test on the battery at that time. The full charge on a good battery should be about 13 volts. It sounds to me as if your starter may be pulling too much juice to start, resulting in the battery going down too fast. I hope this is helpful.
