Common Causes of an uncharged battery:
There are a few factors as to why your battery isn't charged or working properly. 80% of the time, the problem is connectivity. As batteries work on a constant basis, they produce acid. That acid comes up to the connectors slowly, but surely. It doesn't matter if you drive a Porsche or a Pontiac, batteries are batteries. They will inevitably leak acid at some point. Keeping the connectors clean is key.
If you are like most people, you don't clean them every month or two. You just turn on your car and expect it to work. However, when left alone for months at a time, that build up doesn't allow the metal in your cable that sends power to the car to make good contact with the battery connectors.
What to do to keep it clean:
First you'll need to loosen the screws or such that keep the cable connected to the battery. You can then use a simple tool with a metal brush inside that you can turn and spin on the connector. This will remove most acid and buildup. Follow that up with a wipe down with a rag. There is a certain type of red spray that is available at your local store to spray on the connector before you put the cables back on. This will prevent build up in the future.
Then put a battery lubricant on the connector as well and replace the cable onto the battery. If it still doesn't start, then 1 of 2 things probably happened.
1. The lack of connectivity did not allow the battery to charge properly, even though it is still good to hold a charge. It will need to be jump started and run for a while so it can re-charge.
2. It isn't able to hold a charge and the battery is bad. You can still get a jump start to get moving, but you'll need to go directly to an auto parts store or service shop to get a battery replacement. The next time you turn your car off, it is going to have the same issue and need another jump.
"I Replaced the Battery and I still get stranded"
If you are stuck and not able to start the car despite having a good battery, then the issue is probably a little deeper. You may have a bad alternator. This is the part that charges your battery as you drive. If it isn't working properly, you can have a brand new battery and after you have used up its core power, it won't recharge simply because there is nothing to charge it with.
This would require a tow to a service shop where they can replace the alternator or figure out if it is a different issue, like a bad starter etc.
