Majorumbra: Excesive heat and cold over a period of time can "kill" a battery too. Most batteries are only good for 5 years. If you have one that is 5 plus years old, time to go get it checked. You may need a new one.

Not checking the water level. (electrolytes, plus the lead/acid, and water make a battery keep a charge. In most car batteries.) Some batteries are "maintenance free" or "sealed" batteries. This type you just have to replace with a new one.
