Dead Car Batteries
This campground has no grid power. Some people bring generators. Others use solar panels. A few use a combination of both. For quite a few people they just use the electricity from their cars.
A lot of people don't realize that car batteries are a poor choice to power things. Car batteries have one job, to start a car engine. The are designed to give a quick burst of power to turn the engine over. Once the engine is running, the battery is quickly charged up again. Batteries designed to start vehicles have thin plates. Batteries designed to power things, like trolling motor batteries, have thicker plates. They are designed to discharge smaller amounts of power over a longer period of time.
The woman camping across from me left the hatch up on her van all night. The hatch light, over time, killed the battery stone cold dead. The park workers are used to jumping cars, as people kill their starting batteries all the time in this park. He was unable to start her car with his jumper.
I carry a 700 amp jumper battery and that usually starts up just about anything. It was fully charged, but couldn't do the job. The addition of one of my big deep discharge batteries was able to do the trick. My guess is that the battery in her car is on its last legs.
Up in the frozen north, car batteries are changed fairly often. It takes a battery in good condition to start a car on a cold morning. People don't mess around with half dead batteries. Here in the warm south it's different. Because it's warm, even half dead batteries on their last legs can start a car. Don't expect those batteries to do anything extra, as they can barely do their main job.
If you plan on bugging out, make sure your car battery is in top condition. The same goes for the whole charging system. It's a common failure point in vehicles. Nothing worse than a dead battery as you try to escape from the zombie hordes.
I live in an area of NH known as the Great North Woods. I'm in my dome-i-cile out in the county with my lovely wife and a varying number of family and friends
-part red neck, part hippie but all country. Experimenting and enjoying the adventure of life.
