JUMPSTART A CAR WITH AA BATTERIES!
Dead car battery? No problem just go home grab the solder gun, connect a bunch of AA batteries together and a few hours later you might have an alternative to jumping your car without using jumper cables and a little help from a car with a healthy battery.
In all fairness using AA batteries is a really unnecessary and a lengthy process but this video managed to make it fun. The guy shows us that this is possible and entertains us while doing it.
Soldering the AA batteries in a series might pack enough power to start a smaller engine car but it is a real pain in the ass as you will find out. Check out the video and remember although possible it is intended as entertainment not as a real way to start your car every time you run out of juice.
