Do not think that just because your battery can no longer power your vehicle it’s useless. The hundreds of amps required to fire up your car may finish off your battery while under your hood, but there is an excellent after life. Yes, these batteries are capable of being used in many other ways, providing plenty of juice.
The same goes for batteries found in laptops and cell phones. Just because they can no longer power those devices does not mean they are useless. They are often times suitable for many smaller devices. And those larger car batteries can even be used in conjunction with solar panels to provide backup emergency power!
