Wondering what to do with a lifeless car battery? It turns out that you can use an old car battery to help you out when SHTF, such as power up a computer or power up some lights when everything goes dark! So before you throw away that old car battery, you may want to hold onto it for that pivotal SHTF moment. Read below for more tips!

Many “dead” car batteries are actually perfectly good batteries. They just can no longer provide the hundreds of amps needed to start a car. Many “dead” sealed lead acid batteries are actually un-dead batteries that can no longer reliably provide a couple of hundred watts of power needed to keep a computer running in a power outage.
A couple of years ago I decided to add another small solar panel to the collection I have on my roof. I have a 5 and 10 watt. This new one is a 20 watt. It is dedicated to providing emergency power for lighting, a small fan and other misc. small low voltage devices.
For this setup I needed a battery since it would need to be able to provide power 24 hours a day. I decided an un-dead car battery would be perfect since the largest load it would need to power for any extended period of time would be less than one half an amp. There is quite a difference between 200 – 600 amps and a half an amp.

Fascinating – I never really considered using the energy from a car battery for anything else! That would definitely come in handy during a SHTF moment and you need to power up your computer to do some quick research as to what is going on or you need some lighting in the house so you can get your bug out supplies together!
