I've got 2x old car batteries that still have some life left. One was getting to be noticeably slow cranking (barely starting), the other still fine but didn't instill me with confidence for much longer.
So bit the bullet when I saw them for 25% off.
Anyway, I was about to take them for recycling when it was suggested to me that I might use them in the sheds to power lights.
Here's where my question lies
I am planning on getting these
https://www.ebay.com.au/itm/221921754180 and using 2x in each shed.
My queries are:
At 7200 lumens each, am I going to burn my eyeballs out in a 3x3 shed?
At 18w each, how long will it take to kill the battery (I won't run them empty as they aren't deep cycle)
What gauge wire do I use? Is 3mm (10a max) wire enough, or will they likely take more?
Note, I will use alligator clips to connect to batteries when in use as I don't want to leave them connected and potentially burn down the shed
Thanks
