Simply ELECTRI-NOMICAL ..

[TigerTrax]

Just a note for all those who .... over time ....
have added... electrical stuff and made your battery terminals look
like Mrs. Calabrese' spaghetti bowl.....

One of my main battery cable terminals broke one night ... while working in the garage. I looked at it and said.... 'that sux!'
So off to my local parts store to find something of 'more substance'...

Shazbah! I found these neat very substantial ALL COPPER battery cable connectors ... about $1 ea. They slip over battery posts and use normal screw down.

Took them home and realized the wire connector a bit large so I crimped a metal sleeve around the wires, slipped them into the 'copper cavern'
then 'whacked a good' crimp with my.. trusty 5lb hand sledge.. then bent  it to about a 90° drop angle.

If this terminal breaks..... I'm laying at the bottom of a ravine!

You might want to lay some solder into that crimp joint.
