Q: How to tighten battery connectors

asked by on September 24, 2016

My back car lights were on and I couldn't figure out why I didn't know if it was the break lights or what. Later that day my battery died and my granddad said he loosened my battery poles so it wouldn't drain my battery (this was the next day) and I said it was already dead so now I need to know how to tighten the connectors back so I can charge my battery. Please help
My car has an automatic transmission.
