Does Liberty Mutual have renters insurance?

I’ve tried jumpstarting the battery in my 2015 Dodge Challenger, but it hasn’t worked. How much will a new battery cost?

I recently replaced my car stereo and rewired the whole system, but now there’s a whining noise coming from the speakers. My friend, an avid musician, says it sounds like a ground loop. Is there a way to fix the ground loop noise in my car?

Is there a way to get insurance information if someone at fault won't provide it? My neighbor's dog bit my son and the neighbors won't provide insurance information. We had to go to the hospital for the bite and we now have medical bills. We also have our own homeowners insurance.
