Question:

Do I have to change the batteries if my smoke detector is hard wired with a battery backup?

It seems wasteful to change them if they're not being used, but then again I don't want the damn things chirping at me in the middle of the night.

I was disappointed when I saw that the tracklist is exactly the same. I've been wondering if anything is different. I still have my original copy, so I'm not buying it if it's just remastered.
Tiger get the belt changed the correct mileage for changing is 70,000 miles or 3 years.Own and work on Audi in uk i change my belts at 50,000m its a very large bill if it breaks.Have a safe journey.
VIN etching is relatively not meant to deter theft, that's meant to make it extra handy to identity your motor vehicle if stolen. so far as overlaying the VIN, that looks very paranoid. i haven't heard of pretend reproduction paperwork. i'm specific it may happen, yet until you're using a $a hundred,000 motor vehicle, i could basically insure it properly and be secure.
if what ever they wanted is loose they,ll grab it and run ,but most thief's now days are smart enough to not want to be seen so the car alarm does work pretty well,it saved my car and belongings from being stolen and my car was unlocked at the time,most thieves are afraid of getting caught,so 9 times out of ten they will run and leave the vehicle alone,most car alarms now also disable the ignition system so it makes the car impossible to steal so at the least it will do is save your car from being stolen,good luck.
