i dont think you should replace it unless its really old. one discharge isnt going to hurt it, mine did that a few weeks back and the battery wasnt dead per say it was at 8.1 volts so just low enough for the car to not start. i say charge her up drive her around for a bit and you'll be fine.

or figure out what the power drain is! I would not "just stick a tender
on it" Which are worthless If you don't have discharge isssues and drive it once a month!

My first battery, when it died, was dead...no recharge. Went out and got an Optima Yellow. It was dead within 5 months. It was of course easily recharged but I had to get a battery tender.

I noticed your car is a 2005. If it is a 6-speed manual, you need to make sure it's in reverse and the hand brake on when you park it. If not then that will drain your battery. A battery tender is a good investment, too.

I have an 07 and I do this because my salesman told me I needed to. Was this issue fixed after the 05 or do I still need to do this?

The longer you wait to start recharging a dead battery, the more damage you do. The longer the battery is in a discharged state, the less apt it is to recover and when it does recover, the less charge it will hold.

In an 05, owing to Federal regulations at the time, the computers would not shut down unless the car was in reverse and the e-brake set. That rule was lifted for the 06 and later model years. I believe it is still a good idea so I park in reverse with the brake on. It isn't required for your 07.

If your car is an 05 manual and you are parking in reverse and still getting discharge you may need to have the "reflash" to your ECM to correct the original electrical flaw that allows 05 manuals (even when parked properly) to discharge.

Get the reflash. I always park the BlueCoupe in reverse, lock the steering wheel, but never set the emergency brake. I also have both a priority start unit and a battery tender, and have had zero problems after the initial DBS incident.
