I know that the dealership has a memory saver (back up battery they use while swapping). Just wondering what I will have to re-enter. Possibly stereo code (will have to dig for that) Maybe all my radio stations.

Any ideas on a replacement battery? Does it even matter?

 

I recently changed my dead OEM Panasonic with Autozone's Duralast Yellow. It does the job for $80.
You'll have to set your auto up/down driver's window too. Just hold up for 5sec, then down for 5 sec.

 

it will also erase memory seat settings

 

you won't lose the radio stations, just need to input the navi code (if you have one) and the radio code.

 

When I unplugged the battery toi clear the CEL code, it does erase ALL radio station/Treble/Bass setting. You need to re-enter radio code and reset the radio station, and the dash-board lightness (when you turn on the light).

 

So if the battery is disconnected, I will not lose any tele #'s stored?

 

I just changed my 3 year old battery yesturday. I have a 04 and I lost all the radio stations saved. You have to enter the code and re enter the stations.

 

I changed my stock acura battery to an optima redtop but I did not lose anything except i had to reinput my radio code.

 

TSX takes a 51R. We make Optima batteries and don't make a Red Top for a TSX only a Yellow Top in the TSX size.

 

That's odd. I have a Redtop 35 =]. It works great.

 

just disconnected my battery today cuz i thought it would reset my oil life(changed oil myself)but it didnt and stayed the same..then i had to enter a code for my radio..does anyone know the code or how to reset the oild life?

 

Try this: (It works for the 05 but that doesn't have the oil life)

Turn off car
Hold Select/Reset
Turn on car to ignition II
Keep holding for like 10 seconds


Also...the radio code should be with the stuff that came with your car. If not check the side of the glove box. If it's not there, check the underside of the fuse box under the hood. If it's not there go to the dealership and ask them to pull it up for you. Some will try to charge you but it should be free according to Owner's link.

 

thanx man i just did it and it works ok..but does the timer adjust back to itself or do you have to do it? oil lifes still the same might go to the dealer ship to see what i need to do...
