Hi!

I believe my alarm sounder battery is dead. My car doesn't make a peep when you set the alarm off, and I have a persistent "Alarm System Service Required" error I have to clear every startup.

I believe it's the sounder or at least that's where I'm starting with the silly non-serviceable battery.

Is anyone aware of which part numbers or new superseded parts there are to replace it? Can you use a high spec with tilt on a low spec car? Etc.. just looking for some guidance from folks who have already dealt with this. The earlier model year part is more expensive, and I somewhat worry about NOS batteries already being dead from sitting on the shelf.

Is there a way to just bypass the alarm all together to avoid these issues? My car lives a supremely sheltered life. As long as the doors lock I'm content.

 

if i could make all the alarm sounders in my vehicles die with a snap of my fingers, i would.

 

You have already bypassed it. You can't fit a high in a low or vice versa. There will still be a fault message. Easiest thing is to remove yours and match numbers. Most of the time it's marked in paint with a L on the case. No mark = high spec. Although it may have been changed as life is 8-years or so.

 

Weren't these parts superseded to a newer version, though?

Say I have a High-Spec I would need to order a superseded High-Spec in order to clear the faults, yes?

Is there a tell-tale way of knowing which you have without seeing the part? I have the reduced guard button on the driver's dash side.

 

Part numbers change, sometimes the part doesn't. Unless you have a build sheet or can have the configuration read from the car its a guessing game.

 

I put this in my 06 v8 vantage low spec alarm. The battery in the original had leaked and damaged the pcb board completely. I don’t remember where I bought it.

 

I bought the above Volvo unit from Aliexpress for about $80.00

I replaced my VARTA battery last year for $10 and a couple of hours of time. Some soldering involved as it wasn't a direct replacement battery. All Good!
