No, that's the SE version, which causes problems because it can't deliver sufficient current.

 

Ah - ok, thanks.

 

Can someone advise what battery to buy and from where?

Mine needs changing too.

 

Unfortunately it's not possible (AFAIK) to get the exact spec batteries in the UK (or Europe).

I changed my siren battery a few weeks ago when I also made an external battery box. I used CR123A photo batteries (as suggested by Mark E) and all seems well so far. I'm planning to put up a new thread showing what I've done (once it's permanently fitted properly), so anyone else can do the same if they want to.

It is possible (but I'd suggest not advisable) to tag a bit of solder onto the CR123A batteries and solder them into the siren. If this is done, great care has to be taken to avoid a possibly exploding battery eek!

A temporary fix is to simply disconnect the siren for blissful silence. You'll have to clear the 'Service Theft Alarm' message every time you start up, but apart from that there are no side effects.

 

I can confirm that this battery does not work! My latest mod is an external battery box to take 4 AA 1.5V batteries which I bought from Maplins. It is nor weather proof so have got it inside another plastic container I found. Just soldered the leads into the printed circuit board. However although it works with new Alkaline batteries they do not last long. I was thinking of sourcing some lithium equivalents. Any one got any thoughts on this?

I've been trying to get some info from Sanyo about supplies of this battery in this country . . . no luck so far, though.

So, these batteries supply the siren should the main battery be disconnected. Is that right?

Are they charged by the circuitry to keep them topped up?

A proper approved car alarm needs to have an internal backup battery should the main battery be disconnected, so your assumption is right.

The batteries are not rechargable, so they will drain over a period. That period is meant to be about eight years, but most have found it's nearer to five years (with the exact spec batteries).

 

Hi Guys, I too am plagued by this. Am I just getting this wrong that we are not able to get the batteries in the UK? If not why not the car is CE approved so should not have any illegal components etc, etc.

If they are available elsewhere in the World why can we not source them there?

As i say if its me be daft ignore but I am confused!

My car is ten years' old this December - I dread the alarm problem on a daily basis..

Are you sure the alarm is still there? Perhaps someone, like me, got cheesed off and removed the whole unit!!

Definitely there. Goes off in hailstorms!
