Re: How To : Replace the batteries in the alarm module
At first it didn't work at all - no cricket on crack sounds or any other to that matter.
I disassembled it, and interestingly my batteries and board look completely brand new with no rusting/cording whatsoever. I plugged it back in just to see what would happen, and the cricket on crack began - at least it was making a noise this time.
Even though the entire thing looks brand new, I guess I'll just have to replace the batteries nonetheless.
Here are some pics

Re: How To : Replace the batteries in the alarm module
Problem Solved!
Turns out the issue was not with my circuit board nor batteries. I proceeded further into the "piazzo" (is that what they call them?) tweeter itself and disassembled it by popping out the plate which is secured by snap on locks around the circumference of the lid.
Once that lid was popped out, i removed the metal tweeter, cleaned it up with alcohol, and solderer the center pink wire as it came off from scrubbing to hard. I took the tweeter seal, cleaned it off with alcohol, and made careful note to mount it back into its housing and placed the tweeter back in place.
I believe the issue has to do with that pink wire (which is soldiered into the center) touching the metal which prevents the metal tweeter from freely vibrating without obstruction, hence causing a distortion with the siren sound. I ensured that the pink wire was lifted off and not touching any part of the tweeter other than the soldered point. It might have also been the setting/placement of the tweeter somehow getting set wrong through the vibrations of the alarm over time.
GOSH ITS LOUD!!

Re: How To : Replace the batteries in the alarm module
Are these the batteries George?
I have replaced my alarm with a chirping model and I thought I would replace the batteries or at least take the old ones out of the old one.

Yes, that is the correct battery.

Re: How To : Replace the batteries in the alarm module
if you are ordering batteries get an extra 2 so they can go in the one I ordered a week ago. It is just a matter of time before bluecoupe will need some done also. This way we can have one "ready to go" for the locals.

Re: How To : Replace the batteries in the alarm module
Here are the pictures I took as I went through the replacement.
I put my alarm in a three jaw chuck and with the alarm spinning I carefully sawed through it with hacksaw with the edges ground flat, that way it just cut on one surface.
The board with four of the eight battery legs removed, all of them were removed and the holes cleaned out with a .045" diameter drill.
The modified batteries showing the one battery terminal converted to two. The negative terminals need to be modified, they are not as far apart as the positive terminals and this prevents the batteries from being installed the wrong way.
The siren in the half shell.
The other half of the siren.
The new batteries on the board assembled in the siren body.
The body was then glued together and taped as in post number one.

Re: How To : Replace the batteries in the alarm module
Hey Dave, did you test the alarm to see if it worked? Reason I ask I have found these china batteries do not hold a charge after a few days. I am asking if the car sits for a week will the alarm scream or not, and for how long? I don't have one that has bad batteries yet so I cannot order/test in service. I have tried a few of the other china 'green' rechargeable batteries, not getting any good service out of them, they self discharge fast. I seem to recall if you take the positive battery post off before the negative, does/should the alarm sound? I cannot remember if this causes the alarm to sound as if someone cuts the battery cable to steal the car or battery? Anyway, just wondering if the batteries are working, they are pretty inexpensive (but) if they are not of any quality, will they work (or last)? Last edited by onehundred80; Jun 26, 2015 at 11:38 PM.

Re: How To : Replace the batteries in the alarm module
I typed in the reply and then I saw that it was at the end of your post. This was because the end of your post was below my answer, how to you get half a page with nothing in it. It seems you add a period way down your post. On this little i Pad screen you cannot see it.
I could not be bothered to go back and edit my post.
I just edited it.
Why is that period so far down the post, you did it in this post as well?
