This is very much a case of much to do about nothing. I removed the battery on my S3 a good 4 years ago and it made no difference what so ever. With the battery in dead I had "unknown device" problems with Windows, but as soon as the battery was removed the device worked flawlessly.
Sonicxtacy02 you right. I tried it without battery and it works. But fixing time is longer.
I think my problem is about BU-353 location in car.
Here is not good location. Fixes very hard and long time. Sometimes can't fix.
I tried here this morning and better result.
My Guess is the defroster lines are causing you interference. Unless you have a sunshield windshield that contains many small metal particles to block sunlight you should be able to mount it on your dash and get better results.
Actually i thought this. I will try. Thanks.
That is a good idea placing the battery outside. Makes it much easier next time it goes kaputt. I shall remember that when mine becomes weak again.
BU-353 original battery is 5.5 mAh
BU-353 modified battery is 65 mAh (Maxell ML2032)
Be careful of where you mount the new battery since it may block your reception.
Personally if you can take it apart and change the battery and you got it back together ok then I would say it is worth while but I would just replace the original battery. Why worry about something minor that you might have to do every 3 years or so. Not to mention by then you are better off getting something newer with better hardware in it.
New battery on the bottom. So i don't think to block reception. Final looking in post 17. I would want to buy new one but not necessery. I paid 8 USD for battery and holder. Have cheaper batteries too. But Maxell is better quality. In conclusion its working perfect now.
