Before buying this product I have checked the compatibility of the battery with my tomtom one 1st edition looking at the photo seller and comments. This would have been. Upon receipt of the product, and of course check the polarity does not match the origin. I'll have to play the soldering iron to reverse the plug. So I confirm that battery is not identical to the original and attention to it only 1150 mAh instead of 1350 mAh.
