Query: 3rd party batteries are a bust

This seemed like a cheap alternative to shelling out 50 bucks to Motorola for a new Q battery however, I have recently discovered that when this battery is in my phone, it will not sync with my computer, but when I have a Motorola battery in it syncs just fine.I have had other problems when using third party batteries in other devices such as laptops etc. The lesson to be learned is; spend the extra coin for a manufactures battery to avoid compatibility issues.
