A 3rd party battery won't damage your camera. The issue is that, over time, sometimes in as little as 6 months, they loose the ability to hold a charge for extended time. So you will not get anything like the battery life you do from an OEM battery.
The key to aftermarket batteries is buy higher amp hour and make sure it is lithium or better. The old niCads would take a set if used infrequently and would not charge properly. The newer lithium's don't do that but never short out a lithium or charge it in a charger that is not for lithium use. Why? Because lithium's tend to explode if improperly charged or shorted out. If you can buy a higher amp hour then your camera will operate longer on the higher amp hour battery. To see the amp hour there is usually marked for example as 75mah and one marked as 100mah will last longer then the one marked 75mah. The "mah" means "mili amp hour" and is always stamped someplace next to the voltage marking and the stamp 7v would mean 7 volts like a 9v means 9 volts or 12v means 12 volts. just never short the positive and negatives terminals by putting a battery in your pocket full of change. I have seen a few burnt legs from that action. A lithium will get hot or explode if shorted out as coins are metal and are great conductors of electricity. I have seen a few military batteries that exploded by being shorted out. Any brand is a good brand you just pay for brand name and the same goes for car batteries.
