No one (in good conscious) can tell you it is safe to use that replacement battery.

It is possible that it will not work in that camera at all.
On the newer cameras, some of the camera makers have added battery verification code to their camera's firmware.
Sony is doing this on their newer cameras. It checks to see if the battery is made by Sony and if it is not, the camera will refuse to use it.

The other problem is the unknown.
Nearly all Lithium Ion batteries are made in China.
Some are made by companies that have poor quality control.
You can find many recalls of batteries by major camera companies and laptop companies due to quality control issues.
If the big camera companies and laptop companies can not depend on their battery manufacturers to
always produce a safe product, what chance do we have of getting a safe "no name" battery.

A defective battery can overheat and even catch on fire.
I suggest you buy a Sony brand battery.
