I had previously bought the less expensive knock-off brands and they just didn't hold up.

Decided to get the Panasonic batteries even though they are now made in China hoping that these go through a more stringent quality control and is higher quality components compared to the much cheaper knock off replacement batteries.

I prefer paying a little more and getting a genuine Panasonic battery, such as this one, compared to the cheaper knock-offs.

This is an actual Panasonic battery, not a cheap knock off.
