Query: This is a Power2000 battery

This is a Power2000 battery (NP-400) not a Konica Minolta battery. I've had these batteries before and have not liked them. They don't hold a charge like the Minolta battery or last as long. They are inexpensive so if you want to save money they will work but the tradeoff is a shorter life.
