I am not sure I can find these specific ones I have, as they are years old. Energizer seems to have changed the look a bit. And mine are only 1300mAh - new ones are 2300mAh. But I am assuming they still work the same. May just take longer to charge. I only tested last night... but batteries were almost dead & I watched the battery bar climb on the Luna OSD as I played.
I am going to buy another set today from a store & will do more testing with newer or another brand.
