Power2000 ACD-408 Rechargeable Battery for Sony NP-BX1

I purchased this battery as a backup for use with my Sony RX100 camera. When the battery arrived I charged it. The initial charge took a little more than 1 hour. I have used the battery about 4 times, and it has worked fine. If you own a Sony RX100, I would recommend you purchasing this battery as a back up. You will not be disappointed. It beats the alternative - shooting photo's and you battery is drained, and you don't have a back up battery, and must stop shooting while you charge your one and only battery. If you had a backup battery, you would simply swamp them out and continue shooting pictures. Highly recommend purchasing this product.

It came as promised, it fit . now need to see how long it last. I'am thinking it will be fine..

i guess it's okay because they are so cheap but the juice got used up too quick. maybe because the temperature i'm using them in is too cold?i bought 3 of these batteries to use in China for a month long trip. i didn't have a problems though because i had 4 batteries total.

I purchased this as a backup battery for my new Sony DSC-HX50v and it works great. I've went to several special occasions recently at which my original battery did not last thru the entire event and I was very thankful to have this battery. I am going to order more spares to keep on hand at this low price.

Needed back up batteries for my Sony action camera but just couldn't see myself spending $40 just for one at my local retailer. Plus the capacity on these are more for just a fraction of the cost. They work just as good as the one that came with camera even after being charged a few times already.

I love my RX1, but it inhales batteries. If the only option was the Sony battery, it would cost a fortune on top of the cost of the camera... But with inexpensive alternatives, I bought a bunch extra batteries. I don't see any difference in performance.

I wanted to get a spare battery for my new Sony DSC-RX100 but didn't want to spend $39.99 for the  Sony High Capacity Battery NPBX1 . Not only is this less than half the price, the capacity is greater (1600mAH compared to 1240mAH).

Fantastic buy as a Sony Replacement. Battery charges quickly, & OUTLASTS the actual Sony battery with 1600 m.a. vice the original 1240 m.a. Faster than expected shipping & a pleasure for the price on AMAZON! Thanks guys : )

OK battery. Does not hold charge well at low temperatures ( 32F/ 0C) but that is expected for the price.

No problem, Working fine. Price Is Right (like show)
