Kastar BP-808 Li-Ion Rechargeable Intelligent Battery for Canon FS10 FS11 FS100 FS21 FS22 FS200 FS31 FS300 VIXIA HF10 HF11 HF100 HF20 HF200 HF S10 S100 S20 S21 S200 HG20 HG21 M30 M31 M300 Camcorders

Despite the fact that this perticular battery pack does not look identical to the battery pack you would have gotten with your camcorder it functions completely and just as well as that of the one that came with your camcorder. It is good to have an extra battery pack if you are going to do a lot of videoing somewhere and need more time than one battery pack will hold. Mainly because you cannot use your camcorder when it is plugged into power and it would also be extremely irritating to have a cord coming out of your camcorder as you use it. Furthermore I highly recommend purchasing this battery pack because even though it does not look the same as the one you have in your camcorder it is the same and is at a much better price than sold in stores or in other listings where the battery pack looks the same as the one in your camcorder. My total costs for this item amounted to $16.83 and most stores sell the same thing for about %100. Amazon itself also sells this item for $40 excluding the shipping so this is your best option!

I purchased two batteries as spares for my new Canon Camcorder. I tried them both out and they worked fine. They both showed over 100 minutes available on my camcorder after charging so the "intelligent" function worked. However, after one use, one of the batteries quit working. It wouldn't charge properly. I contacted the manufacturer (SF Planet)and first they said they would replace the battery but later said they didn't have a replacement and would refund my money. They have refunded my money. I would hope for better quality, but SF Planet responded quickly to my problem. I would buy from this manufacturer again.

It matched the original battery, fit in the slot, and charged. Camera works on battery power again. What more could you ask for?

I thought this would be a piece of junk battery, and that the camera wouldn't recognize how much time is left for usage. I'm using it with my Canon HFS200 and it works great!! It works as long as the original battery if not longer. I'm so glad I didn't waste *80 DOLLARS* on the one from canon, when I got this for 5 dollars and it literally is the same exact product. Now I have a backup battery that's perfect for filming longer times, and since my camera is a battery hog it is useful as hell!

I purchased a replacement battery for a Canon FS300. Original battery is a Canon BP-808, 7.4V -- 850mAh. Replacement battery is a Kastar BP-808, 7.4V -- 1500 mAh. Physically, the two batteries look the same. But the Kastar battery will not charge. Upon closer inspection, it appears the small pins are bent and/or misaligned slightly. This could be a manufacturing defect or an assembly error. The defective battery (Canon BP-808 I need to replace) has a rapid RED blinking light indicating a battery issue when I connect the camera to the charger. When I insert the Kastar BP-808 into the camera, I don't see any lights. It is the same result as when I plug in the camera with the battery compartment empty. I have contacted Kastar directly as they offer an 18-month warranty.
