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

I ordered this BP-809 battery from Eaststar (through Amazon) based on good reviews for the BP-827 and BP-819 generic batteries, and the fact that the price was 60% less than the original Canon.I chose the BP-809 model because it is the right size for my camcorder. Bigger batteries last longer simply because they are large. In the case of my Canon Vixia HF20 HD Camcorder, larger batteries interfere with the start/stop button.I ordered a Sunday and received the next Thursday this battery of the brand "BestBatt".The battery is a dark charcoal grey. There is no marking on the outer casing, on the connector side it is marked "For BP-809 7.4V 1000mAh Li-ion" (the original Canon is marked 890 mAh / min 850 mAh).The battery fits snuggly inside the HF20 camcorder. As delivered, it immediately displayed 2 bars out of 3, and displayed the remaining time: 76 minutes in photo mode.After a full charge overnight using the camcorder power supply, the battery displayed 116 minutes (photo mode) and 101 minutes (movie mode).I set-up the camcorder in Low Definition mode, and left the camcorder run in a long, continuous shot to drain the battery completely. The camcorder took 55 minutes 48 seconds of movie before shutting down.Recharged again, and the displayed time was 121 minutes (photo mode) and 100 minutes (movie mode). Left it 3 days without power, the charge is now 95 minutes (movie mode).All these performance are in line with the OEM Canon BP-809 that came with the camcorder. We will see if durability becomes an issue, but so far the battery works as advertised for less than half the price of the original. Performs as advertised, 5 stars.

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.

I purchased a replacement battery for a Canon BP-809. The battery arrived and is not "intelligent." All you see when you put the battery in the camcorder is a red box with a "?" in it. You have no idea how much time is left on the battery. While it does power the camcorder, you have to accept a prompt on power-up to acknowledge that you have what the camera feels is a defective battery. I used it twice, hoping it would somehow become intelligent, but it didn't. Further, since you don't know when the battery is close to running out, the camera just powers off, and by my observation, the capacity was worse than what I was replacing. I tried to contact the seller, and received a response. They quickly informed me that the battery was not OEM, and I countered that it is listed as "intelligent" at the very least. I would answer their follow-up, but would have a new customer service rep on the subsequent email that I would have to rehash the issue too. After four such exchanges, I complained directly to Amazon who refunded my money with almost no questions asked. Buyer beware, you are getting what you pay for. Also, if you are concerned with aesthetics, the replacement battery does look funny amongst the sleek and shiny plastic of the Canon.

This is a replacement for the original one that was old and wouldn't hold a charge anymore. I thought I might have to discard the camcorder but Amazon had what I needed and at a great price.

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!

very good life batteryno canon label on itwhen i slide it in my canon fs200 for the first timethe sliders kind a stuck a littlebut after the third time chargingbecame fine, i dont know maybe its a technical thing that it meant to bebut its realy good it last exactly like the original battery life timecheers Kapaxen
