4.0 out of 5 starsDoes what it should do!
By Keerthi Panneerselvam on March 25, 2005
I bought this battery for my PV-GS200 camcorder. Takes about 8 hours to charge completely and lasts for about 3 to 4 hours of intermittent shooting. Fits well for my requirement. I have no complaints except that it looks light gray (doesn't go well with my camcorder's body color) and feels somewhat plastic and low quality. A great value for $20.

2.0 out of 5 starsOk stuff... doesnt hold charge much... go with OEM
By NY Sam on August 8, 2008
Hi all,

Got this product for our new Panasonic GS320V, after reading reviews of several products, chose this one based upon the price and mili amp rating.

As someone else has noted, this is a thick battery and it tends to stick out of the camera.

The big draw back is that even after a full charge (the charger light goes off once the battery is charged) it holds up less than the original panasonic battery does - which is more than half the size of this.

Most of our recordings were done at Disney/Universal/SeaWorld shows. These shows typically last between 15 - 25 minutes. Also, a good indicator was the miniDV tape - which I recorded at SP mode - 60 minutes.

Almost all the time, I ended up using the viewfinder and not the LCD screen to save the battery life. I was not using any external light and the zoom was set to wide angle - most of the time. I did minimal close up shots. The reason I am explaining this is to show that I did very minimal stuff to prolong the use of the battery.

Anyway, now, this battery did NOT even last for 90 minutes at most!

The original OEM battery that came with the camera lasted between 150 minutes to about 180 minutes!

I would have expected that considering the size of this battery, this would at least last twice as long as the original one. But it only lasted about half or 3/4ths of the original one.

As someone has said, you get what you pay for!

For anyone who is into long shooting, I would strongly suggest buying original ones OR if you buying aftermarket ones, buy more than 2 or 3. Dont forget to buy additional chargers too!

If I used this in the morning and shot all day, I remember charging this that night.Read more ›

By Chilly Willy on January 12, 2008
Fully charged battery overnight, installed it on my PV-GS320, and...NOTHING.

It does not work. Total waste of money.

1.0 out of 5 starsCheap fake!!!
By B. Renat on July 4, 2009
However there are many good reviews of this product on its page, I think all of them are fake as the product is itself.
The battery keeps charged less time than that one sold with camera (<1 hour of working time). After 1 hour the camera turns off however the indicator of battery shows to be fully charged.
Totally disappointed of this purchase. Better to buy a genuine battery even if it costs more.

5.0 out of 5 starsIt's a battery!
By C. Lerner on June 26, 2006
You buy it because you need it, not because it compliments the color of the camera... It wouldn't matter if it was purple with green polka-dots - The dark grey on a lighter grey camera is irrelevant to me.

I got it, charged it overnight and put it on the camera where I took over 100 still photos and video taped some 45 minutes of continuous footage - all on the same charge.

Good product - in ANY color!

2.0 out of 5 starsBuy BRAND NAME Batteries!
By M. J. Bowen on June 22, 2010
I bought a Panasonic PV-GS200 Mini-DV camcorder in 2004. I had purchased a second battery (Energizer) that I used as a back-up, but as I was getting ready for a trip to Orlando, Florida, I wanted to get a hi-capacity battery. I bought the Digital Concepts BP-DU21 battery because it was a pretty good price and it promised over 6 hours of battery life. I figured I would need all the battery life I could get while visiting Universal Studios and Walt Disney World resorts.

Now, to be fair, the battery worked fine on the trip. But, after I was back home and not needing to use my hi-capacity battery as often, I only used it a couple more times. After about 4 recharges, it would no-longer hold a charge, so it is now a paperweight.

Of course, enough time had passed before it stopped working that the warranty was expired, but as I am on here now looking to purchase an additional battery for another summer vacation, I thought I would extend a warning to fellow consumers looking to do the same. I have heard similar stories from others who bought a third party battery to save some money. As much as I love to save, I am willing to pay the higher price tag for the Panasonic version of same capacity battery; I would rather buy a battery that is going to last.

2.0 out of 5 starsGood deal? Not necessarily.
By R. Andrews on July 9, 2006
Verified Purchase
What I assumed I was buying was a longer life battery, as advertised. What I got was a large battery lasts no longer than the smaller, standard battery that came with my camcorder. I totally discharged and recharged the it several times, but the results were the same. From that standpoint, it's not worth the purchase.I'd prefer standard life performance in a less bulky package.

5.0 out of 5 starsExcellent Off-Brand Battery
By John D. Beam Jr. on July 29, 2007
I purchased this battery and used it with my Panasonic SDR-H18 Camcorder and had no problems with it or its performance. I would recommend it as an additonal battery to a camcorder system.

I was surprised, considering the price, that the battery lasts much longer than the one that came with my videocam, but it does. I can run for several hours on this.
