Works fine with my JVC camcorder and the battery monitoring built in to the camera is compatible with these batteries. Obviously, they are larger than the original battery but this does not interfere with anything. The bonus is that you get much longer runtime. I tape mainly my kid's basketball games and the standard battery gets me one full game and maybe a little bit of another. These batteries last two full games and into the third. If you don't have any extra batteries, get this kit! It makes life a lot easier, especially with the AC/DC charger. You can charge one battery while you tape with another. Otherwise, you have to charge the battery on the camera, which is no fun at all. With the price of this kit, it's a no brainer.

Bought for JVC GZ-HM35BUThis is a good product and good value. There are 2 batteries and 2 ways to charge. I like the car charger adapter. The batteries are slightly thicker than my original battery but the fit is perfect. I haven't noticed an issue with battery life, plus there are 2 batteries so I make sure they both are fully charged and with me for longer recording events.

The batteries were a perfect fit camera, have a long life, and at a good price.

I am a Videographer and it's very important to have good tools for the trade! Been using this type battery on my equipment for years and have never had a failure!!They have a GREAT Longevity! Will continue buying them as long as they are made!!!!The life of the battery is just unreal!

I bought these to augment the battery that came with my JVC camcorder. The battery that came with the camcorder is rated at 700 milli amp hours (mAh) and the camera did not come with a stand-alone battery charger.The charger that came with these batteries allows the batteries to be recharged using a standard wall outlet or the cigarette lighter in any car or truck.The biggest benefit with these batteries is that they are rated at 3000 mAh. All batteries are rated in terms of mAh. That figure represents the storage capacity of the battery. In this case these batteries have about 4.3 times the capacity of the battery that came with my JVC camcorder.There are dozens of batteries being offered that will fit my camera. How do I choose? When purchasing batteries, be sure to look at the storage capacity of the batteries in question. The storage capacity of batteries this size is expressed in mAh (milli ampere hours). The higher the mAh number, the more energy the battery stores. This battery has 4.3 times more storage capacity than the JVC battery that came with my camcorder. Want to compare more batteries? Try this - divide the cost of the battery by the number of mAh. For this battery, $32.99 divided by 3000 (mAh) equals $.011 per mAh. For the JVC battery, $22.99 divided by 700 (mAh) equals $.033 per mAh - 3 times more expensive!

So I bought these because my stock battery was horribly degraded and I went from 30-50 mins of record time and after I charged this battery to 100% it said I could record for 190 mins! Its a big heavier than the old stock battery but not by much. It is larger than stock since the stock was 700mAh and this is a 3000mAh. The charger is nice but I wish it could charge both at once. The charger is universal.

Good replacement batteries for my JVC Everio GZ-E-10BU Camcorder. My original battery lasted about an hour. Or, one volleyball game and the camera would get really warm. It used to concern me. These batteries have lasted through 1 volleyball game and a soccer game and then some more!! They did not get hot. Maybe there are some out there that last longer but for the money a couple of hours is good for me. I will admit I did not clock them but I know I took it out of the camera when there was still one bar left so they could have lasted 4 hours. But, I decided to recharge. I did have problems with one battery. It fit really tight in my camera and in the charger. They sent me a new one out the next day and it fit perfectly. Thanks

Battery life is short.
