Battery 2 Pack for Panasonic VW-VBG130 & Panasonic Lumix DMC-L10, HDC-HS250, HDC-HS300, HDC-HS700, HDC-SD10, HDC-SD600, HDC-SD700, HDC-SDT750, HDC-TM10, HDC-TM15, HDC-TM300, HDC-TM700, SDR-H80

Actually better than expected. I tested out these batteries on a Panasonic Camcorder I have. I was pretty amazed at how long they lasted.As a test, I shot my backyard during a rainstorm, mounted on a tripod. I ran it for 2 hrs and the batteries were not even 50% drained according to the Camcorder. BUT the one thing I will say . . . it is not necessarily a smooth fit. Its a little clunky but it works. The first time I tried to mount it to my camcorder it gave me an error. I retried and found that the battery did not mount properly. With a bit of force, it snapped in with a loud click and then it worked perfectly. For me this worked better than I had hoped. Better and longer than the original OEM Batteries that I got with the Camcorder. How it mounts may be a worry for some but it seemed workable. I don't think it would be a problem over all.

Wow.... ABSOLUTELY TERRIBLE.Don't know how long these batteries were sitting on the shelf, but from first use to the 5th, after a full charge using the Panasonic OEM charger, the batteries don't last more than 15 minutes. My 9 year-old original Panasonic battery which these were supposed to replace, holds a 20 to 30 minute charge after NINE years. Yet these "new batteries" can't last more than 15 minutes. Too late to return for a refund. Waste of money!!

Came as advertising stayed, charged well, sure they will work great

I bought two of these for one of the advertised video cameras in the description. However although it does work in the camera, they do not play well with it's charger. Any time they are charged, it stops charging partly way though. You have to take it out, then put it back in several times.

bought for my panasonic camcorder HDC-TM15 and they fit perfectly and charged up perfectly too! my original battery that came with camcorder says 1.56 hours when fully charged now which means it has started to deteriorate over time. when i charged both of these up they both said 2 hours fully charged. i charged them using original charger that came with camcorder. my son just successfully completed training to become a Marine and i was worried my camcorder would die on me during his graduation which is why i bought these. i was a little worried after reading other reviews but decided to take a chance and i’m glad i did. i think i’m going to be able to capture everything at my son’s graduation ceremony now and not have to worry. they fit absolutely perfectly and charged up normal and now i have potentially up to 4 additional hours of recording time.

Works great on one of our Panasonic camcorders. Recommend to verify the exact model of your camcorder with the battery, their are difference in some models

Ordered 2 pack of of batteries as equivalent to Panasonic VW-VBG130 to use with Panasonic Video Camera Model SDR-H40P. Was pleased that the batteries are the same size as the original Panasonic battery that came with the camera but have more than twice the capacity so the recording time is longer than the original battery. Have used these 2 batteries only 2 weeks so it is too soon to say whether or not they have the same life as the original Panasonic battery. Batteries are packaged in individual boxes which are inside another box clearly marked with the Kastar logo and part number.

The batteries don't hold their charge and run out of power quickly. I recommend spending the extra money and buying a name brand product - in our case, it would be a Panasonic battery. These are a big disappointment.
