Synergy Digital Camcorder Battery, Works with Samsung SMX-F34 Camcorder, (li-ion, 7.4V, 1000 mAh) Ultra Hi-Capacity, Compatible with Samsung IA-BP85ST Battery

The battery seems to work but it is to big. The battery fits into the battery slot but it is to tall for the locking clip to engage. I am able to force the battery cover to close but its a bad fit. Update... this is a very poor quality battery. Not only does it not fit properly but it does not hold a charge over a weeks period of time.

This is a replacement battery and it worked fine right out of the package. No issues so far but I haven't tried to charge it. Seems to be as advertised.

The first time I used the batteries, the initial run time of my camcorder was 15 minutes before the battery died. I didn't bother trying the 2nd battery as the first was complete garbage!

I used the battery for a used Samsung camcorder. It is strange though that I thought I was receiving a real Samsung branded product and didn't. However, it does work just fine.

Battery worked for about a month

Good battery
