Rated 3 out of 5 by ProfessionalAmateur right battery for the wrong camera or vice versa
I was forced to buy this battery for my alpha 55 SLT camera, since the battery that came with the camera lasted on for approx 400 shots (this was as mentioned by sony, no surprises) with 18-55 kit lens. I was going on a vacation and was not sure if I would have the option to recharge the battery regularly. The other features of the camera were nice so I just didn't care much about the battery life at that time. I am repenting now!!
Now, with the new 70400G lens which I have purchased, the battery lasts hardly for 200 shots!!!!!
Its my bad. I didn't give enough consideration to battery life.
This is a good battery for point and shoot cameras BUT not for SLR/SLT/NEX cameras!! Please make note of this, before deciding to buy these cameras!!! I am learning it the hard way
I have heard that sony is coming up with new models in the near future which have a different battery and give excellent battery life.
But I am screwed!! After so much investment I can't even go to a different brand ($1000 for camera+$1600 for lens$80 for battery)

Rated 5 out of 5 by rkreiss Battery Life NEX cameras
I have a NEX 5K for a year now.
Purchased an extra battery soon after getting the camera. Just returned from 3 week in Africa and prior to leaving purchased another battery. This gave me 2 while on game drives and one back in camp charging.
Most of the time, the battery lasted for 8 hours of of the 2 game drives. Only twice did I have to swap batteries during a game drive.
No power at night to charge the batteries.
Most of my photography is stills not movies.
No matter what camera you own, digital photography uses battery power. One should have no less than 2 batteries to insure you have power during your days picture taking.

Rated 1 out of 5 by Nettar66 Camera returns error to turn OFF, then ON again.
When the camera is first turned ON, or awakes from sleep, the first photo will fail, returning a camera error with this battery. You must turn the camera OFF, then ON again. Extremely annoying. I suspect that it can't deliver enough current to truly boot the camera up and allow it to process the shot. Surprising that it is a Sony battery. Don't buy.

Rated 2 out of 5 by jpt0521 Needs improvement
Battery is large, relatively heavy, and requires a special charger. It has respectable life when freshly charged but loses charge rapidly during storage. I can't store the freshly-charged battery for ~1 month without complete drain. VERY unreliable for the cost.

Rated 4 out of 5 by MaysEffect PRE-CHARGE BATTERY BEFORE USE
i am only writing to warn people to pre charge batteries before first use. i dont know if some people do or do not do this but all batteries should be charged to its optimal level before the first use this is important to overall batter life, and charge capacitance. some people forget and have complained that the batter is useless or terrible.
IF you do this first and the batter is still not up to its optimal level then you can complain.

Rated 5 out of 5 by Puma12 Why does everyone say this battery underperforms?
First, let's cut to the chase. This battery at first will be pathetic. It will only give you 40 to 50 shots. You have to use the battery for several weeks before it "burns in" and reach 200-300 shots per charge. Used this battery for a year now. Still no capacity loss. People who reviewed this battery, didn't use it long enough. Shame.

Rated 3 out of 5 by amymirandamakeup Take up to 20 photos and the battery is gone
I love my nex5 camera, but the battery pack has a very short life.. I took a few photos one day and i had to charge it again next day.. its like every time you do a session you make sure you either have another battery or charge it for a few hours. The price of $80 is quite high, as with everything sony.

Rated 1 out of 5 by FLCAMERAGUY Battery Life is terrible
When I first purchased this camera, the battery probably lasted about 50 photos. I've had this camera roughly a year now and the battery life is down to 20-30 photos. When using a flash, the battery life numbers should be cut in half. Today after fully charging the battery all night, I took five pictures using the flash and the battery was down to 19%. It is ridiculous, please make an add-on battery pack for this camera. I don't normally post reviews but specifically created a Sony account here so I could post this.
