Still haven’t found the best NPF Batteries apart from the originals made by canon and Sony.FIRSTPOWER, for making this has done very well. However I feel for this effort, they can do better with the built quality and battery life. I don’t regret buying this.

Cargan súper rápido

I used these batteries to power my field monitor for a July 4th hip hop concert. One battery powered my monitor from 7 pm to 2 am... that is seven hours, and the battery only went down one bar. It takes a long time to charge the battery, but it is worth it for me. The LCD screen on the battery is a win too because you can see the usage and charging status at a glance. Although the batteries have a weight, I did not notice the weight when shooting on my rig.Highly recommended.

I am really disappointed but I will give these another chance because I really want the batteries.I used the USB outlet on one of the batteries for a USB fan. It drained completely. I did not charge it once I got it. It was half full. Not charging it completely should not be the issue here.Once the battery drained, the screen would not show a percentage because the battery was completely dead (understandable).I plugged it in for hours. I was wondering why the battery screen never turned on. I haven't used the second one for anything other than doing a charge test to see if the screen would show charge progress and it did but I did not drain it so there's only one way to see if it'll do the same thing.I'm assuming the second battery will do the same after I completely drain it. There is nothing in the description that says I shouldn't drain it 100%, otherwise, the battery can't be charged again. It's a lithium battery. This should not be a problem.I am doing a replace and return just this once, which is something I don't do for any product. I might just return it and stay away from this brand.This is really upsetting so I am choosing to return the batteries for good. I needed these for my field monitor. I tried both ports. Both ports on the working battery are charging the battery but not on the dead battery. I'm not doing any more tests. These are brand new and I consider the dead one a defective battery. The second working one is not worth the wait to see if it'll do the same thing.
