I have a few things that use this battery, and they last quite the long time. They are heavy, they are bulky, and I believe they're using 6 cells in them, I think that's how many I counted on the one I accidentally ran over. Which on that note, yeah the battery was destroyed as about 1200lbs ran over it, but 4 of the 6 cells survived without damage, that's impressive and speaks to the build quality. Also the damaged cells didn't explode, so that was interesting. I don't know if my Highlander's tires could handle that explosion. Since I don't trust dealer tires on cars.BUT back on point, I bought it for my little 7in monitor for cameras, and whatnot, my ZOOM F6 (which it's really tricky to put on that device and practically doubles its weight, but that's ZOOM's fault for making the area to work in so tight), and some studio lights have support for two of them. So, this DEFINITELY ticks the value, amperage, and function for the money. Durable, inexpensive, and they have so many different "flavors" too. Like one that sacrifices 1A for an LCD read out. Will buy again. I also bought the ravpower version, which were near the same price for half the longevity as these. But you can buy this capacity with charger for like $50 and it's a nice charger. Love finding obscure quality companies like this.

These take forever and a day to charge but, they will last just as long as it takes them to charge. I use these in some of the devices I employ for mobile video recording and interview captures. They work will to power some of my LED devices. No charging or discharging issues. Recommended.

batteries arrived 75% charge. fit perfectly. i would buy again

I was happy they work for my cameras. They are a little tight but work...

I bought this make from this vendor for one reason. I needed batteries of this type, immediately, and this could be delivered the next morning.If they had worked only somewhat I would have been served.In fact they work GREAT. Fully charged they have fabulous life. I am thrilled with performance. Only odd thing is my Sony chargers have difficulty reading state of charge when charging. I thought were faulty but voltmeter said were full. And they lasted longer than my older Sonys.

I don't have any good way of testing exactly how accurate the claimed capacity of these batteries are, but I was able to run a portable monitor and wireless HDMI receiver off of one of these for about 6 hours and the charger claimed 1 of 4 bars remaining capacity when I was done, so I'm going to say that they definitely have good life for the price.

Not much to say. They are exactly as advertised.

great product, just what i need
