Comments

kep: Just finished charging in a powerowl charger. Took 14 hours on slow. They got up to 108F before I put a fan on them. 1 Battery said done. I took it out and put it back in. It started charging again and finished with the other 4 about the same time. I put them in a led flashlight and it's just as bright as using alkaline. No other testing done other than they work so far. Why they all got hot in the last few hours of charging? Don't know. To early to say happy with, or any other comment. So far so good except the hot part.

Carle Churly: They are what I expected them to be.

Henry W. Herrera: Not much to say. Charged them up using a good charger at no more than 400ma, heat is the enemy of batteries. Hi charge rates will cause the batteries to heat up. I wanted hi capacity batteries because I’m using them in an outdoor flood light. All 4 charged up fine but only time will tell how long they will last.

Mark Curtis: My testing of four of these cells indicates their actual capacity is between 7099mah and 7673mah.

Their ESR/IR is typically 18 to 21 milliohms when fully charged. This figure is about double that of higher quality cells which are also rated at 10000mah. This limits there ability to deliver current to devices which draw a significant load.

I haven't tested these cells for long-term self-discharge or service life, yet.

Ben: I'm using these batteries for a motion sensor light inside a garden shed. I had one battery fail after eleven months. When I tried to charge it, the digital readout on my charger indicated an error, no matter what I tried. The other 3 batteries were fine.

I emailed the company to ask for help with this issue and they sent me a whole new pack of 4 batteries for free. Exceptionally helpful, fast, and generous support. Would definitely recommend.

Pony: These batteries are not worth buying. I purchased two sets of four batteries. I started out by discharging then charging twice. I used them in a stereo. They worked good the first time. Tried charging again and two of the batteries won’t charge. They’re garbage.
Update
The company reached out to me. When I tried getting ahold of them they wouldn’t acknowledge my messages.
Now all the batteries won’t hold a charge.
Save your money. These are garbage batteries and the company is no better.

Full Throttle Repair LLC: First, I would like to say that I have went to the big box store and bought name brand D size batteries. They weigh just a little more than a paper clip. I took a dead one apart and realized it is nothing more than a cheap Chinese AA battery in a D size case.

Now, on to these batteries. I was shocked when I received the package in the mail because of the weight. These batteries weigh almost 1/3 of a pound! they are beefy and have some weight to them. I bought them for use in my stick pump to transfer diesel for my heater. I charged these all the way and have pumped almost 500 gallons and they are still going strong! I can't believe how much power these bad boys hold! They do tend to "dog down" a bit in the cold (-20), but just a hair. Regular alkaline batteries would get me about 20-30 gallons before the batteries were shot. I am actually going to place another order to get more of these.

yalch⭐yalch⭐: I have been using these batteries over two weeks by charging them twice a week while I was using them in my flashlights and my small project power station is it power source to test d programming boards and small electronic devices. These so far have been the best rechargeable batteries that I have ever owned, as they don't heat up because they can handle high discharge rate and they are leak-proof and I assume they do have low this charging rates than they are not in use, so they keep the energy while in storage mode for a long time. And they also accurate on their capacity rate, it takes a full charge for full capacity and it really last long even though van I use them heavily on my big outdoors LED and non LED flashlights. Once I got them in my hands I realized how quality they feel they are definitely heavy which tells me that they got a good structure in them and also if when you drop them they don't vent so that's a quality battery right there out of the box. I definitely we commend these batteries especially after seeing how they perform and have they are accurate to what they described in their specifications. I have ran a couple tests and charge them multiple times and I...
