POWXS AA Rechargeable Batteries, 16 Pack 2800mAh 1.2V Ni-MH Pre-Charged Double A Batteries, High Performance & Long Lasting

I have 2 different battery charger / diagnostic tools that measure battery capacity by charging and then discharging the battery and measuring how much power the battery provides. These 1100 mAh AAA batteries (16 pack) all showed to have capacities around 900mAh. I ran each battery through this charge / discharge / measure cycle two times and got this 900mAh result. - I'm fine with this - just know these are probably not 1100mAh batteries - but the price is right and all I care is that I have some batteries laying around to pop in the dying remote. - Just popped 2 into the cordless handset and it was happy - no data on longevity yet.

For years, I didn't think there was too much difference between rechargeable batteries. If a battery is the same materials and has the same rating, it's the same as the next battery with the same materials and ratings, right? WRONG!When I first received these batteries, they were all nearly dead and needed to be charged... so I spent the next few days charging all of the batteries. (My charger only charges 4 batteries at a time, and I bought both the AA and the AAA sets.)Then about three weeks passed before I needed more batteries for the kids' toys... imagine my surprise when I discovered that EVERY ONE of the batteries I had already charged were all dead again. Just sitting there, not in use, and they all discharged!So, thinking it was just coincidence or bad luck, I spent a few more days charging each and every one of the AA and AAA batteries.. this time checking them with a meter before and after to ensure they were charged.Again, when I needed a battery, the entire stack were all dead again... and my meter confirmed that fact. *GASP*I ran to the local hardware store and purchased a few rechargeable batteries (Brand name) and they were fully charged when I got them home AND those not in use held their charge for the time it took for the kids to kill the batteries that were in their toys.I am not the only one who is very disappointed. My grandkids were quite disappointed when they had to wait for me to go to the store and even commented, "But Granny, you have brand new batteries right there" while pointing. How do you explain to a 4 or 5 year old that sometimes you buy something that is simply junk?The cost of these batteries isn't much, but it was money wasted considering I had to go out and purchase other batteries elsewhere. Next time I want to throw money away, I'll take a few rolls of coins and throw them from the rooftop... at least the kids will have a blast searching for them in the yard.Edit:The seller saw my review and contacted me directly to offer a full refund. I don't know if I just got a bad batch of batteries, or if they sat in the truck for delivery too long (It's very hot where I live.) or what caused the entire batch to be bad, but I must say that the customer service is OUTSTANDING.

I'm using these batteries on my outside fence post solar lights they tripled the time before I have to recharge them if we have no sun when it stays cloudy for a period of days. They recharge very quickly.

Just picked one from the box at random, fully charged it, then ran a test cycle. Discharge current 0.2 amps. Only delivered 2186 mAh.This was not completely unexpected. Sad that almost every manufacturer exaggerates the capacity.

These batteries have lasted me longer than the regular batteries that I buy in the store. I have charged them and they are still working so I can listen to my radio and do my morning workout.

The batteries arrived needing charging.As far as longevity, their is none!With a negative value for the money, seeing as I had to take the time to package and return the batteries.Charged about 10 hours, charger indicated a full charge. When put in a battery tester, it was just barely in the "Green" (Good) Zone. Used batteries in Emay Oximeter and they lasted 4 hours before failing. I hoped that they would perform better after repeated charges - never happened. My charger can be switched between 3 different types of battery chemistry. It can even "recharge" non rechargeable ("regular") batteries. A recharged standard Alkaline battery (not designed to be recharged) lasted almost twice as long as these "rechargeable" batteries.An extremely disappointing experience to say the least!The item was obviously returned.

These batteries are wonders! They charge fast, and power for a good amount of time! I used to buy new alkaline battery packs every month...no longer, I’ll simply recharge! Fantastic!

All of the batteries tested at our above the rated capacity. Many behaved very close to each other so I'm expecting they will last quite a while in small battery pack uses.
