these batteries work great. I have a pet claw trimmer that eats batteries, and these guys run it for literally hours without much slowdown. Quick recharge (in a good charger), and back at it. Finally - rechargeable batteries that work the way you think they should!

I ordered these batteries and they do not work. They did not work when I first put them in the toy so I tried to recharge them. They would not recharge. I contacted the seller and they NEVER returned my call. I just wasted $25. Never order these unless you want to flush money down the toilet. Never order from the Battery Superstore!

Works great in my bicycle headlamp, just what the doctor ordered. I highly recommend them to anyone.

These new batteries held a charge for a few seconds. In the garbage now. First crappy purchase thru Amazon.

I bought these after reading multiple reviews on various battery brands. These seemed to have the highest rating across the board on multiple sites so I invested in 8 C batteries and some AA batteries for my trashcan, remotes, etc.

The batteries hold a charge for a really long time after charging even with daily use. In addition, you can charge up a set of batteries and put them on a shelf or in a drawer and they still have an excellent charge in them several months later even after sitting unused. I will definitely purchase more of these in the future if I need other-sized batteries.

Many rechargeable D batteries are just rechargeable AA batteries in a D case. Not these, have them in portable speakers and they work shocking well. Very surprised how infrequently I need to recharge them. Couldn't be happier.

I use these batteries for my "lake" boom-box and so far I get 3 lake trips out of a set of 6. They run constantly for 2-4 hours each trip and have lasted longer than the energizer batteries I replaced. Good product so far..

I purchased 14 of these in "D" for a satellite radio that I use as a portable. These radios are power hungry things. A regular set of duracell batteries lasts 8 hrs! These. when fully charged which takes around 12 to 14 hrs will last three days. I have been using the same two sets for about a year and a half now and maybe charged them 50 times or more and they last the same today as when I first got them. I don't know what could be going wrong with some of the batteries people have purchased but maybe they should keep trying to get a response from company and give it another try. One point that may be happening- You must use the charger that is made for these batteries specifically because they are 10,000 mAh (for D size) and 5000 for C size. This does make a difference. I purchased their charger for their batteries. Other chargers probably will not charge them up fully or maybe not at all because they are nickel metal hydride and regular rechargeable batteries are made up of different materials.

I've bought 8 so far and they've worked great. I use in multiple stair well lights and they last about 4 months before recharging...can't complain. Inexpensive especially compared to buying nonrechargable every 4 months or so. Great value!

we use sooo many "c" batteries around here. these are great and we haven't had to charge them often. this is a good company with a great product! use them in everything that needs "c" batteries.
