Rechargeable C Batteries, 5000mAh Ni-MH High Capacity C Cell Battery New Retail Package, Pack of 4

I have never purchased rechargeable batteries before. I just have hoarded batteries for a long time because I didn't even know about these. Thank you so much for making such a quality product and your charger works wonderfully they're charged in no time at all I would recommend them to everybody.

I generally love EBL rechargeable batteries. I was able to test these EBL type C rechargeable batteries with my Amazon Basics battery organizer tester and they are partially charged. Now I will be getting an EBL 8 bay charger so I can probably charge these batteries!!!

As someone who made a career with computers and electronics (started when I was 5 years old), I have always had an obsession with batteries, especially rechargeable ones. I decided to make this review to give everyone my perspective on these EBL C size Ni-MH batteries. This review will be an ongoing review and I will update as I get more information to present. I ordered two sets of batteries for a total of 8. Four of them will be used for my Sangean HDR-16A radio, and the other 4 as spares to swap out when needed. The first four I ordered came as a package with a charger. The next four I ordered the next day, exact same brand and model/size. When I received the first package - batteries and charger, I noticed the batteries said "Pre-Charged" on them. See picture. I put all four batteries that are supposed to be pre-charged into the charger. I figured if they were already charged, the charger would top them off before I used them. It took over 4 hours before the charger said they were full. I decided to see what rate the charger (EBL) was charging them. I discharged the 4 batteries for about an hour, and then started my testing. Here are the results: (I have averaged the numbers due to the charger charging at various duty cycles. - I used a stopwatch and ammeter.) With 1 battery in the charger, the rate was approximately 1000ma for the one battery. 1000ma With 2 batteries, the charge rate was 1000ma per cell (2000ma with a 50% duty cycle) With 3 batteries, the charge rate was 660ma per cell (2000ma with a 33% duty cycle) With 4 batteries, the charge rate was 500ma per cell (2000ma with a 25% duty cycle) So according to my rough calculations the batteries took approximately 2000+ maH of charge. The batteries are supposed to be 5000maH, so they were about half full. NOT PRECHARGED, or at least not 100% charged. I decided to get a bit more scientific with the second set that arrived today. I took two of the four batteries and put them on a different charger that keeps track of the maH put into each battery. The results were 2550 for the first battery, and 2539 for the second. Conclusion: They are shipped at 50% charge, assuming they do have the advertised 5000maH capacity. Originally I was going to skip the full "NOR" test on my charger, and just swap out batteries in the radio when the low battery light comes on, followed by a full discharge, then a full charge and reading the total maH put into each cell. I changed my mind, and decided to do a full NOR test. This test fully charges the battery(s) and then discharges them to cut-off, which is just under 1V. The total maH is then read off the charger which is basically the true capacity of the battery. It then fully charges the batteries leaving the result on the display.

I use lots of batteries for frameless candles so I appreciate how quickly these recharge.

These batteries are great I have recharged them every two weeks in a light fixture which has a timer on it. They work great and save me a lot on buying batteries. Almost a year ago was when I bought them.

Good product, recharge in less than 60 minutes and holds charge for several months in stored emergency flash light before losing some power. Usually recharge alll batteries every 3 months to ensure adequate power if needed.

Good quality

Batteries only lasted 2 months (about 5-6 times recharged and used). Then, it completed gave up and stopped working. They should issue me a refund because product was falsely advertised as (100 times use) Refund was issued.
