RayHom D Batteries Rechargeable 10,000mAh Ni-MH High Capacity Battery (8 Pack)

Good batteries with a lot of capacity. The issue is the batteries don't have the capacity anywhere near the 10K that is listed. I have a smart charger that can test the capacity of the batteries and the highest was about 6K. The Rayhom batteries were much better than the EBIL batteries that had the same 10K rating so I kept the RayHom batteries even though they didn't meet specifications.

I bought this 8-pack and the deluxe 8-cell charger at the same time. I charged the cells and put them into my fan (uses 8 cells at a time).It didn't last long. I took the batteries out and used my battery checker. I had 5 fully charged cells, 2 marginal and 1 dead.I put the last 3 through a 'conditioning' cycle and a charge cycle. 2 recovered, the last never did.AMAZON, do I have to return the whole 8-pack? If you send me a replacement 8-pack, what if, once again, a few cells are bad? Can't I return just the bad cells?Avoid these problems, avoid this product.The 5 good cells are strong and reliable.

I did not review this product earlier, because I had not had the opportunity to use it. These batteries proved invaluable in powering my family's portable satellite radio when we had to evacuate our home in the face of a wildfire. The batteries kept the radio going far longer than we expected, and they required recharging only once during our 11-day absence -- even though the radio was on almost non-stop. I would recommend these to anyone who needs reliable, rechargeable batteries for any application.

I bought these after reading reviews and so far I'm happy. They are hefty so I feel pretty certain they are really D cells and not C or something or something else inside. Bought them primarily for a remote control robotic arm on tracks. With name brand alkaline batteries it wouldn't do half of what it does now. Bought enough to have charged spares and so far the first set is still going strong.

They work.

4 out of the 8 batteries have died and refuse to take a charge after the 3rd recharge. The batteries that are still working hold charge nicely. Doesn't bode well for long term usage.

They arrived in excellent condition. I fully charged them and installed them my lanterns, and they work.

Bought a set of 8 batteries. One (1) battery was dead-on-arrival. Zero volts. Won't take a charge. Can't do much with an odd number of batteries. I mean, come on, man! how do you screw-up batteries?
