Review on 🔋 Tenergy High Drain Rechargeable NiMH Batteries Combo - AA AAA C and D Battery, 1.2V: 8-Pack 2500mAh AA Cells, 8-Pack 1000mAh AAA Cells, 4-Pack 5000mAh C Cells, and 4-Pack 10000mAh D Cell Batteries by Kathy Sabo

These batteries are good. I've been using them for a week or two now and can say that their capacity is better than the alkaline batteries I've used in the past. I'm in the process of using rechargeable NiMHs in everyday household items. But I've been using Li-ion vape batteries for years and I've learned from it that there are really cheap batteries out there. They are not! Rschunimagu. I don't know how they measure mAh, but I can say that the capacity of these batteries is better than non-rechargeable counterparts. They charge up to 1.3 volts and seem to stay there most of the time until they are almost completely dead. Simply put, when I put them in my cat toy, the toy doesn't slow down when the battery runs low, it just stops when the battery runs low. :p I just wish there were more than 4 D batteries in the pack, my flashlight needs 6 and I have 4.
