Let's talk about the EBL Pack of 8 10000mAh Ni-MH D Cells Rechargeable Batteries. First off, the capacity is impressive – these bad boys promise to keep your devices running for a long time. I used them in a Maglite flashlight, and they delivered full brightness for a solid 24 hours before slowly dimming over the next 12 hours. That’s pretty darn good for rechargeables!

One thing I noticed right away is that they don’t come fully charged, despite the product description claiming otherwise. When I popped them into my advanced charger (with individual cell controls), they took *hours* to reach full capacity. So, if you’re planning to use these right out of the box, think again—you’ll need to charge them first.

Now, here’s the catch: not all chargers play nice with these batteries. I tried using my trusty FC999 Mark III charger, and it flagged them as defective. Turns out, some chargers struggle with high-capacity batteries like these. EBL’s customer service was stellar—they even offered to replace them for free—but it’s something to keep in mind if you don’t have a compatible charger.

On the plus side, these batteries hold their charge well over time. I stored some in a caddy for a month, and they still had plenty of juice left. They’re also versatile—great for everything from flashlights to remote controls. The included plastic cases are handy for storage too.

The bottom line? These are solid rechargeable batteries with great longevity and performance, but make sure you have the right charger to go with them. If you do, they’re a fantastic investment for cutting down on disposable battery waste.
