EBL D Cells 10000mAh Rechargeable Batteries (4 Counts) with C D 9V AA AAA Battery Charger

Works well. I like that you can see how each individual battery is charging as opposed to some other chargers. Also nice to have the discharge feature to ensure you're getting a full charge and not building up "charging memory".

Great product, dual power so it also works on 220V, easy usage.

I love these rechargeable batteries. It's easy, cost-effective, and they last quite a while.

Gets the job done but my god it’s ugly, keeping it in the garage. Luckily not much takes D batteries anymore but for those things that do, definitely grab some of these. D batteries usually cost around $2 each at the store so you can do the math if it makes sense to get the recharging variety for your case.

The batteries and charger seemed to be well made. The batteries charged up in 3 to 4 hours. They are now in service at my home and only time will tell how long they last.

Works as it should

Very nice

I took a risk that perhaps the 1-star reviews were flukes, thinking that a lot of people had rated this product with 5 stars for a reason. I regret that now. A few notes:1) The charger's instructions are incorrect: when the batteries are being charged, the light indicator FLASHES. According to the scant instructions in the booklet, this should mean that there is a problem and that we need to stop charging the batteries right away. Pushing the blue button, as another reviewer suggested, only puts the charger in DISCHARGE mode charge the batteries. So put in the batteries, and let them charge for... about 5 hours (in my case). The battery icons will slowly start showing 2 bars, and then 3.2) I charged the 4 (D) batteries and immediately used 2 batteries in a mini fan that I keep on my bed at night. The first set of batteries lasted about 3 nights. For reference, non rechargeable alkaline D cell batteries usually lasted about 10 to 13 nights for me.3) On the 4th night, I replaced the batteries with the 2nd set of D batteries that I had charged at the same time. Those only lasted 1 night. Conclusion: the batteries not only don't last much at all, but they also do not hold a charge very long, even if they are not being used.4) As I used the 2nd set of batteries in my fan, I put the 1st set back in the charger to recharge them immediately. After just 2 seconds, the light indicator started to flash with an error message (first photo)! It also showed one battery was still fully charged, which it wasn't at all as both batteries were almost depleted. I made sure that the batteries were inserted properly (they were) and tried it again. Same problem. I moved the batteries in different spots in the charger (2nd photo) and this time the icons indicated that the batteries were depleted, and this time they charged (it took about 5 hours to charge 2 batteries). For the record, this was only the SECOND TIME that I had used the charger!5) It is also to be noted that the plastic cases that come with the charger to hold the batteries are poorly designed in that it is EXTREMELY hard to open the cases. I had to pry mine with a blade in order to be able to get to the batteries! It's very irritating.CONCLUSION: I deeply regret having bought this shoddy product. If you think "I'll take the risk", as I did, you'll end up writing your own 1-star review and regretting the purchase and wasted money. Don't buy this.
