Bill K: I bought these for my ring path lights they take 4 D batteries. It was costing too much for batteries. I use rechargeables for the lights inside my utility trailer so I got these for the outside lights. They seem to be lasting a long time between charges and I don’t see a difference in the brightness. So far it looks like a good buy

びんた: 容量が大きいのと値段が安いのとで購入しました。
問題なく充電でき、使用できてます。
凸部に紙っぽいシールで本体を覆っていて、こんなんで大丈夫かと思いましたが、某国産の単一電池も
同じ様な感じだったので、問題ないんでしょうね。
液漏れがない（しにくい？）ので非常用の懐中電灯に使用していますが、一度の充電でどこまで持つの
かは、これから検証です。

R. Wood: First, the bad news...My initial experience was not positive. Six of the eight BONAI D batteries I purchased would not charge. After about 10 seconds, the BONAI charger displayed an error message. I really wasn't sure whether the problem was the batteries or the charger.

Now the good news... BONAI customer support is superb! I communicated with them several times via email as they attempted to solve the problem. They responded promptly (within several hours during the work week...and very early Monday morning when I emailed over the weekend.) Pretty quickly the tech determined that the batteries were bad and sent me eight new ones. They arrived on the second business day.

The replacement batteries charged without issue. Having said that, buyers should know that it takes a very long time to charge these batteries. Here is what the support tech wrote me in one of the emails:

"The higher the battery capacity, the longer the charging time. The capacity of this battery is 10,000 mAh. When charging one battery, the charging current is 2,000 mAh, and it can be fully charged in about 11 hours. When charging 4 batteries at the same time, the current of a single slot is...

Jason Trador: I have Ring Pathway Lights around my house that are activated by motion. The lights take 4 D batteries, initially I purchased the EBL batteries. Half of the EBL would not ever recharge and each time I needed to recharge the batteries that would take a charge without getting an error message right at half would not charge. I was extremely disappointed with the batteries so I tried the Amazon Basics Rechargeable D batteries and had the same exact issue. Out of 8 batteries only 4 would actually recharge then when it was time to charge the batteries again right at 50% of them ended with error messages. I absolutely love the Ring Lights and what they do for the curb appeal for my home so I decided to try one more brand before changing up the lights and I bought these Bonai D batteries. I'm totally blown away with the performance of these batteries, every single one of the batteries has been recharged several times and they all work perfectly. I did not have much hope for the 16 Ring Pathway Lights that take 4 and these Bonai cost double what EBL and Amazon Basics cost but these work and the others do not compare to these Bonai batteries. These are a must have for anyone that uses...

Michaelskyrider: These seem to be great batteries so far. There is a mysterious but consistent event that took place with every single cell when I charged them. The indicators on the Charger displays reached 3 bars, but never 4, which indicates a full charge. I am using a pair of brand new EBL-C9036W chargers and both did the same thing. I left the batteries charging all night thinking that maybe the charging amperage was not what the specs indicated. As it turns out, as far as I can tell, the chargers are working as they should, but the battery indicators were still flashing at 3 bars instead of a solid 4 the next morning. The batteries were almost hot to the touch, but not a dangerous hot by any means, so I unplugged the chargers and installed the batteries in some older, portable fluorescent lanterns. They seem to be undamaged, work great and so far have outlasted any other batteries I have ever used in these lights, including top of the line disposable alkalines. So on to my point and theory. I think each cell has a thermistor installed as a safety device to prevent over charging in the event that someone were to charge them in a manual charger as apposed to a smart charger. When the batteries...
