BONAI Rechargeable C Batteries 5,000mAh 1.2V Ni-MH High Capacity High Rate C Size Battery C Cell Rechargeable Batteries (8 Pack)

I have so many devices that require batteries that I found myself in a battery replacement circle. Alkaline batteries seem to have a common problem of leaking and has ruined many of my best devices. As far as I know, rechargeable batteries don't leak. As least mine haven't . I bought the BONAI charger and batteries and they are great. Have replaced many of the old batteries with the BONAI ones. Sofar they have worked flawlessly. They have a much higher current capacity and should work a lot longer. When they need replacement, I just recharge the battery and I'm back in business. I like that. Now I don't have to run to the store for new batteries. True, they are a little more expensive than alkaline batteries but those are a one time use. Tired of sending batteries to the land fill.

My wife and I has a little girl who falls asleep to the little einsteins music box and we would go through normal batteries every week. With this it has saved us an astronomical amount of money with recharging. We let it run the entire week, and when we go out on Saturdays we let the batteries charge all day and when we get home they are good to go! If you have a baby or toddler this is a must!!

So i have a rechargeable emergency light kit for my car, and it takes c batteries. I figured getting rechargeable might be impossible. Well lo and behold, these batteries work. I have no clue about their battery life, but they punch out well enough to sustain a fluorescent bulb continuously for several hours, and it plugs into the wall to recharge.

For rechargeable batteries, these are decent for the price. I did notice a slight decrease in light output (compared to alkaline batteries), but nothing to complain about. 4 stars, because of unknown longevity. Otherwise they'd be a 5.

My daughter has a music box that she HAS to have to go to sleep (the under the sea Little Einstein one). When we first got it we were putting new batteries in at least every 2 weeks because it’s a high drain item and she uses the heck out of it. So I turned to the BONAI batteries and charger to help us save money. I have been charging and rotating these batteries about every 2 weeks for over a year now and they are still going strong. (Box takes 4 batteries at a time and purchased the 8 pack of C). They take about 6 hours to charge which doesn’t bother me as I let it does its thing overnight. 8/13/2018 was my original purchase and am back for more today (2/1/2020). Not because the first 8 are wore out, but because we now have another daughter that uses the same music box and need more sets in the rotation. Highly recommend!

El primer uso duro 1 mes (en velas). En el segundo duro 10 días. En el tercer uso dura apenas 24 horas. Es un fiasco

i order the batteries early and when to use them this xmas season for my train. i charged them and within a few minutes the train stopped working. I thought maybe it has discharge after long time no use.. I charged them again and retry.. the train worked for less then a minute. After my firdt review the company contacted me and told me the battery is a 1.2 V. Which means it can have the effect I explained with the xmas train. I did not know this and assume the battery was a 1.5V. so part was my fault.. Ibwill find another use forvthe batteries. Company try to compensate but I refuse as it was my fault and I live outside the US. will cost us both more..

All batteries came sealed and have a nice weight to them. So far they charged up fine and are working in my son's Xmas presents, they have lasted a while so far, so seem nice. I will monitor how they hold up over time, but these shoudl save a lot of money as time goes on.

充電することで、何回も使用出来るので安く感じます

LED懐中電灯用に購入しましたが、容量もあり長持ちし、充電を数回しましたが快適に使用できています。使い捨て電池に比べて環境にも優しいかと思っています。まぁ、充電に要する電力を火力発電でしていたらどうなのか？と突っ込まれるかもですが、少なくとも電池自体の廃棄量が削減できると言うところで許してください。

どうやら当たりを掴んだようで、壁掛けの電波時計にバッチリ使えています。アルカリ乾電池はいつの間にか液漏れしているので充電池を探していました。これで安心。

充電回数は大切

大容量でこの値段はお得感があります。 結構手荒く扱っていますが、劣化もなく品質も良いかと思います
