D Batteries Rechargeable 4 Pack with4 in 1 USBC Charging Cable D Size Cell Lithium Batteries 7500mWh 1.5V for Flashlights, Toys, and Floodlights

I like them, although they won't charge in a regular battery charger. You have to use either c-cable that is provided or your own. They charge pretty fast.

I was skeptical at first but these batteries have held their charge and have performed very well. Recharging is a breeze, just plug them in, no need for a separate charging dock/station. Good value, appears to be good quality materials, easy to use and overall good value over buying non Rechargeable batteries.

Arrived on time and works very well.

I've been using these batteries in my outdoor motion light. They last a long time before needing a recharge and it's nice not to have to throw away batteries anymore. The first set has been working so well that I bought three more packs but I was disappointed when two batteries didn't seem to be working when I went to charge them. The green indicator on the end didn't light up like they did on all the rest. I put the two questionable batteries in a flashlight and they worked just fine. After a few hours I put them on the charger and the indicator lights up now. So, if you get a battery where the indicator doesn't light up, it may not be defective. Try using the battery before charging it.

Had to use them a little first so I could fully charge them. Work exceptionally well. I use them in the Einstein Ocean Soother & they are lasting a long time. Usually the Einstein eats C-Batteries, so I am super thrilled with how they are doing.

These batteries do not hold a charge after only a few uses. I bought them for my son's mobile he can't sleep without and these batteries worked great tge 1st 2 times. They didn't hold a charge as long as regular batteries but I was ok with that. Around the 3rd time charging them they stopped holding a charge at all. I put them in and 5 min later my kid us crying because they stopped working. Don't waste your money

Premium equipment for less $ ! No more crappy NiMh.

These are great and easy to recharge. The are a lighter weight than standard C batteries, too!
