Rechargeable AAA Batteries USB C 1200 mWh Triple AAA Rechargeable Battery 1.5V AAA Lithium Batteries with 4-in-1 Charging Cable and LED Charge Indicator, 4-Pack

Great product, work great, hold a good charge. I bought these because I have an old digital camera that devours AA batteries. Won't even turn on if you use regular alkaline. Put in a couple of these rechargeable AAs and it works like a boss.

Confess with a convenient 4 way charger. USBC connectors plug in at an angle due to the AAAs small size. Indicator light shows charging/charged. Haven't determined the battery life, but they recharge. So who cares as long as they aren't very short lived. Will try to post an update after I use them for a bit.

I haven't actually used these batteries yet, but there's a key thing to know about the Type C charging port -- you have to insert the charge plug at a slight angle. Trying to push it in perpendicantly to the battery doesn't work. Initially I thought that either the batteries or the charging cable were defective, but now that I know this, it's easy to plug them in.

These rechargeable AAA batteries are a fantastic deal! It comes with a handy charging cable which charges all 4 batteries at once and the light indicators make it easy to track progress. Great for the environment and my wallet, no more single-use waste. Highly recommend!

These rechargeable batteries are super easy to use and a great eco-friendly alternative to disposable ones. They charge quickly, hold power well, and are perfect for everyday devices like remotes, cameras, and game controllers. Reliable and convenient!

Bottom line, one was loose in my flashlight so I measured. Wikipedia says that an AAA battery should be 44.5mm long, these are not.The four batteries are 44.0, 44.2, 44.2 and 44.4 mm long. Besides all being slightly too short, the shortest of all three batteries does not make contact in a Black diamond flashlight. For something with a larger spring, this might not be an issue, but it's important to note that they do not meet specification for this battery type. In a device where multiple batteries were end to end, this shortage would be more likely to create an issue.In the photo you can see that it is clearly shorter than a name brand battery.

Bought for my remotes. Haven't used them yet, waiting for current ones to expire.

Not a lot of battery life. Recharge after Recharge after Recharge.
