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

These rechargeable batteries are a total game-changer! No more buying disposables—they charge super fast (about an hour) right from my laptop or car charger. They last way longer in my flashlight, remote, and kid’s toys compared to regular batteries. The charging lights make it foolproof, and knowing I can reuse them for years saves money and hassle. Perfect for anyone tired of dead batteries!

This rechargeable AAA battery works great for the toys. It is very easy to charge through the type C cables. The battery lasts a very long time. The size fits well. Good value for money.

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.

A very handy item to have when you need batteries for a light. Saves a lot of money on buying replacements for dead batteries in things like mini-flashlights. The built in plug makes recharging easy. Also good for the environment as you throw away far fewer batteries.

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.

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.

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.

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