So far these are great. They charge pretty fast and I haven't run any dead yet. Seem to be high quality.

Seems to be holding up. Didn't care for the caution. Do not over charge, do jot undercharge. Like I have control of that or just sitting here watching the things charge. I gotta say the kid light that stops blinking when fully charged is a nice touch.

They dont last very long after a full charge

I found these batteries not too long after I decided that I was done with NiMH batteries. Most of the NiMH batteries have become unusable after a short period of time. Comparing lithium batteries to NiMH, I have been much happier. There is no doubt that any rechargeable batteries are better for the environment than standard batteries, but lithium rechargeable batteries like these, are far superior for the environment and your wallet. I have not needed to recharge these yet and I’ve been using them far beyond the time I would have needed o recharge my now recycled, NiMH battery collection. I think these batteries are a pretty good value compared to others at this price point. The build of these batteries are very nice, I have not used many usb c rechargeable batteries before, but I cannot complain about the build quality at all. I have not seen any of the batteries leak or burst open, which I know can be a real concern with lithium batteries. No fires or explosions either. I have tested these on a couple of my Volcas and they seem to fit just fine and operate exactly as expected. I like these batteries very much and I expect to be buying more of these from this manufacture in the future. They have lasted for a surprisingly long time and I am very impressed. A very solid 5 stars.

These 4000mWh rechargeable lithium AA batteries are a fantastic upgrade from traditional rechargeables. The built-in USB-C charging port on each battery is a clever design choice, completely removing the need for a separate charger. Just plug them in directly, and they charge quickly and evenly. The capacity is impressive at 4000mWh, and they hold their charge well even after extended use. They work great in power-hungry devices like smart locks, remote controls, and toys, delivering steady performance without sudden drops in voltage. Durability also stands out — after multiple recharge cycles, they still perform like new. The convenience of charging them with any standard USB-C cable makes them perfect for travel or everyday household use. Overall, these batteries are efficient, reliable, and incredibly user-friendly. A smart, future-proof choice for anyone tired of juggling different chargers or constantly replacing disposable AAs.

I recently received to the VariCore rechargeable AA lithium-ion batteries, and I couldn't be happier with them. With a high capacity of 4000mWh and a constant 1.5V voltage, these batteries provide stable power for my high-drain devices like my camera and RC remotes. One of the best features is the USB-C charging design, which allows me to charge them easily with a 4 in 1 cable, no need for a separate charger or adapter. The batteries charge quickly and the LED indicator is a helpful touch to show when they're fully charged. With over 1200 cycles and no memory effect, these batteries are not only convenient but also a cost effective, saving me money on disposable batteries in the long run. Overall, the value and performance of these batteries make them a good value and investment for anyone looking to power their devices without blowing money on cheap disposables.

I am reviewing this item for free as an Amazon Vine reviewer. I've been wanting to test out some AA lithum batteries for a while so I jumped on the opportunity to test these. So far they have outlasted my traditional NiCad rechargeable 2500mah AA's in my kids toys. These work just like normal AA's. I am removing 1 star because of the charging cable must be used to charge these and you cannot use other type c cables to charge the batteries. This means you need to assure you have the supplied splitter cable. You can charge one battery at a time or any combination up to all 4. Time will tell how these hold up to repeated cycles, but so far I have used these for 4 charge cycles on remote control cars. I would say we get about 5-10 minutes of extra operating time on the RC car vs the 2500mah nicad's.
