Excellent performance and super-fast charging.
I am very satisfied with this pack of RayHom rechargeable AA batteries. I use them for controllers, toys, and cameras, and the battery life is excellent. They charge quite quickly, and the 8-slot charger is very convenient because I can charge everything at the same time. The quality feels very good, and they maintain a constant power output—unlike others that drain quickly. Furthermore, the carrying case is compact and looks sturdy. I use them for controllers, toys, and cameras, and the battery life is excellent. They charge quite quickly, and the 8-slot charger is very convenient because I can charge all of them simultaneously; plus, I can take them with me wherever I go.

The Ultimate "All-in-One" Charger for a Busy Household
If you’re like me and have a drawer full of different rechargeable batteries for everything from TV remotes to high-end cameras, you know the struggle of having five different chargers plugged in at once. This RayHom Smart Charger has been a total life-saver for my organization. Why this charger beats the cheap ones: Individual Charging Slots: This is the most important feature. You don’t have to charge batteries in pairs. If you only have one dead battery, you can pop it in any slot and it works. You can even mix and match AA and AAA sizes at the same time. Smart LED Indicators: The display is crystal clear. It shows exactly which batteries are still charging (Red) and which are ready to go (Green/Blue depending on your model). It even flashes if you accidentally put in a "bad" battery or a non-rechargeable one, which is a great safety feature. USB-C Input: I love that it uses a modern USB-C port. I can plug it into my phone brick, my laptop, or even a power bank while traveling. It’s much more convenient than the bulky wall-plug style chargers that block other outlets. Safety First: It doesn't get hot. It has built-in protection against overcharging and overheating, so I feel comfortable leaving it on the counter to finish its cycle overnight. A Pro Tip for Users: This charger is optimized for Ni-MH and Ni-CD batteries (and some versions support 1.5V Lithium—check your specific box!). If you’re using it for the RayHom Lithium batteries, they charge incredibly fast, usually in under 2-3 hours. The Verdict: It’s compact, intelligent, and handles a heavy workload without a hitch. It has turned my "battery chaos" into a streamlined system. If you want to extend the life of your rechargeable batteries, you need a smart charger like this that won't "cook" them with too much current.

Great product, highly recommended
These rechargeable AA lithium batteries provide a constant 1.5V output and long-lasting performance thanks to their 3400mWh capacity. They work very well in devices that require stable power. The 8-slot smart charger allows you to charge them all at once quickly and independently. They are a great investment because they last a long time and help save money.

Longevity
Charger case is very easy to store. A little disappointed in longevity of charge about 2-3 weeks, then they have to be charged again. Might try better quality battery. But overall am pleased with purchase

Excellent set
Excellent form factor: the charger doubles as a convenient storage and carrying case. It’s great that each battery can be charged independently - charge as few as one battery at a time. The batteries are very easy to insert or remove from the case. They have good battery life and feature li-ion chemistry. I tried them in a few different devices and flashlights were bright and long lasting. I haven’t heard of this RayHom brand before, but they seem to make quality rechargeable batteries.

Nice option.
Excellent charging power. The batteries have a capacity of 3400 mAh and come at a very good price. Another thing I really liked is how easily they fit into the charger, and the fact that you can literally charge them anywhere using a USB port.

Love it no need to throw out batteries
I finally made the switch to rechargeable and I don’t regret a thing! Works great and holds a charge for a long time

Not the battery capacity advertised (detailed test results included)
My main use for these batteries is for the Blink Outdoor 4 cameras, so need the batteries to have longevity and especially to get thru the winter when changing batteries in cold weather and snow can be more challenging and problematic. I wanted lithium batteries due to their consistent power output in cold weather, which alkaline and Ni-Nh decline significantly during the cold. I chose these batteries for the above reasons and also because of the high 3500 mWh (total energy a battery can store and deliver) so they'd last thru the winter without having to be swapped out. First, some terminology for consistency: • mWh stands for milliwatt-hours and represents the total energy a battery can store and deliver. • mAh stands for milliampere-hour and represents the battery's capacity, indicating how much electrical charge a battery can hold. These are packaged nicely with a well built charging box. However, they don't charge anywhere close to the 3500 mWh advertised on Amazon; closer to 1000 mWh less, which is a huge difference (see screenshots below). I used a XTAR VX4 Battery Capacity Tester and Charger, which you can get on Amazon. Lithium batteries discharge at a consistent 1.5V from beginning to end, even when the charge is very diminished near the end of its charge, so a regular battery tester doesn't work as it would show a battery as being consistently and fully charged until there was about 0% charge left (eg. a 20% charged battery would show as 100% fully charged). This tester determines the mAh and the mWh by first fully charging the battery(s), then fully discharging them (the battery levels are determined here), then fully charging them again so you can use them (C-D-C). The mAh is not provided on Amazon's website, so I calculated it using the standard formula of mAh = mWh divided by the battery volts. So, 2266 (mAh) = 3400 (mWh on website) / 1.5 (battery's volts). Upon testing of all 12 batteries shipped, the mAh averaged about 1699 vs. the 2266 it was supposed to be, so a lot less. The mWh averaged 2552 vs. the 3500 it was supposed to be, again far lower than advertised. I included screenshots of all test results below (mAh and mWh are in separate screenshots). When I first saw the test results, I thought it was just a few of them perhaps defective, but all 12 tested in the same range, so that doesn't look like a defect but more like false advertising. The Energizer Ultimate Lithium AA Batteries (non-rechargeable) has an advertised mAh of 3500, which equates to a mWh of 5250 (mWh = mAh x 1.5 volts), far superior to these rechargeable. The cost savings of using rechargeables may be good, but battery performance is more important to me, so the Energizer one-time use are the way to go. Obviously, I've returned these. I've reviewed several other rechargeable Li-Ion batteries below, none that charge close to their advertised capacities: My XTAR Lithium (Li-Ion) AA Battery Review: https://www.amazon.com/gp/customer-reviews/RSUM0LDFT2FPX My SincehHoly Lithium (Li-Ion) AA Battery Review: https://www.amazon.com/gp/customer-reviews/R390K7RXXBV8VN My Delgeo Lithium (Li-Ion) AA Battery Review: https://www.amazon.com/gp/customer-reviews/R2OPXD8DHSCY37 My XTAR VX4 Charger & Battery Capacity Tester Review: https://www.amazon.com/gp/customer-reviews/RXTAHAOCCR0F5
