Great charger!
I’m very happy with this charger. It works reliably and charges my AA batteries surprisingly fast compared to my old one. I also appreciate that it’s not limited to Amazon Basics batteries, it charges my Duracell rechargeables with no issues at all. The included batteries hold a good amount of power and perform well in everyday devices. Overall, it’s a great, practical set for anyone looking for affordable and efficient rechargeable batteries. Highly recommended.

Well impressed.
Having now largely gone over to rechargeable batteries we were looking for a new charger. The old one by a well known manufacturer charged slowly, the batteries got very hot and we needed to pick a time where we’d be around to turn it off when it had charged them. This on the other hand charges both AA and AAA batteries quickly, has an automatic turn off when the charging is complete and even indicates when a battery has failed. It’s small and compact and therefore easy to store. So far we are very impressed and would definitely recommend it.

Quality, convenience
Another Amazon product that works great at an affordable price. Recommend this over buying constant batteries and having to dispose of them. Great price. Direct wall plug in.

Useful status display above each battery
I like the display above each charging battery giving the status. I was able to sort out old rechargeable batteries that were in need of replacing. A good set of batteries recharged at a good speed and there was no guesswork when to stop charging as there was in a previous charger that had no display. It is possible to charge 1 or 2 batteries at a time without the need of filling the other spaces to make the charger work.

AAA batteries (don’t) do charge.
Update: 04/11/2025 Have tried again and after a number of attempts I accept that this charger does charge AAA batteries - hence the update. ========== Purchased to recharge AAA rechargeable batteries. Batteries won’t charge. Reason: +ve and -ve terminals won’t both connect to the charging points due to the shape of the battery chamber. May be ok for AA batteries but untried hence the 3 stars

Usable but unclear.
It seems like a good product. Let down by the lack of clear instructions. The charger states that slow blinking lights means charging and fast blinking lights means there is a fault. It seems like there is only fast blinking lights and faster blinking lights in reality which will leave you looking for reassurance the product isn’t faulty. The blinking lights as a default indicator are obviously annoying. Perfectly functional but I’d recommend spending a bit more and get one with a clearer charging indicator.

The Amazon Basics Rechargeable NiMH Battery Kit with Bay Charger is one of those purchases that immediately proves its worth. From the moment you open the box, the engineering quality and thoughtful packaging stand out. Each battery is neatly organized, protected, and clearly labeled, and the charger itself is compact, sturdy, and built with a level of precision that feels far above the price point. The batteries are impressive in both feel and performance. The AA 2000mAh and AAA 800mAh cells have a solid construction with a clean finish and consistent weight—small indicators of well-made cells. Once charged, they deliver stable, long-lasting power that performs just as well as, and often better than, many of the more expensive name-brand rechargeable batteries on the market. Whether in high-drain devices like flashlights, controllers, and small electronics, or in lower-drain household items, the runtime is consistently strong. The charger is equally noteworthy. It operates quietly, gives clear visual indicators, and charges efficiently without overheating. The independent bay design ensures each battery gets exactly the charge it needs, extending long-term lifespan. This is a feature you typically see in higher-priced smart chargers, yet here it’s included at a surprisingly affordable cost. What makes this kit exceptional is the value. For the cost of a single pack of premium disposable batteries, you’re getting a full rechargeable system that pays for itself quickly. It’s a smart investment for anyone who uses battery-powered devices regularly—families, photographers, tech users, and anyone looking to reduce waste and recurring costs. Use-cases range from around-the-house electronics to camping gear, flashlights, kids’ toys, bike accessories, and backup emergency kits. The batteries hold their charge well in storage, making them ideal for both everyday use and preparedness. Pros • Strong engineering and solid overall build quality • Long-lasting charge with consistent performance • Smart, independent-bay charger prevents overcharging • Excellent value compared to premium rechargeable brands • Ideal for high- and low-drain devices alike Cons • None—this kit is a fantastic buy For anyone looking for reliable rechargeable power at a fair price, this Amazon Basics kit delivers professional-level performance and long-term savings that make it an easy recommendation.

Think about it go to Costco or BJ’s and buy a big pack of batteries on sale, was definitely not cheaper than buying AA&AAA rechargeable batteries with the charger. Always have them ready to go. I got batteries for the whole house anytime ready and charged. it was common sense just never thought of it.

This is a very good rechargeable battery. I just takes a couple hours to recharge the batteries now I don’t have to buy so many batteries.
