10 Best Rechargeable Batteries 2025 in the United States

The Amazon Basics NiMH Rechargeable Batteries bundle offers a convenient package with 4 AA (2000mAh) and 4 AAA (800mAh) batteries plus a 4-bay charger designed specifically for NiMH batteries. These batteries come pre-charged and can be reused up to 1000 times, providing excellent long-term savings and reducing waste. They retain about 80% of their charge after 12 months of storage, making them suitable for devices that aren’t used daily. The charger is user-friendly with LED indicators to show charging status and errors, and it prevents overcharging by switching to trickle charge when batteries are full.

Charging times are reasonable—around 3.5 hours for 2 AA batteries and 7 hours for 4 AA batteries—so you won’t have to wait long to reuse them. The charger also features a foldable plug, making it easy to carry when traveling. NiMH batteries have a voltage of 1.2V, slightly lower than alkaline batteries (1.5V), which can sometimes result in shorter device runtime. Additionally, NiMH batteries are a bit larger than alkalines, so it’s important to check your device compatibility. The charger only works with NiMH batteries and shouldn’t be used with other types like lithium-ion or NiZn.

This bundle is well-suited for anyone looking for a reliable, cost-effective rechargeable battery option for everyday household devices like remotes, toys, or wireless keyboards, especially if you prefer a safe and smart charging solution. If longer runtime per charge or higher voltage is needed, other battery types might be more appropriate.

The Amazon Basics 4-Bay Battery Charger is a convenient option for anyone looking to recharge AA and AAA NiMH batteries. The included 4-pack of AA batteries has a decent capacity of 2000mAh and can be recharged up to 1000 times, making them a cost-effective and environmentally friendly choice. The charger is user-friendly with its plug-and-play design and LED indicators that let you know the charging status and if there are any errors like a defective battery.

It's also safe to use with features like wrong polarity detection, overheating prevention, and overcharge protection. The low self-discharge rate means these batteries can hold up to 80% of their charge for up to 12 months, which is great for occasional use. However, the charging time is relatively slow, taking about 7 hours to fully charge 4 AA batteries. This might be a drawback if you need your batteries ready quickly.

The travel-friendly design with a foldable plug is a nice touch for those who need to charge on the go. This product is solid for general household use, especially for those who use AA and AAA batteries frequently.

The Amazon Basics 24-pack AA rechargeable batteries offer a solid choice for everyday devices like remote controls, flashlights, and clocks. With a capacity of 2000 mAh and a NiMH (Nickel-Metal Hydride) battery type, they provide reliable power with a standard voltage of 1.2V, which is slightly lower than typical alkaline batteries but usually compatible with most household electronics. One of their biggest strengths is the ability to recharge up to 1000 times, making them cost-effective and environmentally friendly over time.

These batteries have a low self-discharge rate, holding about 80% of their charge for up to two years, so they stay ready longer when not in use. They also come pre-charged and have a shelf-life of up to five years, which is convenient for immediate use or emergency storage. However, because NiMH batteries are a bit larger than alkaline ones, it's worth checking that they fit properly in your devices.

There can be a shorter runtime in some devices compared to 1.5V alkaline batteries due to the slightly lower voltage. Also, it’s important to use a charger designed specifically for NiMH batteries to avoid damage or leakage, and to avoid mixing these rechargeable batteries with non-rechargeable or batteries of different capacities or ages. These batteries are well-suited for anyone looking for a reliable, reusable power source for common household gadgets and who values long-term savings and environmental benefits. Keeping in mind the voltage and device compatibility tips will help achieve the best performance.
