Based on hours of hands-on testing, the Energizer Recharge Universal AAs (available at Amazon) are our top pick. They provide the best balance of capacity and price, holding about 2,200 mAh of charge and supporting up to 1,000 charge cycles.
The Panasonic Eneloop Pro rechargeable battery pack is the perfect starter kit for those in need of rechargeable batteries. Not only are they some of the best batteries available on the market, but this kit comes with AA, AAA, and C and D cell batteries and a charger at a really good price.
So, when you need to stock up on batteries, we recommend getting one of our top picks. Our best overall rechargeable battery choice is the Panasonic Pro rechargeable battery due to its high capacity, variety of battery types, and excellent product quality. The following rechargeable batteries are all top-notch and available in AA and AAA models.
Standard size single-use batteries usually have a nominal voltage of 1.5 volts whilst rechargeable batteries are 1.2 volts. The exception being PP3 9 volt block size battery, and some specialist security batteries, which can be higher depending on the size and type of battery. As single-use batteries are consumed, the voltage reduces.
If the cordless phone is used for long periods of time choose a rechargeable battery with a higher capacity and if the phone is used for frequent short calls then replaced in the charger, a low capacity battery (400 – 600 mAh) will be sufficient.
The two most common types of rechargeable batteries are nickel-metal hydride (NiMH) and lithium ion (Li-ion). NiMH batteries have a voltage output of 1.2V and tend to have a higher capacity — measured in milliampere hours (mAh), a measure of how much electrical charge they can store.
Nearly every rechargeable power bank you can buy (and most portable devices) contain a lithium-ion battery. These beat other current battery types in terms of size-to-charge capacity, and have even increased in energy density by eight fold in the past 14 years.

You can immediately see that the high capacity 200Ah cell produces a minimum pack capacity ~138kWh at ~800V. The increments in pack capacity are also 138kWh. The small 5Ah cell allows a more granular approach to pack sizes, the downside is the number of cells that are used and hence the complexity of items such as the busbars.

A single NiMH battery has a nominal voltage of 1.2V, while a single lithium-ion battery is typically 3.6V. This means you can''t directly replace a NiMH battery with a lithium-ion battery of the same size, as the voltages are incompatible. You would need to use multiple lithium-ion cells in series to match the voltage of the NiMH battery pack.
The 18650 battery capacity range typically falls within approximately 1000mAh to 3500mAh, with exceptions for specialty or high-capacity batteries. High capacity 18650 batteries are generally more expensive than low capacity options due to their increased energy storage capabilities.
But if you''re looking for a great lithium-ion rechargeable battery, these 1.5-volt Tenavolts have a capacity comparable to NiMH batteries—about 1,848 mAh—with a charging time of under two hours. They''re rated for about 1,000 cycles, and reviewers say they maintain their output for years with proper care. They come in packs of two, four, or 20, with or without …
We would recommend a low-mid range capacity rechargeable battery for cordless phones (for AAA size batteries a capacity of around 400 mAh to 800 mAh). The capacity of a rechargeable battery in a cordless phone does not need to be high as it only effects the time between charges and usually cordless phones are replaced in the charger when not in ...
