AAA Rechargeable Batteries

Rechargeable AAA batteries or triple A batteries are one of the most common types of standard battery sizes, suited to compact, low-drain electronics such as remote controls and clocks. These have the same standard AAA size and shape, with the added benefit of being rechargeable, replacing single-use cells in devices that see regular use.

Our range of rechargeable AAA batteries includes popular brands such as Energizer, Duracell, Ansmann, RS PRO, Panasonic and Eneloop, spanning consumer, commercial, and industrial needs. If you need single-use cells instead, browse our non-rechargeable AAA batteries range.

AAA Battery Specifications and Chemistry

Rechargeable AAA cells use nickel-metal hydride (NiMH) chemistry, carrying the international designation IEC-HR03 and a nominal voltage of 1.2V per cell. Unlike the older nickel-cadmium (NiCd) cells they replaced, NiMH batteries contain no toxic cadmium and show minimal memory effect, so they can be recharged at any state of charge.

To the IEC standard, an AAA cell measures 10.5mm in diameter and 44.5mm in length, keeping it dimensionally consistent with standard AAA device compartments. Rated capacity across the RS range runs from roughly 550mAh to 1,000mAh, giving buyers a choice between lighter weight and longer runtime.

Rechargeable AAA NiMH batteries are designed to operate reliably across a wide range of temperatures, making them suitable for industrial and outdoor applications. Depending on the model, cells in the RS range are rated for operating temperatures from -20°C to 50-65°C. Use the Operating Temperature filter to identify batteries that meet the environmental requirements of your application.

Standard vs Low Self Discharge (LSD) NiMH Batteries

One of the most important selection criteria is whether a cell is standard NiMH or Low Self Discharge (LSD) NiMH. The difference is how quickly a AAA battery loses charge while sitting unused.

Standard NiMH cells self-discharge quickly and can be near-empty within two to three months of storage, which suits devices you use and recharge regularly. LSD NiMH cells, such as the Eneloop and Ansmann MaxE ranges stocked by RS, hold their charge far longer, retaining roughly 75% to 80% after three years at room temperature. That makes them a strong fit for equipment that sits idle between uses, including torches, first aid and emergency kit, TV remotes, and seasonal devices.

The trade-off is capacity: LSD cells typically carry a lower rated capacity than the highest-capacity standard cells, though this is rarely noticeable in low-drain use.

What Are AAA Rechargeable Batteries Used For?

In everyday use, rechargeable AAA batteries power the same compact, low-drain electronics as their disposable counterparts. Typical applications include TV and appliance remote controls, digital cameras, MP3 and portable audio players, battery-powered lights, wireless doorbells, and clocks. Their small form factor makes them a default choice wherever a device is lightweight and draws modest current over long periods.

Beyond retail replacement use, RS also stocks rechargeable AAA cells with different termination types. Alongside standard button-top cells, the Termination Type filter on this page lists flat-terminal and solder-tag (tagged) versions, built for professional battery pack assembly and integration into finished products rather than drop-in replacement alone.

Industrial and Commercial Applications of AAA Rechargeable Batteries

Rechargeable AAA batteries also serve a broad range of commercial and industrial roles, from field equipment to standby safety systems.

Professional and Industrial Devices

NiMH AAA cells are widely assembled into custom battery packs fitted with protection circuitry and thermal sensors, powering equipment that needs both endurance and high-current bursts. Rugged pack construction lets them handle vibration, shock, and temperature fluctuation, which is why they suit handheld and field devices, diagnostic equipment, and backup power units in industrial settings.

Facilities and Safety Equipment

The same chemistry underpins emergency and standby systems. Deep-cycle NiMH cells are engineered for emergency lighting, delivering steady low-level current over extended run times and holding charge through long idle periods. This suits exit and emergency lighting and other standby safety equipment that may sit unused for months but must activate instantly during an outage.

Consumer and Household Electronics

There is also a consumer segment for rechargeable AAA batteries, covering remote controls, cameras, and toys. The RS range reflects this with consumer-facing brands such as Energizer and Duracell alongside its industrial lines.
