Duracell 203815 household battery Rechargeable battery AAA Nickel-Metal Hydride (NiMH)

Duracell Recharge Ultra AAA Nickel-Metal Hydride (NiMH) rechargeable batteries provide reliable, replaceable power for a wide range of portable devices. These AAA-size cells use NiMH chemistry to deliver steady voltage and are supplied as a pack of two. They are designed for repeated recharge cycles, reducing the need for single-use batteries and supporting everyday devices that demand consistent energy output.

Advantages

These rechargeable batteries offer a balance of capacity and rechargeability suitable for frequent use. NiMH chemistry ensures low self-discharge compared with older rechargeable types, while maintaining stable performance in high-drain devices. As AAA cells in a two-piece pack, they fit common battery compartments and are compatible with standard NiMH chargers. The design emphasizes durability across many charge/discharge cycles, supporting sustainable use and lowering long-term operating costs compared with disposable batteries.

Suitable for

• Wireless computer peripherals such as mice and keyboards
• Portable audio players, MP3 players and small radios
• TV remotes, game controllers and digital cameras
• Battery-powered toys and LED flashlights
• Household measuring devices and small medical devices that accept AAA cells

Key specifications

• Battery type: Rechargeable AAA cell
• Battery chemistry: Nickel-Metal Hydride (NiMH)
• Quantity in pack: 2 pieces
• Form factor: AAA
• Intended use: High-drain and everyday devices compatible with AAA NiMH cells

How to use

Insert the Duracell Recharge Ultra AAA batteries into the device following the polarity markings. Charge the batteries before first use and recharge as needed using a charger designed for NiMH AAA cells. For best results, avoid mixing these rechargeable cells with non-rechargeable batteries or cells of different capacities in the same device. When charging, follow the instructions of your charger regarding charge time and indication lights to prevent overcharging.

Recommendations

For optimal lifespan, store charged batteries at moderate temperatures and recharge them before prolonged storage. Use a dedicated NiMH-compatible charger and recharge the cells regularly if used in high-drain devices; replace the batteries when their runtime noticeably decreases after many charge cycles.
