Rechargeable AAA batteries ESPERANZA EZA101B — HR03 1000 mAh, pack of 2

Rechargeable AAA batteries ESPERANZA EZA101B (HR03) provide a reusable power source with a nominal capacity of 1000 mAh and a nominal voltage of 1.2 V. Supplied as a pack of 2 cells in blister packaging, these Ni‑MH batteries are designed to replace single‑use alkaline AAA batteries in compact electronic devices. The cell chemistry and manufacturing process reduce self‑discharge so that a stored battery retains approximately 85% of its nominal capacity after one year. The cells support around 1000 charge cycles when used and charged according to manufacturer recommendations and are compatible with chargers intended for Ni‑MH rechargeable batteries.

Advantages

These ESPERANZA Ni‑MH AAA batteries combine the reusable nature of rechargeable cells with performance characteristics close to those of alkaline batteries for many low‑to‑medium drain devices. Reduced self‑discharge, long cycle life and compatibility with standard Ni‑MH chargers make them a cost‑effective and environmentally preferable alternative to disposable batteries. The blister pack of two cells is convenient for immediate replacement of depleted AAA batteries in household electronics.

How to use

Insert the batteries into the device matching the polarity markings (+/−). Charge the cells only using a charger designed for Ni‑MH rechargeable batteries and follow the charger manufacturer’s instructions. For new cells, perform a full initial charge before first use. Avoid leaving batteries in devices that are unused for long periods; if storage is required, keep them in a cool, dry place and observe polarity when storing multiple cells together.

Usage recommendations

To maximize service life and performance, use a smart charger with temperature and charge‑termination control and avoid overcharging. For devices with very low continuous drain, periodically recharge the cells to maintain capacity. Dispose of damaged or end‑of‑life Ni‑MH batteries according to local recycling regulations.
