Rechargeable battery Esperanza EZA104R
The Rechargeable battery Esperanza EZA104R is a pack of four AA NiMH cells designed for repeated use in everyday portable electronics. With a nominal voltage of 1.2 V and optimized cell chemistry, these rechargeable batteries combine the convenience of AA format with Nickel‑Metal Hydride technology to deliver stable power for devices such as cameras, remote controls and toys. The EZA104R cells are manufactured with reduced self-discharge characteristics, retaining approximately 85% of nominal capacity after one year of storage, which supports longer shelf life and reliable readiness for reuse.
Esperanza EZA104R batteries use NiMH chemistry to provide a balance of energy density, rechargeability and environmental benefits compared with single‑use alkaline cells. The pack of four AA batteries offers repeated recharge cycles that reduce overall cost of ownership and lower waste. Optimized cell construction minimizes self‑discharge, maintaining most of the stored energy during storage and between uses. These characteristics make the cells suitable for frequent application and help decrease the environmental impact associated with disposable batteries.
Insert the AA NiMH cells into the device ensuring correct polarity. Charge the batteries before first use with a compatible NiMH battery charger that supports AA cells and follow the charger's instructions for charging times and indication lights. Avoid mixing these rechargeable cells with non‑rechargeable batteries or with cells of different capacities or states of charge. After use, recharge the batteries as needed; do not exceed the recommended charging method provided by the charger manufacturer.
To maintain optimal performance, store the batteries in a cool, dry place and recharge them every few months if left unused. Use a charger designed for NiMH chemistry and stop charging when the charger indicates completion. Replace batteries as a set to ensure balanced performance in multi‑cell devices.
