Rechargeable AA batteries ESPERANZA EZA102G 1000mAh NiMH 4-pack

Rechargeable AA batteries ESPERANZA EZA102G are Ni-MH cells with 1000 mAh capacity and 1.2 V nominal voltage supplied in a pack of 4. These AA (sometimes labelled HR03/size AA) rechargeable batteries are intended to replace single‑use alkaline cells in everyday devices, offering lower environmental impact and long-term cost savings. The cells are manufactured to limit self-discharge and retain approximately 85% of nominal capacity after one year of storage; they are suitable for repeated charging up to about 1000 cycles.

Advantages

ESPERANZA EZA102G batteries combine modern nickel‑metal hydride technology with convenient performance similar to alkaline cells, delivering stable 1.2 V output and reduced self‑discharge. They are reusable for many charge cycles (about 1000), lower disposable battery waste, and can be charged in standard Ni‑MH chargers. Their design aims to balance capacity and longevity for everyday household use.

Suitable for

• Remote controls
• Toys and children's devices
• Flashlights and torches
• Wireless peripherals (keyboards, mice)
• Small household electronics

Do not mix these cells with non‑rechargeable batteries in the same device. For best results, charge all batteries in the pack together before first use.

Usage recommendations

Store batteries in a cool, dry place and avoid extreme temperatures. If batteries will not be used for long periods, recharge them before storage and check charge level periodically. Replace all batteries in a device at the same time to ensure balanced performance.
