Granicell AAA NiMH Rechargeable Batteries, 1100mAh, 24 Pack

These Granicell Rechargeable AAA batteries come in a 24‑pack and are currently priced at £17.49 from £19.99. They use NiMH chemistry with a nominal voltage of 1.2V and a capacity of 1100mAh, intended as a reusable alternative to single‑use cells.

• Capacity & shelf life: 1100mAh; manufacturer states around 80% capacity retention after three years in storage.
• Stable output: designed to provide a steady ~1.2V output to help protect devices from unstable voltages.
• Rechargeability: rated for approximately 1,300 recharges, which the maker compares to the equivalent usage of roughly 2,000 disposable lithium batteries.
• Compatibility & conditions: suitable for most 1–1.5V devices (remote controls, gamepads, alarm clocks, mice, toys, etc.) and rated to operate between −40°C and 140°C.
• Environmental & readiness: described as free from lead, cadmium and mercury and supplied pre‑charged (manufacturer notes wind energy was used), so they’re ready to use out of the box.

Pack size: 24 AAA cells.
