Product Description

Features

High Energy Density: Offers one of the highest capacities available for a standard AA rechargeable cell, enabling extended device runtime.
Robust & Safe Chemistry: Ni-MH is inherently stable and contains no toxic heavy metals like cadmium (Cd), making it an environmentally friendly choice. It is more resistant to leakage than alkaline batteries under normal use.
Excellent High-Drain Performance: Capable of delivering high currents, making it suitable for power-hungry devices such as digital cameras and motorized toys, where alkaline batteries often fail prematurely.
Wide Operating Window: Performs reliably in a broad range of environmental conditions.

Use a Smart Ni-MH Charger: ALWAYS use a quality charger specifically designed for Ni-MH chemistry. It must feature -ΔV (negative delta voltage) detection and/or temperature monitoring to terminate the charge accurately and prevent dangerous overcharging.
Avoid Dumb/Trickle Chargers: Do not use simple, timer-based or indefinite trickle chargers, as they can overcharge and damage high-capacity cells.
Charge in a Safe Environment: Charge in a well-ventilated area on a non-flammable surface. Do not cover the charger or batteries while charging.

Avoid Deep Discharge: While tolerant, consistently discharging below 1.0V per cell will shorten lifespan. For best results, recharge batteries when device performance drops.
Use in Matched Sets: When using multiple cells in a device, they must be of the same brand, model, age, and charge state. Never mix old and new batteries or different chemistries.
Allow Cooling: After heavy use or fast charging, let the cells cool to near room temperature before recharging or storing.

Storage

Optimal Storage Charge: For long-term storage (>1 month), store cells at a 40-60% state of charge (open-circuit voltage ~1.25V - 1.30V). Storing them fully charged increases performance loss.
Pre-Charge after Storage: After prolonged storage, a “refreshing” charge/discharge cycle may be needed to restore full capacity.
Physical Care: Do not puncture, crush, deform, or expose to fire. Keep terminals clean and free of debris.
