3 Section 5 - Health Hazard Data Human Hazards A Sealed Nickel-Metal hydride cell is not hazardous to humans in normal use. Threshold Limit Value (TLV) and Source: N/A Physical Nickel plated steel does not present any risk providing the cells are used for their intended purpose and according to valid directions for use. Chemical In normal use there is no chemical risk. Should the battery be misused (abusive overcharge, reverse charge, external short circuit etc.) some electrolyte may leak from the cell through the safety vent. See Section 6 below for suggested action. Ingestion Ingestion – If...

5 Section 9 – Precautions for Use, Handling and Storage Storage Store in a cool place, but prevent condensation on cell or battery terminals. Elevated temperatures may result in reduced battery life. Storage temperatures should be within the range of 40°F (5°C) to 77°F (25°C) in a 65 +/- relative humidity. Handling Accidental short circuit will result in high temperature elevation to the battery as well as shorten the battery life. Avoid prolonged short circuit as the heat generated can burn the attendant skin and even rupture the battery cell case. Batteries packaged in bulk containers should...
