6. ELECTROLYTE LEAKAGE
6.1 Leakage on arrival at warehouse.
Leakage shall be checked with naked eye. No leakage shall be observed with the naked eye; and no bulging
exceeding the maximum dimensions shall result.
6.2 Leakage at room temperature
After storing for 12 months at 20 ±15°C, 65±20%RH, no leakage shall be observed with the naked eye; and no
bulging exceeding the maximum dimensions shall result.
6.3 Leakage at high temperature
Within thirty days of manufacture, the cell shall be stored for 30 days at 45±2°C and below 70% relative
humidity, no leakage shall be observed with the naked eye; and no bulging exceeding the maximum
dimensions shall result.
6.4 Leakage of over discharge
After loading with 620Ω continuously down to 0.8V at 20±2°C, 65±20%RH, no leakage shall be observed with
the naked eye; and no bulging exceeding the maximum dimensions shall result.
