Note:
For a longer battery life, observe the following items:
• Place the batteries in a dark, cool place.
• Keep the room temperature within the range of 10°C to 35°C (40°F to 85°F).
• Floating voltage must be kept within the range of the battery specification at all times.
• After discharging, perform equalized charging as per the battery specification.
Check the load voltage (DC –48V ±5 V) of the rectifier.
Check the batteries. Check the forced-charge voltage and floating
voltage.
Check the specific gravity, liquid level and
rated capacity of each battery.
