1. STORING

• Keep battery in cool and dry place.
• Do not remove aluminum foil seals on cover nor fill electrolyte.

2. USING

• Fill each cell of battery with dilute sulfuric acid 1.25 specific gravity (at 200C) up to Upper level. Wait in 20 minutes, if the electrolyte level drops down, refilling battery with
• the same electrolyte to reach the Upper level.
• Keep the electrolyte level between Upper and Lower level. If electrolyte level is lower,
• please add pure water to restore to “Upper level”. Only add with pure water, do not use acid solution.

3. MAINTENANCE

• Use a rectified direct current (DC). Connecting the battery (+.-) terminals respectively to (+,-) poles of DC source.
• Charging current is about 1/10 of battery capacity.
• For example, N20 battery with capacity of 20 Ah is charged with the current of 2.0 amperes.
• Unscrew all vent plugs when charging.
• If battery is unused for a long time after filling electrolyte, battery must be fully charged every month.

4. SAFETY IN USING

• During charging, battery may produce explosive gases. Do not charge near flames, smoking or sparks.
• If electrolyte contacts your skins and eyes, flush with water immediately.
• Check that all cable connectors to the terminals are properly tightened; connections that are too tight or too loose could result in post breakage, meltdown or fire.
• To avoid short circuits do not lay objects on top of battery.
• Charge battery in a well-ventilated area.
