• Thermo-sealed Tamper-proof Lid to resist leakage and corrosion.
• Hi-tech grid holds the active material to ensure long life and optimum power
• Heavy-duty polypropylene Container which prevents leakage and offers complete protection to the plates against damange from knocks, vibrations and envoirnmental factors
• Inter-cell welding through partition wall results in  better cranking
• Use of dry charged plates helps in Quick Initial charging

• All Series batteries are in Dry Charged condition.
• The dry charged battery is activated instanteously without initial charge, just by filling the electrolyte and waiting about 20 minutes. Then the battery can be replaced and used for starting the vehicle. In case the additional charging is recommended for long life, the charging time is about 2-5 hrs.
• Initially fill the batteries with cool battery grade dilute sulphuric acid of 1.220 specific gravity. Allow the plates of the battery soaked with acid for about 20 minutes after filling acid.
• Allow cooling for 8-12 hrs.
• Commence initial charging at prescribed rates
• Working specific gravity of all batteries .1.240-+0.01
• Continue charging for 55 to 60 hrs till individual cells attain a proper charge voltage of 2.6 to 2.7 volts. For a 12v battery the top of charge voltage will be 15.6 to 16.2 volts. After this switch off charge.
• Top up all cells with 1.240 specific gravity battery grade sulphuric acid through proper level. Remove used battery from the vehicle and stack battery on vehicle carefully without reversed polarity (positive and negative). Remove the negative terminal first which is connected to the vehicle to avoid the danger of short-circuit when remo ving the battery from the vehicle. Never take off the aluminium foil or sealing tape until filling electrolyte.

• Wear protective glasses, gloves and clothing when handling with sulphuric acid. In case of accidental contact, flush externally with water and drink large quantities of water or milk. Get prompt medical attention.
• Batteries produce explosive gases: keep sparks and cigarette flames away
• Do not connect a battery immediately after bench charging, provide few hours rest before fitment in vehicle or equipment.
• Keep vent plugs tightly fitted and vent holes clean to allow free exit of gases.
• Keep out of the reach of children or untrained personnel.
