Product Details

Sealed Lead Acid battery is such battery where electrical energy can be stored as chemical energy and this chemical energy is then converted to electrical energy as when required. The conversion of electrical energy into chemical energy by applying external electrical source is known as charging of battery. Whereas conversion of chemical energy into electrical energy for supplying the external load is known as discharging of secondary battery.

During charging of battery, current is passed through it which causes some chemical changes inside the battery. This chemical changes absorb energy during their formation.

When the battery is connected to the external load, the chemical changes take place in reverse direction, during which the absorbed energy is released as electrical energy and supplied to the load.


Product Features


• Excellent safety performance: No electrolyte leakage, battery swelling and cracking under normal use.
• Good discharging performance: With smooth discharging voltage and mild discharging platform.
• Good shock-proof performance: The fully charged and completely fixed battery, with 4mm amplitude and 16.7HZ frequency does have a normal open circuit voltage without leakage, batteries swelling or cracking problem after one-hour vibration.
• Good impact-proof performance: The fully charged battery is proved to maintain normal open circuit voltage and be without leakage or batteries swelling or cracking after dropping three times from 20cm height naturally to a 1 cm-thick hardwood board.
• Good resistance to over discharge: In temperature of 25 degree Celsius, the fully charged battery discharges with fixed resistance which is equivalent to the one required by 1CA discharge of the battery for three weeks, and it can restore capacity over 75%.
• Good resistance too high current: The fully charged battery is proved to be without conductive part melted or any apperance deformation after discharging at 2CA for 5 minutes or 10 CA for 5 seconds.
