Stagnant acid: All of the electrolyte is sorbed in the exceeding thin fiberglass, clapboard and anode. So rechargeable Lead-Acid battery can be placed and used discretionarily.

Safety, seal: The unique structure and seal technique ensure no electrolyte overflow from the port or the cover.

SMF: Do not check the electrolyte proportion or add water during the anticipative life.

No corrosive gas produced: The gas which is produced during the charging is compounded by the oxygen. So no corrosive gas is produced during the normal use.

Safe gas release valve: Our lead-acid battery uses low pressure safe Valve. The valve will open automatically when the pressure is too large after the false use, and then close automatically.

Long lifespan: The immune and the structure of the alloy ensure the long lifespan of the battery (6V - 12V, 3 - 5 years), (2V large battery: 10 years) the cycle life is between 25~1000 according to the degree of the discharge.

Low self-discharge: Lead-acid is low self-discharge depend on the high purity materials. The losing part of the battery is 3% per month under the 25 degree. Low
Temperature can reduce the losing.

Good instauration function: The advanced electrode and electrolyte materials improve the instauration function.

Strong reliability: The capacity of the lead-acid is jarless after the over Charging, over discharging and jounce. The voltage, capacity and seal will be tested carefully before the delivery.

High capacity: Small cubage, high energy are the characteristic of lead-acid batteries. What's more, many of them are designed for the high energy output.
