Low self-discharge

The use of analytically pure sulphuric acid electrolyte and reasonable arrangement of special additives can effectively 
reduce the self-discharge speed of the batteries.
High safety
The efficient safety valve made of imported rubber is durable, ageing resistant and corrosion resistant that can effectively
ensure the safety of internal pressure of the products in use.
Strong temperature adaptability 
It can be safety used between -30 ℃ and 50 ℃.
Safe and easy for use and transportation
They are manufactured with full load of charges containing no dissociated electrolytes. There is no need of using packages
for dangerous goods. And the land and water transportation meet the standards of international shipment.
Economical and practical 
The extremely high performance, long service life and low maintenance combined to make Tree batteries as

Maintenance free

As it is value-regulated .sealed and glass mat is utilized .acid GEL is trapped inside . so refilling is not needed and is leak proof.

Longer service life

Utilized thick and massive calcium grate ensure that TREE battery has a longer service life over 15years .
