• Material    Grade A original lead , purity near 100%
• Production time   make lead plate ourself , delivery time about one week
• Price   We are big factory and prodce lead plate instead of purchasing,  so can control the cost ,quality and production time easily.
• Technology    advanced welding machine ,not easy shourt-circuit ,ensure batteries long life.
• Quality     All batteries should be tested 5 times before packing to ensure quality OK.
• Package    professional workers ; Non fumigation pallets can be exported to all countries .
• Low self-dischargeThe use of analytically pure sulphuric acid electrolyte and reasonable arrangement of special additives can effectively reduce the self-discharge speed of the batteries.
• High safetyThe 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.
• 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 .
