Datasheet of rechargeable batteries


Our advantages of rechargeable batteries


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-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.

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 .
