12v sealed battery

12v sealed battery

CA12-65-Y Product Feature Long-life design (25℃): 10 or 18 years Low self-discharge rate: ≤3%/Month Good high rate discharge performance High sealed reaction efficiency: ≥99% Wide operation temperature range: -20℃~60℃ Grid: thicker grid and radiative grid structure Structure: Compact design,...

Product Details

12v sealed battery have changed little since the 1880's although improvements in materials and manufacturing methods continue to bring improvements in energy density, life and reliability. All lead acid batteries consist of flat lead plates immersed in a pool of electrolyte. Regular water addition is required for most types of lead acid batteries although low-maintenance types come with excess electrolyte calculated to compensate for water loss during a normal lifetime.

Datasheet of 12v sealed battery


Product Feature of 12v sealed battery


Gelled electrolyte, no flow, no leakage or no gradation of sulfuric acid.

The positive plate is tubular plate, which can effectively prevent the active materials from falling off.

PVC-SiO2 separator, which is special for gel battery with tiny holes.

The separator has high volume porosity, low electrical resistance and excellent wettability

Maintenance-free during the whole service life. 

Low self discharge rate

Proof against deep discharge according to DIN 43539 T5

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 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.


Emergency Light
Security System
Power storage plant
