>Main Features


1. Maintenance free sealed lead acid battery


As it is valve-regulated sealed lead acid battery.sealed and glass mat is used .acid is trapped inside. so refilling is not needed and is


leak proof.


2. No memory effect

The self –discharge rate for FOBERRIA Sealed Lead Acid Battery is about 2-3% per month at room .temperature compared with 20-30%


for other common battery systems.


4. Longer service life


Used thick and massive calcium grate ensure that FOBERRIA battery has a longer service life over 10years.


5. High discharge rate


Since the internal resistance is low .the battery can provide high rate of discharge.


6. Wide operation temperature range


VRLA Sealed Lead Acid Battery capacity is rated at 25°C, and will operate from 15°C +50°C when it is fly charged Ambient temperature


is 25°C.Service life will be more efficient under 15’C to 25”C .
