Maintenance Free Sealed Lead Acid Battery 12V 120a

Maintenance Free 12V 120ah Sealed Lead Acid Battery Rechargeable For Solar System



> 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. Low self discharge



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.



3. Longer service life



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



4. High discharge rate



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