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.
