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

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. > Specification Battery Model No. FBR12V120Ah Nominal Voltage 12V Capacity 20HR(5.25V) 120Ah (25ºC) 10HR(5.25V) 105Ah 1HR(4.80V) 74Ah Dimension Length 281±2mm Width 267±2mm Height 207±2mm Total height 210±2mm Approx.
