> 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
Some Sealed Lead Acid batteries .say nickel –cadmium batteries will become conditioned to provide less power offer repetitious short
usage /discharge.
3. 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.
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 .
