GRANKIA manufactures long life sealed lead acid battery in CHINA.

FG80-12 smf 12 volt 80ah agm battery

 GRANKIA FG80-12 smf vrla 12 volt 80ah agm battery for garage door opener is constructed with Absorbed Glass Mat technology allowing for a low-maintenance and spill proof battery.

Flame Retardant ABS case and cover to UL 94 V-O for superior performance. Proven VRLA Absorbent Glass Mat (AGM) Technology that guarantees safe operation without maintenance and “non-restricted article” status for transportation.

Valve regulated sealed lead acid 12v 80ah agm battery charges up to two times faster than conventional alternatives. No need for checking Electrolyte level and topping throughout its life. Sealed construction Ensures no leakage of Electrolyte from Terminal or casing.

12V 80AH AGM Battery Features

1.) AGM technology

AGM stands for Absorbent Glass Mat. In these batteries the electrolyte is absorbed into a glass-fibre mat between the plates by capillary action.

2.) Low self-discharge

Storing batteries at lower temperatures thus reduces the rate of self-discharge and preserves the initial energy stored in the battery.

3.) Low internal resistance

Accepts very high charge and discharge rates.

4.) Puncture Resistant Case

Each of the 6 cells within this SLA battery is wrapped in a puncture resistant polyethylene envelope, so even if the outercase is pierced no leakage will occur.

5.) Maintenance-Free Design

Minimises technician time spent at site and on battery related callouts.

6.) Anti Buckle Separators

Internal plate buckling can kill a battery outright or simply reduce its lifespan. Our AGM separators gives the plates extra support to eliminate buckling.
