FG150-12 best maintenance free lead acid 12v 150ah battery

VRLA Battery 12V 150AH | Dimension: 484x171x241x241mm

SKU: FG150-12 Category:

GRANKIA FG150-12 best maintenance free lead acid 12v 150ah battery is specifically designed for cyclic use over sustained periods of time.

The electrolyte (acid) in AGM batteries is fully absorbed in a sponge-like absorbent glass-mat between plates to prevent spillage, leakage and corrosion. The highly-porous nature of AGM separators allows for improved current flow between the plates when discharging and recharging.

The lead acid 12v 150ah battery is a low-cost, highly reliable and efficient, and popular storage choice for power quality, uninterrupted power supplies (UPS), and some spinning reserve applications.

12V 150AH 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.) VRLA technology

VRLA stands for Valve Regulated Lead Acid, which means that the batteries are sealed. Gas will escape through the safety valves only in case of failure.

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.

Lead Acid 12V 150AH Battery FAQ

  1. What does Ah stand for on a battery?

    Ampere hours — is the amount of energy charge in a battery that enables 1 ampere of current to flow for one hour.

  2. How many Ah battery do I need for home?

    As battery voltage is generally taken at 12 Volts, here is how you calculate the battery capacity. So, a battery with capacity equal to or higher than 150 Ah will suffice for your home.

  3. How long will a 12v battery last on an inverter?

    Most automobile and marine batteries will provide an ample power supply for 30 to 60 minutes even when the engine is off.
