FG120-12 maintenance free 120ah deep cycle battery 12v
VRLA Battery 12V 120AH | Dimension: 331x174x214x219mm
GRANKIA FG120-12 maintenance free 120ah deep cycle battery 12v is designed to be deeply discharged and recharged hundreds of times.
GRANKIA AGMs use more lead, heavier plates with high-density paste and other proprietary materials. It can enable them to deliver more reserve power and maintained capacity over many life cycles.
Due to its outstanding performance, the maintenance free 120ah deep cycle battery is a favorite in a wide variety of applications. Maintenance-free and leak-proof, the battery is ideal for standby projects that require minimal monitoring.

120AH Deep Cycle 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 overcharging or cell 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.

Deep Cycle Battery FAQ
-
What does deep cycle mean in batteries?
A deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged.
-
How long should a deep cycle battery last?
Most deep cycle batteries can last up to six years with proper care and charging. It’s up to you that your battery isn’t being damaged by your charging routine.
-
Are deep cycle batteries worth it?
For the uninitiated, a deep cycle battery is essential for providing power over a sustained period of time.
