VRLA Battery 12V 7AH | Dimension: 151x65x94x100mm
GRANKIA FG7-12 valve regulated lead acid ups 12v 7ah battery utilizes Absorbent Glass Mat Technology which is capable of delivering high currents on demand and offers a relatively long service life.
Lead acid batteries can be found in a wide variety of applications including small scale power storage such as UPS systems, inverter, starting lighting and ignition power sources for automobiles, along with large, grid-scale power systems.
The battery rating, 12V 7Ah, means that 7 amps can be drawn from the battery at 12 volts for an hour, this is its energy content.
A higher AH battery will last longer than a lower AH battery. That’s indisputable. The application of these batteries makes all the difference.
Yes you can. A 12v charger can charge any 12v battery.
