Battery AGM 12V 18Ah maintenance-free for UPS ALARM
What is the AGM battery? The AGM is an energy storage battery with a wide range of commercial applications. Not only can we power toys and alarm systems with it, but it also forms the heart of any UPS. Green Cell AGM batteries have a very wide range of applications. They can be used for both cyclical and buffer operation.
Cyclical operation
The cyclic use of a battery is to use it as a stand-alone energy source. AGMs of this type are designed for very frequent charging and discharging. In this way, they are used in wheelchairs, photovoltaic installations, golf carts, toys and lawnmowers.
Buffer operation
Buffer operation allows the battery to act as an emergency power supply for the connected device. A battery connected to a power system provides additional power in the event of a main power source failure. They are used in this way in alarm systems, UPSs, cash registers or emergency lighting.
Maintenance-free operation
Batteries made using AGM technology are designed to provide the greatest possible safety during use. Thanks to the self-regulation function (VRLA valves), AGMs provide up to 5+ years of maintenance-free operation. This increases operational safety, regardless of the position of the battery.
Safety
AGM batteries are designed to withstand even the most extreme conditions. The fibreglass used means that the electrolyte is sealed in the housing which allows the battery to be used in any position without fear of the contents spilling out. This is particularly important in the case of powered toys that are exposed to various types of shock. This makes Green Cell AGM batteries completely safe for users.
