This 12V7Ah Battery for Alarm System is a valve-controlled lead-acid battery, which adopts high-quality absorbing glass mat (AGM) separator and high-purity raw materials to provide an efficient and powerful energy storage solution. Its electrolyte is completely absorbed in the AGM diaphragm, and the electrode plate has a larger size design, which makes it have better discharge performance. At the same time, the unique through-wall welding method of the battery can increase the current conduction ability and improve the anti-vibration performance of the battery, which can keep stable operation when used in various environments. This will help to ensure the safety of your alarm system and make your family or business feel at ease.

Features

The electrolyte of the 12V7Ah Battery for Alarm System adopts thin liquid design and is absorbed in AGM diaphragm, so there is no flowing electrolyte in the battery, and water is not needed during use, which greatly reduces the maintenance strength. The battery has a low self-discharge rate, which ensures that it can keep its charge during long-term storage and provide reliable power when needed. With excellent sealing technology, it can also prevent pollution and corrosion caused by external gas and or dust, so as to protect its internal components and promote long-term and reliable service life.
