12V 7Ah rechargeable lead-acid battery Suitable rechargeable battery for use in buffer mode (stand-by use) in which a constant current supply is required. Made with AGM technology (absorbed glass matt - in which the lead plates are interspersed with glass fiber separators that absorb the electrolyte) which allows it to be used in all positions (except upside down). This feature, combined with the totally hermetic, maintenance-free construction makes them an economical but extremely reliable choice in various contexts: at home and in the office (backup systems for alarm systems, video surveillance, fire protection, home automation systems, automatic doors and gates, backup batteries for UPS) in industry (process continuity, surveillance and video control) and in various electronics sectors (power supply for PLC, Arduino, Raspberry, etc.). The 12V / 7Ah format is by far the most used in various sectors of electronics, home automation, entertainment, both home, in many models of ups and in some toy machines.  Produced with high quality materials to ensure excellent performance to connected equipment. This battery is suitable for general applications such as alarm and security systems, communication and control systems, emergency systems, toys and power tools. The battery capacity is determined considering the discharge at 1 / 20° of the nominal capacity in 20h with 10.5 V end of discharge. We recommend using a suitable and appropriate recharging device.   Specifications Nominal voltage: 12V Nominal capacity 20Hr: 7Ah  Nominal voltage 12 V Buffer charge voltage 13.8 V / Cyclic 14.5 V at 20° C Voltage 12V Capacity 7Ah
