## Long description

EATON battery CSB HR1234W F2, 12V, 9Ah, F2 backup lead-acid battery (12 V, capacity 9 Ah) in VRLA (AGM) design It is a design in which the internal pressure is regulated using valves (VRLA - Valve Regulated Lead Acid). This is the most widespread, most reliable and most cost-effective standard for industrial UPS and security systems. The advantages of this VRLA/AGM design are mainly the following: \* higher maximum discharge power - key to overcoming starting surges of connected electronics \* absolutely maintenance-free (in terms of refilling distilled water and checking electrolyte) \* longer battery cell life - optimal life of 3 to 5 years in standby mode \* high reliability - CSB cells show minimal differences in internal resistance, which is critical when connecting multiple cells in series in one UPS \* high resistance to shocks \* Leakproof – closed/unbreakable (AGM technology - the electrolyte is ''trapped'' in glass fabric, which prevents it from leaking and allows operation in any position) \* contact type, pole (connector): Faston 6.3 mm (F2) Specifications Product type: backup (stationary - operation at a fixed location) battery Battery capacity: 9 Ah (at 20-hour discharge) Rated voltage: 12 V Battery technology: VRLA / AGM (Absorbed Glass Mat), lead-acid Type of contact, pole: Faston 6.3 mm (F2) Max. discharge current: 130 A (within 5 seconds) Low self-discharge: less than 10% after 90 days, can be stored for up to 6 months at 25°C - battery must be fully charged before use Dimensions (WxHxD): 151 x 100 x 65 mm (height of battery with connectors) Weight: 2.5 kg Widely used: in UPS backup power supplies, high-load devices, in electronic fire systems (EPS), in electronic security systems (EZS), telecommunications.
