The compact and reliable BB Battery BC75-12/B5 battery (12V 75Ah) is a representative of the BC series with AGM technology, which provides high reliability and durability with minimal maintenance. Thanks to the sealed design without free acid, the battery can operate in any position except upside down. An ideal solution for backup power systems, security panels, telecommunications and medical equipment.
Key advantages of the BB Battery BC series battery
- Nominal capacity 75 Ah (C20) – stable operation even with prolonged consumption.
- Voltage 12V – standard for most backup and telecommunications systems.
- Maximum discharge current – up to 750A (5 seconds) for short-term peak load.
- Maximum charge current – 22.5A, which ensures safe and efficient charging.
- AGM (Absorbent Glass Mat) technology – high energy density and vibration resistance.
- Sealed case – the battery is maintenance-free and does not contain free acid.
- Ability to operate in a wide temperature range: from –20°C to +50°C.
- Low internal resistance – less than 25 mOhm for fast response to load.
