The **Panasonic LC-R0612P** is a high-performance, valve-regulated lead-acid (VRLA) battery. It is specifically designed for standby applications, emergency lighting, and uninterruptible power supplies (UPS). --- ## 1. Technical Specifications The core electrical characteristics are summarized in the table below: | Feature | Specification | | :--- | :--- | | **Nominal Voltage** | 6V | | **Nominal Capacity** | 12Ah (20-hour rate) | | **Chemistry** | Lead-Acid (AGM - Absorbent Glass Mat) | | **Dimensions** | 151mm (L) x 50mm (W) x 94mm (H) | | **Weight** | Approx. 1.85 kg (4.08 lbs) | | **Terminal Type** | Faston 187 (4.75mm) or Faston 250 (6.35mm) | --- ## 2. Key Electronic Features The LC-R0612P incorporates several design elements that distinguish it from standard automotive batteries: ### A. AGM Technology It uses **Absorbent Glass Mat (AGM)** separators. This means the electrolyte is absorbed into fiberglass mats between the plates, making the battery: * **Leak-proof:** It can be operated in various orientations (except continuous inverted). * **Maintenance-free:** No need to add water throughout its service life. ### B. Discharge Characteristics The internal resistance is low, allowing for a high discharge rate. This is critical for equipment that requires a sudden surge of power. ### C. Charging Parameters To ensure longevity, the charging voltage must be strictly regulated: * **Cycle Use:** 7.25V to 7.45V (at 25°C) * **Standby (Float) Use:** 6.8V to 6.9V (at 25°C) * **Maximum Charging Current:** 4.8A --- ## 3. Common Applications Due to its reliability and 6V output, it is commonly found in: * **Medical Equipment:** Portable monitors and diagnostic tools. * **Security Systems:** Backup power for alarm panels. * **Emergency Lighting:** Powering exit signs during outages. * **Test Instruments:** Field-ready electronic measurement devices. --- ## 4. Safety and Maintenance * **Venting:** Features a one-way pressure relief valve to prevent gas buildup. * **Storage:** Should be recharged every 6 months if stored at 25°C to prevent "sulfation." * **Housing:** Typically made of UL94 HB or UL94 V-0 flame-retardant ABS resin.
