## Analysis of the LC-R064R2P Battery The **LC-R064R2P** is a specific model of Valve Regulated Lead Acid (VRLA) battery, manufactured primarily by Panasonic. It is part of the "LC-R" series, designed for high cyclic use and standby applications. ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Chemistry** | Lead Acid (VRLA / AGM) | | **Nominal Voltage** | 6 Volts | | **Nominal Capacity** | 4.2 Ah (Ampere-hours) | | **Terminals** | Faston 187 (4.75mm wide plug) | | **Weight** | Approx. 720g | | **Dimensions (L x W x H)** | 70mm x 48mm x 102mm | --- ### 2. Electronic Composition and Operation The internal "electronic" functionality of this part relies on electrochemical reactions rather than solid-state circuitry. * **Absorbent Glass Mat (AGM) Technology:** Between the lead plates, there is a fiberglass mat soaked in sulfuric acid electrolyte. This allows for a "dry" construction where the battery is spill-proof and can be mounted in various orientations. * **Valve Regulated Design:** It features a one-way pressure relief valve. If pressure builds up during overcharging, the valve releases gas to prevent the casing from bursting. * **Recombination Principle:** During normal charging, oxygen generated at the positive plate migrates to the negative plate to recombine into water, minimizing fluid loss. --- ### 3. Usage and Application Because of its 6V output and 4.2Ah capacity, it is commonly found in small-to-medium electronic devices requiring a steady DC power source: 1. **Emergency Lighting:** Provides backup power when the mains fail. 2. **Medical Equipment:** Used in portable monitors or infusion pumps. 3. **Uninterruptible Power Supplies (UPS):** Smaller units for networking gear. 4. **Security Systems:** Backup power for alarm panels. --- ### 4. Charging Guidelines To ensure the longevity of the LC-R064R2P, specific voltage parameters must be followed: ```text Cycle Use (Charging): 7.25V to 7.45V Standby Use (Float): 6.8V to 6.9V Initial Current: Less than 1.68 Amperes ``` ---
