## Overview of the LC-R064R5P The **LC-R064R5P** is a high-performance **Sealed Lead Acid (SLA)** battery manufactured by Panasonic. It is part of the "LC-R" series, which is specifically designed for high-cycle and standby applications. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Voltage** | 6 Volts | | **Nominal Capacity** | 4.5 Ah (20-hour rate) | | **Chemistry** | Lead Acid (VRLA - Valve Regulated) | | **Terminal Type** | Faston 187 (Standard 0.187" tabs) | | **Weight** | Approximately 0.72 kg (1.59 lbs) | | **Case Material** | Flame retardant ABS (UL94 V-0 or HB) | --- ### Key Internal Electronic & Structural Parts 1. **Lead-Calcium Grids:** Unlike traditional lead-acid batteries, this model uses a lead-calcium alloy. This reduces self-discharge and extends the shelf life of the battery. 2. **Absorbed Glass Mat (AGM) Separators:** The electrolyte is held in a glass-fiber mat between the plates. This makes the battery "spill-proof" and allows it to be mounted in various orientations (except inverted). 3. **Pressure Relief Valves:** As a **VRLA** battery, it features a safety valve system that releases gas if internal pressure builds up due to overcharging, preventing casing ruptures. 4. **Heavy Duty Plates:** The plates are designed thicker than standard starter batteries to handle deeper discharge cycles without warping or losing active material. --- ### Common Applications * **Emergency Lighting:** Provides reliable backup power during grid failures. * **Uninterruptible Power Supplies (UPS):** Used in smaller backup units for data protection. * **Medical Equipment:** Powers portable diagnostic tools and monitors. * **Security Systems:** Backup power for alarm panels and surveillance cameras. --- ### Charging Characteristics To maintain the lifespan of the LC-R064R5P, specific charging voltages should be used based on the application: * **Cycle Use:** 7.25V to 7.45V (at 25°C) * **Standby Use:** 6.8V to 6.9V (at 25°C) * **Initial Current:** Should be limited to **1.8A** or less.
