The **LC-R067R2P** is a specific model of a Valve Regulated Lead Acid (VRLA) battery manufactured by **Panasonic**. It is designed for high reliability and is commonly used in Uninterruptible Power Supplies (UPS), emergency lighting, and medical equipment. --- ### ## Technical Specifications Below is a breakdown of the electronic characteristics and physical dimensions of the LC-R067R2P. | Feature | Specification | | :--- | :--- | | **Nominal Voltage** | 6V | | **Nominal Capacity** | 7.2Ah (20-hour rate) | | **Chemistry** | Lead Acid (VRLA / AGM) | | **Terminal Type** | Faston 187 (4.75mm) or 250 (6.35mm) | | **Weight** | Approx. 1.20 kg (2.65 lbs) | | **Casing Material** | Standard UL94 HB (Optional Flame Retardant) | --- ### ## Internal Electronic Design The battery utilizes several key design components to manage electricity efficiently: 1. **Absorbent Glass Mat (AGM) Technology:** The electrolyte is absorbed into a glass fiber mat separator between the plates. This allows the battery to be spill-proof and used in various orientations. 2. **Oxygen Recombination:** During the charging process, oxygen generated at the positive plate is absorbed by the negative plate, preventing water loss and eliminating the need for maintenance. 3. **Pressure Relief Valves:** Equipped with one-way safety valves that release excess gas if internal pressure builds up (usually due to overcharging), protecting the structural integrity of the battery. 4. **Lead-Calcium Alloy Grids:** The plates use a lead-calcium alloy which reduces self-discharge rates and improves the lifespan compared to traditional lead-antimony plates. --- ### ## Charging Parameters To ensure the longevity of the LC-R067R2P, the following charging voltages must be observed: * **Cycle Use:** 7.25V to 7.45V (Initial current should be 2.88A or smaller) * **Standby (Float) Use:** 6.8V to 6.9V * **Temperature Compensation:** It is recommended to adjust voltage by -10mV/°C (Cycle) or -6mV/°C (Float) for variations from 25°C. --- ### ## Common Applications * **Backup Power:** Emergency lighting systems and fire alarms. * **Telecommunications:** Small-scale base station backup. * **Portable Devices:** Electronic test equipment and power tools. * **Medical:** Life-support backups and mobile medical carts.
