The **LC-R123R4P** is a high-quality Valve Regulated Lead-Acid (VRLA) battery manufactured by **Panasonic**. It is part of the LC-R series, designed specifically for standby power applications and cyclic use. --- ### ## Technical Specifications The following table highlights the primary electronic and physical characteristics of the LC-R123R4P: | Parameter | Specification | | :--- | :--- | | **Nominal Voltage** | 12V | | **Nominal Capacity** | 3.4 Ah (20-hour rate) | | **Chemistry** | Lead-Acid (AGM - Absorbent Glass Mat) | | **Terminal Type** | Faston 187 (4.75mm tabs) | | **Weight** | Approx. 1.20 kg (2.65 lbs) | | **Design Life** | 6 to 9 years (Eurobat standard) | | **Dimensions (L x W x H)** | 134 x 67 x 60 mm | --- ### ### Key Electronic Components & Construction The internal "parts" of this battery are engineered for durability and leak-proof operation: 1. **Absorbent Glass Mat (AGM) Technology:** The electrolyte is immobilized in a fiberglass mat between the plates. This allows the battery to be used in any orientation without leaking. 2. **Lead-Calcium Alloy Plates:** The grids are made of a lead-calcium alloy, which reduces self-discharge and minimizes water loss, making the unit "maintenance-free." 3. **One-Way Pressure Relief Valve:** If internal pressure builds up due to overcharging, this valve releases gas and reseals automatically to prevent the casing from bursting. 4. **ABS Resin Casing:** The outer shell is made of high-impact UL94 HB (or optional flame retardant V-0) plastic, protecting the internal cells from physical damage. --- ### ### Discharge Characteristics The performance of the LC-R123R4P varies based on the discharge rate: * **20-hour rate (170mA):** 3.4 Ah * **10-hour rate (310mA):** 3.1 Ah * **1-hour rate (2300mA):** 2.3 Ah ### ### Typical Applications * **Uninterruptible Power Supplies (UPS):** Providing backup for computers. * **Security Systems:** Powering alarm panels during grid failure. * **Emergency Lighting:** Ensuring visibility during power outages. * **Medical Equipment:** Portable monitors and diagnostic tools.
