The **Panasonic LC-R061R3P** is a Valve Regulated Lead-Acid (VRLA) rechargeable battery. It is part of the "R series," designed primarily for main power applications and standby use. --- ### ## Technical Specifications Below are the key electrical and physical characteristics of the LC-R061R3P: | Parameter | Specification | | :--- | :--- | | **Nominal Voltage** | 6V | | **Nominal Capacity** | 1.3 Ah (at 20-hour rate) | | **Dimensions (L x W x H)** | 97mm x 24mm x 50mm | | **Total Height (with terminals)** | 55mm | | **Approximate Weight** | 0.30 kg (0.66 lbs) | | **Terminal Type** | Faston 187 (4.75mm wide plug) | | **Case Material** | Flame retardant ABS (UL94 HB standard) | --- ### ### Core Electronic Features 1. **Lead-Acid Chemistry (VRLA):** Unlike standard car batteries, this uses **AGM (Absorbent Glass Mat)** technology. The electrolyte is absorbed into a fiberglass mat between the plates, making it non-spillable and maintenance-free. 2. **Charge Characteristics:** * **Cycle Use:** 7.25V to 7.45V (at 25°C). * **Standby/Float Use:** 6.8V to 6.9V (at 25°C). * **Maximum Charging Current:** 0.52A. 3. **Low Self-Discharge:** These batteries are designed to retain their charge for long periods. Typically, they retain about 80% of their capacity even after 6 months of storage at room temperature. 4. **Oxygen Recombination:** The battery features a pressure-regulated safety valve. During charging, oxygen generated at the positive plate is absorbed by the negative plate, preventing water loss and the need for topping up. --- ### ### Common Applications * **Emergency Lighting:** Providing backup power when the mains fail. * **Security Systems:** Powering alarm panels and sensors. * **Medical Equipment:** Portable monitoring devices. * **Test Instruments:** Handheld electronic measurement tools. * **Toys and Hobbies:** Small RC vehicles or electric ride-ons. --- ### ### Safety and Maintenance * **Overcharging:** Avoid charging above 7.45V, as this can lead to "gassing" and reduce the battery's lifespan. * **Deep Discharge:** To ensure longevity, the battery should not be discharged below 5.25V (the cut-off voltage). * **Orientation:** While it can be used in various positions, it is generally recommended not to charge it in an upside-down position.
