This document describes the Panasonic Rechargeable Nickel-Cadmium Battery Charger, Model BQ-4C, providing operating instructions, safety guidelines, maintenance tips, and a limited warranty.
Function Description
The Panasonic Charger Model BQ-4C is designed to recharge Panasonic Rechargeable Nickel-Cadmium type batteries. Its primary function is to provide a safe and efficient way to replenish the power of these specific battery types, allowing for repeated use and reducing the need for disposable batteries. The charger is equipped to handle multiple battery sizes, making it a versatile tool for users with various rechargeable devices. It features LED pilot lamps that indicate when charging is in progress, ensuring users can easily monitor the charging status. The charger is designed for household use, plugging into a standard 110-120 volt AC outlet.
Usage Features
The charger offers several key usage features that enhance convenience and safety:
- Versatile Charging: The BQ-4C can charge all five sizes of Panasonic Rechargeable Nickel-Cadmium batteries: D, C, AA, AAA, and 9 Volt. This broad compatibility makes it a comprehensive charging solution for a range of electronic devices.
- Paired Charging for D, C, AA, AAA Batteries: For D, C, AA, and AAA batteries, the charger requires them to be loaded in identical pairs within charging compartment No.1 or No.2. A single battery of these sizes cannot be charged alone in these compartments. This ensures balanced charging and optimal performance.
- Single 9 Volt Battery Charging: Unlike the other battery types, a single 9 Volt battery can be charged independently in its dedicated compartment. Users must ensure proper mating of connectors and snap the battery into place.
- Polarity Protection: The charger incorporates polarity reverse protection. Users are instructed to ensure the positive terminals of the batteries are facing the directions shown by the diagram in each battery position to prevent improper loading, which could lead to permanent battery damage.
- Charging Indicator Lights: LED pilot lamps serve as charging indicators. These lights illuminate when charging is being conducted for each loaded compartment, providing visual confirmation that the batteries are actively charging. If a light does not come on, users are advised to check if batteries are properly inserted and making contact, and if the charger is plugged into a working AC outlet.
- Fast Charging Capability: The BQ-4C offers fast charging for D, C, AA, and AAA size batteries, fully charging them in approximately 6 hours. This is significantly faster than conventional charging units, which might take up to 16 hours for the same battery types. For 9 Volt size batteries, a full charge takes approximately 14-16 hours.
- Flexible Loading: The charger can accommodate two or four pieces of D, C, AA, or AAA batteries at one time, or one or two pieces of 9 Volt batteries. This flexibility allows users to charge multiple batteries simultaneously, catering to different needs.
- Continuous Charging: Batteries can be left in the charging unit even after the charging time is over without harm. However, for maximum battery life, it is recommended to remove batteries after they are fully charged or unplug the charger.
- Operating Temperature Range: The charger is designed to operate effectively within temperatures above 32°F (0°C) and below 104°F (40°C). The most efficient charging temperature range is between 50°F (10°C) and 86°F (30°C).
- Compact and Portable Design: The charger's design emphasizes compactness and portability, making it easy to store and transport.
- Safety Precautions: The manual provides crucial safety instructions, including warnings against charging non-Panasonic rechargeable Nickel-Cadmium batteries, exposing the charger to rain or snow, using unrecommended attachments, operating with a damaged cord or plug, and disassembling the unit. It also advises against placing anything on top of the charger during operation and keeping it out of children's reach.
Maintenance Features
Maintenance for the Panasonic Charger Model BQ-4C is minimal and straightforward, focusing on simple cleaning and proper handling to ensure longevity and safe operation:
- Simple Cleaning: To maintain the charger, users should unplug it from the AC outlet and wipe it with a damp cloth to remove any dirt and grime. After cleaning with a damp cloth, it should be wiped again with a dry cloth.
- Avoid Immersion: A critical maintenance instruction is never to immerse the charger in water or any other liquid. This prevents damage to the internal electronic components and ensures safe operation.
- Cord Care: To reduce the risk of damage to the electric plug and cord, users should pull by the plug rather than the cord when disconnecting the charger. Additionally, it's important to ensure the cord is located so that it will not be stepped on, tripped over, or subjected to damage or stress.
- No Extension Cords: The use of an extension cord is not recommended, as it may result in a risk of fire and electric shock.
- Professional Servicing: In case the charger has received a sharp blow, been dropped, or otherwise damaged, or if service or repair is required, users are instructed not to disassemble it but to take it to a qualified serviceman. Incorrect reassembly can lead to electric shock or fire.
- Unplug Before Maintenance: Before attempting any maintenance or cleaning, the charger should always be unplugged from the outlet to reduce the risk of electric shock.
These features collectively highlight the charger's user-friendliness, safety considerations, and ease of upkeep, contributing to a reliable and long-lasting product experience.
