Solight DN25 – Smart AA/AAA NiMH Battery Charger, 4 Independent Slots, LCD Display

Solight DN25 – Smart AA/AAA NiMH Battery Charger with LCD Display and 4 Independent Slots

Individual battery charging, intelligent microprocessor control and a clear backlit display. The Solight DN25 is a practical wall charger designed for rechargeable AA and AAA NiMH batteries, providing convenient operation and automatic charge management.

Whether you use rechargeable batteries in flashlights, headlamps, remote controls or everyday household electronics, a reliable charger is an essential accessory.

The Solight DN25 combines easy operation with advanced charging management, allowing up to four rechargeable cells to be charged independently.

Four Independent Charging Channels

Unlike basic chargers that require batteries to be charged in pairs, the Solight DN25 offers four independent charging channels.

Each inserted battery is monitored and charged according to its individual condition.

This provides several practical benefits:

• Charge a single battery without needing a matching pair.

• Independent charging management for each cell.

• Support for compatible AA and AAA NiMH batteries.

• Individual charge completion based on battery condition.

• Convenient charging of cells with different remaining charge levels.

This flexibility is particularly useful when maintaining batteries for several different electronic devices.

Intelligent Microprocessor Control

The charger uses a built-in microprocessor to monitor and manage the charging process.

It incorporates Peak Voltage Detection (PVD) and minus Delta-U (-ΔU) detection technology.

These methods monitor changes in battery voltage to help determine when a rechargeable NiMH cell has reached full charge.

Once charging is complete, the charger automatically switches to a maintenance charging mode.

This reduces the need for manual supervision of the charging process.

Backlit LCD Display

The Solight DN25 features a backlit LCD display with graphical charging progress indication.

This provides clear visual information about the charging process.

The backlight makes the display easy to read in different lighting conditions.

Defective and Non-Rechargeable Battery Detection

An important safety feature is the charger's ability to detect:

• Damaged rechargeable batteries.

• Non-rechargeable cells.

• Incorrectly inserted batteries.

The charging system identifies unsuitable batteries and helps prevent unsafe charging attempts.

The Solight DN25 is designed for rechargeable NiMH batteries only. Do not use it to charge disposable alkaline batteries, Li-Ion cells or LiPo batteries.

Automatic Maintenance Mode and Safety Timer

After normal charge completion, the DN25 automatically switches to a maintenance charging mode.

An integrated 6.5-hour safety timer provides an additional safeguard by terminating charging after the specified period.

The charger is also designed to minimise heat generation during operation.

Charging Current – Up to 450 mA

The charging current depends on the battery size:

• AA batteries: maximum 450 mA

• AAA batteries: maximum 200 mA

For a 2000 mAh AA rechargeable battery, the manufacturer specifies an approximate charging time of 4.5 hours.

Actual charging time depends on battery capacity, remaining charge, condition and operating conditions.

Ideal for Household and Outdoor Electronics

The Solight DN25 is suitable for rechargeable batteries used in a variety of devices.

Typical applications include:

• LED flashlights and headlamps using compatible NiMH batteries.

• Remote controls and household electronics.

• Wireless keyboards and computer mice.

• Children's toys.

• Portable radios.

• Outdoor and travel accessories.

Independent charging channels make the charger particularly convenient for maintaining batteries used across several different devices.

Direct Wall Socket Operation

The charger plugs directly into a mains electrical outlet.

It supports a universal 100–240 V AC input at 50/60 Hz, making it suitable for different mains voltage systems.

A physical plug adapter may be required when travelling to countries using different socket types.
