Battery Charger GP B441 USB with 2×AA 2100 mAh and 2×AAA 800 mAh Rechargeable Batteries

GP B441 USB with 2×AA 2100 mAh and 2×AAA 800 mAh rechargeable batteries is a compact USB-powered charging kit designed for everyday household devices. The package includes a charger compatible with USB power sources and four NiMH rechargeable cells — two AA cells with 2100 mAh capacity and two AAA cells with 800 mAh capacity — intended to replace single‑use alkaline batteries in remotes, toys, flashlights and wireless peripherals.

Advantages

The charger uses a USB input for versatile power options from wall adapters, power banks or computer USB ports, allowing recharging at home or on the go. Included high-capacity AA batteries and standard-capacity AAA batteries provide a balance between runtime and compact size for different device requirements. Using NiMH rechargeable cells reduces the need for disposable batteries and lowers long-term operating cost while maintaining stable voltage for most consumer electronics.

Suitable for

• TV and media remotes
• Children’s toys and handheld gaming devices
• Portable LED flashlights and headlamps
• Wireless mice, keyboards and other peripherals
• Battery-powered household gadgets (clocks, thermometers, small radios)

Key specifications

• Charger input: USB power source (standard USB cable required)
• Cell chemistry: NiMH (rechargeable nickel-metal hydride)
• Included cells: 2 × AA, 2100 mAh each; 2 × AAA, 800 mAh each
• Charge configuration: accepts AA and AAA sizes (charger accommodates both sizes)
• Intended use: low- to medium-drain consumer electronics
• Form factor: compact, portable charging unit

How to use

Insert the AA or AAA rechargeable batteries into the charger following the polarity markings. Connect the charger to a USB power source using a compatible cable; charging begins automatically according to the charger’s internal circuitry. Charge times depend on the power source and battery state; monitor the charger’s indicator (if present) and remove cells once charging is complete. Allow batteries to cool briefly after charging before installing them into devices.

Usage recommendations

For best results, use GP NiMH cells for devices with frequent use and replace disposable batteries where possible. Avoid exposing batteries to extreme temperatures, and store charged cells in a cool, dry place. If a device will be unused for an extended period, remove the batteries to prevent gradual self-discharge or leakage.
