Energizer CHFC3-EU Universal Battery Charger for NiMH AA, AAA, C, D, and 9V 6F22 Batteries

The Energizer CHFC3-EU Universal Battery Charger is a versatile and reliable solution for maintaining your rechargeable NiMH batteries. Designed to accommodate a wide range of common battery sizes, this charger provides an efficient way to keep your household devices powered. It features advanced microprocessor control to ensure safe and optimal charging cycles, protecting your batteries from overcharging and extending their overall lifespan.

Advantages

This charger offers significant flexibility by allowing you to charge two or four AA, AAA, C, or D batteries simultaneously, or one to two 9V 6F22 batteries. The integrated Delta-V control and timer mechanism automatically switch the device to a low-current maintenance mode once the batteries reach full capacity, ensuring they remain ready for use without risk of damage. The intuitive LED indicator system provides clear status updates, including active charging, completion, and error detection for worn or incorrectly inserted batteries.

Suitable for

• Charging AA and AAA NiMH batteries for remote controls and toys
• Powering C and D size batteries for flashlights and portable electronics
• Managing 9V 6F22 batteries for smoke detectors or professional audio equipment
• Households requiring a single charger for multiple battery formats

This charger is not suitable for charging non-rechargeable alkaline, lithium, or carbon-zinc batteries, as attempting to do so may cause leakage or fire hazards. It is also not designed for charging battery chemistries other than NiMH.

Key specifications

• Compatible battery types: NiMH
• Supported sizes: AA, AAA, C, D, and 9V 6F22
• Charging capacity: 2 or 4 units (AA, AAA, C, D) or 1 or 2 units (9V)
• Safety features: Delta-V control, timer, reverse polarity protection, and worn battery detection
• Power source: Wired power supply with included cable

To use the charger, connect the power cable to a standard wall outlet. Insert your NiMH batteries into the appropriate slots, ensuring correct polarity alignment as indicated by the markings. The LED indicator will glow steadily green to signal that the charging process has begun. Once the LED light turns off, the batteries are fully charged and ready for removal. If the LED flashes green, check that the batteries are properly seated or replace them if they are damaged.

What to consider before purchase

• Ensure your batteries are specifically NiMH type
