2. Safety Information

Observe the following safety precautions to prevent injury or damage to the product:

• Use this charger exclusively for NiMH rechargeable batteries. Do not attempt to charge alkaline, NiCd, or Li-ion batteries, as this may cause damage, leakage, or explosion.
• Ensure batteries are inserted with correct polarity (+/-) as indicated on the charger and batteries. Incorrect insertion can lead to damage.
• Do not disassemble, modify, or short-circuit the charger or batteries.
• Avoid exposing the charger or batteries to water, fire, extreme temperatures, or direct sunlight.
• Keep out of reach of children.
• If a battery shows signs of leakage, discoloration, deformation, or any other abnormality, discontinue use immediately.
• Always replace all batteries in a device simultaneously. Mixing old and new batteries, or different types of batteries, can reduce performance and potentially cause leakage.
• Consult your device's manual for specific battery requirements and compatibility with 1.2V NiMH batteries. Note that 1.2V NiMH batteries may have a shorter runtime than 1.5V alkaline batteries in some devices.
• NiMH batteries are slightly larger than alkaline batteries to meet IEC standards. Verify proper fit in your device.

3. Package Contents

The Amazon Basics NiMH Rechargeable Battery Kit includes:

• 1 x 4-Slot NiMH Battery Charger (European plug)
• 4 x AA 2000mAh NiMH Rechargeable Batteries

Note: This kit includes a charger with a European plug. No separate cable is required.

4. Setup

1. Unpack the Components: Carefully remove the charger and batteries from their packaging.
2. Inspect for Damage: Before first use, inspect the charger and batteries for any visible damage. Do not use if damaged.
3. Plug in the Charger: Insert the charger directly into a standard European wall outlet. Upon plugging in, all LED indicators will briefly light up and then turn off, indicating a quick startup diagnostic.
4. Insert Batteries: Insert NiMH AA or AAA rechargeable batteries into the charging slots. Ensure correct polarity by matching the '+' and '-' symbols on the battery with those on the charger. The charger can charge 1 to 4 batteries simultaneously, in any combination of AA and AAA.

7. Troubleshooting

If you encounter issues with your charger or batteries, refer to the following:

• Batteries not charging (Rapid Flashing LED):
  • Ensure the battery is a NiMH rechargeable type. The charger is not compatible with alkaline or other battery chemistries.
  • Check for correct battery polarity. Reinsert the battery, ensuring the '+' and '-' terminals align with the charger's markings.
  • The battery may be defective. Try charging a different NiMH battery to confirm charger functionality.
• Slow charging or reduced battery life:
  • Ensure the charger is plugged directly into a functional wall outlet.
  • Batteries have a limited number of charge cycles. If batteries are very old or have been recharged many times, their capacity may naturally decrease.
  • Ensure the batteries are fully discharged before recharging for optimal performance, though NiMH batteries do not suffer from a "memory effect" as severely as NiCd.
• Charger not powering on:
  • Verify the wall outlet is functional by plugging in another device.
  • Ensure the charger is securely plugged into the outlet.
