Do these batteries come pre-charged?
Rechargeable batteries typically come with a partial charge. For optimal performance, it is recommended to fully charge them before first use.
What type of charger do I need for these batteries?
You need a charger specifically designed for Nickel-Metal Hydride (NiMH) rechargeable batteries. Do not use chargers for other battery chemistries like NiCd or Alkaline.
How long do the batteries hold a charge when not in use?
These batteries can hold their charge for up to a year, making them suitable for devices that are not used regularly.
What is the capacity of these batteries?
These Duracell Rechargeable AAA batteries have a capacity of 750 mAh (milliampere-hours).
Are these batteries safe for all devices that use AAA batteries?
Yes, they are safe for any device that uses standard AAA batteries, provided the device is designed to operate with 1.2V rechargeable batteries. They are fully compatible with devices that use alkaline AAA batteries.
How do I know when the batteries are fully charged?
Consult your battery charger's manual. Most chargers have indicator lights that show when charging is complete, or they may automatically shut off.
Troubleshooting
Batteries do not charge
Ensure the charger is compatible with NiMH AAA batteries and is properly plugged in. Check that the battery contacts are clean and making good contact with the charger terminals. Try cleaning the contacts with an eraser.
Device does not power on or works intermittently
Verify the batteries are fully charged and inserted correctly with correct polarity (+/-). Ensure the device is clean and functioning properly. Try a different set of charged batteries.
Batteries drain very quickly
This can occur in very high-drain devices. Ensure batteries are fully charged. If the problem persists, the device might require higher capacity batteries or may have an internal issue. Consider if the batteries have reached the end of their charge cycles.
Batteries leak
Leaking is rare with rechargeable batteries but can happen if a battery is damaged or over-discharged. Remove leaking batteries immediately using gloves and clean the device contacts. Do not attempt to recharge leaking batteries.

Setup, Compatibility & Care
Setup:
- Initial Charge: It is recommended to fully charge the batteries before their first use. Insert them into a compatible NiMH AAA battery charger (sold separately) following the charger's instructions.
- Activation: Once charged, insert the batteries into your device, ensuring correct polarity (+/-).
Compatibility:
- These AAA batteries are compatible with any device that uses standard AAA alkaline batteries.
- Crucially, they require a charger specifically designed for Nickel-Metal Hydride (NiMH) rechargeable batteries. Do not use chargers for NiCd or other battery chemistries.
Care:
- Charging: Always use a suitable NiMH charger. Overcharging or using an incompatible charger can damage the batteries or the charger.
- Storage: Store batteries in a cool, dry place, ideally in a battery case. For long-term storage, ensure they are not fully depleted to preserve their lifespan. They retain their charge well for up to a year.
- Cleaning: If contacts appear dirty, gently clean them with a pencil eraser or a soft, dry cloth. Avoid using liquids or abrasive materials.
- Disposal: When batteries reach the end of their usable life, dispose of them responsibly according to local electronic waste regulations.
