FAQs
Are these batteries truly ready to use out of the pack?
Yes, Duracell Pre-Charged rechargeable batteries are designed to be ready to use immediately upon purchase, retaining a significant charge for up to 5 years thanks to DURALOCK technology.
What type of charger do I need for these batteries?
You must use a charger specifically designed for Nickel-Metal Hydride (NiMH) rechargeable batteries. Using an alkaline or NiCd charger can damage the batteries.
How many times can these batteries be recharged?
These batteries can be recharged thousands of times, offering a long-lasting and economical power solution.
Can I use these in any device that takes AA batteries?
They are compatible with most devices that accept AA batteries. However, if a device requires exactly 1.5V and is very sensitive to voltage differences, they might not perform optimally, but this is rare for typical AA devices.
What does 'low self-discharge' mean?
It means the batteries lose very little of their stored charge over time when not in use. Duracell's DURALOCK technology allows them to retain up to 95% of their charge for up to 5 years.
Are these batteries environmentally friendly?
Yes, as they are rechargeable and can be used thousands of times, they significantly reduce the waste generated by single-use batteries.
What is the difference between mAh and V?
mAh (milliampere-hour) indicates the battery's capacity – how much energy it can store and deliver over time. V (Volts) indicates the electrical potential or 'push' of the battery. These batteries have a 1.2V nominal voltage and a 2400 mAh capacity.
Troubleshooting
Battery not recognized by device
Ensure the battery is inserted correctly with the correct polarity (+/-). Clean the battery and device contacts. Try a different set of charged batteries to rule out a device issue.
Device powers on but shuts off quickly
The batteries may not be fully charged, or the device may have a very high power demand. Ensure batteries are fully charged using a compatible NiMH charger. If the issue persists, try a different set of batteries.
Batteries do not seem to be charging
Verify that you are using a charger specifically designed for NiMH AA batteries. Ensure the batteries are properly seated in the charger. Check the charger's power connection and indicator lights. Consult your charger's manual.
Reduced battery life after several uses
Rechargeable batteries can degrade over time. Ensure you are fully recharging them after use and not over-discharging. Complete a few charge/discharge cycles, as this can sometimes restore capacity. If they are old, consider replacing them.
Pros and Cons
Pros
- Excellent for high-drain devices like digital cameras.
- Low self-discharge rate means they hold their charge for a long time.
- Environmentally friendly and cost-effective due to reusability.
- Convenient pre-charged state allows immediate use.
- Durable DURALOCK technology ensures long-term power retention.
Cons
- Requires a dedicated NiMH battery charger.
- Initial purchase price may be higher than disposable batteries.
- Slightly lower voltage (1.2V) compared to alkaline (1.5V) might affect some very sensitive devices, though generally not noticeable in most applications.
Setup, Compatibility & Care
Setup: These batteries are ready to use straight from the pack. Simply insert them into your device following the correct polarity (+/-).
Compatibility: The Duracell BUN0052A batteries are AA size and use Nickel-Metal Hydride (NiMH) technology with a standard 1.2V output. They are compatible with most devices that accept AA batteries, including digital cameras, flashlights, gaming controllers, toys, and portable electronics. Crucially, you must use a charger specifically designed for NiMH rechargeable batteries. Using an incompatible charger can damage the batteries or the charger.
Care: To maximize the lifespan of your rechargeable batteries:
- Always use a compatible NiMH charger.
- Avoid exposing batteries to extreme temperatures (hot or cold).
- Store batteries in a cool, dry place if not in use for extended periods.
- Do not attempt to disassemble or short-circuit the batteries.
- Clean battery contacts on both the battery and the device periodically with a dry cloth if they appear dirty.
