The batteries can be recycled when they can no longer be recharged; to find a recycling location near you, simply copy this link to your browser: call2recycle.org/locator/
Supplied in certified frustration free packaging; recyclable
Same product, new look. The appearance of the batteries you receive may vary.
Pre-charged and ready to use, can be recharged 1000 times with minimal power loss
Note on Ni-MH batteries: Please check the compatibility of the device with 1.2V NiMH batteries. The operating time may be shorter than 1.5V alkaline batteries. Please check the correct fit as Ni-MH batteries are slightly larger than alkaline batteries according to IEC standards. Replace all batteries at the same time and refer to the specific requirements in the instruction manual of the device.
NOTE: To avoid damage or unwanted rapid discharge of batteries, do not mix: non-rechargeable batteries with rechargeable batteries; fully charged with partially or low charged batteries; new with old batteries; batteries with different mAh capacities; different brands.
Long battery life; the extremely slow gradual self-discharge keeps the capacity at 80% for 24 months
CHARGER TIPS Only use Ni-MH specific chargers with independent charging channels and voltage monitoring to avoid overcharging or undercharging. Avoid chargers that only have a timer and never use chargers intended for other battery types (such as NiZn or Li-ion) as this may cause damage or leakage.
AAA battery (4 pack, 800 mAh); ideal for digital cameras, remote controls, toys and more
