A: Ni-CD stands for nickel-cadmium, Ni-MH stands for nickel-metal hydride. Nickel-metal hydride batteries have no cadmium added. Cadmium is hazardous to the environment.
A: Nickel-cadmium batteries must be recycled. Call 1-800-8-BATTERY or visit www.rbrc.com to find the recycling centers or participating national retailers.
There are currently no restrictions on the disposal of nickel-metal hydride batteries.
The Rechargeable Battery Recycling Corporation (RBRC) recycles the following portable rechargeable battery chemistries:
- Nickel Cadmium (Ni-Cd)
- Nickel Metal Hydride (Ni-MH)
- Lithium-Ion (Li-ion)
- Small Sealed Lead (Pb)*
- *Weighing less than 2 lb./1 kg.
These batteries are commonly found in cordless power tools, cellular and cordless phones, laptop computers, camcorders, digital cameras, and remote control toys.
A: No. However, if using a nickel-cadmium charger to charge nickel-metal hydride batteries, charging should be monitored to avoid overcharging.
A: Memory effect on a battery is the loss of run-time per charge over the life of the battery. To avoid memory effect and attain maximum performance, discharge the battery completely during each use.
Nickel-metal hydride has no memory effect and can be charged or topped off at any time without affecting battery life.
A: Nickel-metal hydride (Ni-MH) batteries provide up to 200% more power than nickel-cadmium (Ni-CD) rechargeable batteries, which will significantly outperform alkaline batteries in most digital applications and will greatly outperform Ni-CD batteries in high-drain applications.
Ni-MH batteries have a rechargeable life of up to 1000 cycles, 25% more than Ni-CD.
Ni-MH batteries have no cadmium added. Cadmium is hazardous to the environment.
A: Very economical batteries that can be reused approximately 1,000 times. You can recharge them approximately 1,000 times and the per-unit cost is approximately 4 JPY. In addition, end-of-life Eneloop batteries can be recycled, and they are, thus, really environmentally friendly next-generation batteries.
