Rechargeable NiMH batteries are extremely earth-friendly products. You should really consider replacing most of your battery needs with NiMH batteries. Read on for quick facts about these rechargeable batteries.
NiMH (nickel-metal hydride) batteries are rechargeable and do not suffer from "memory effect" unlike NiCd (nickel-cadmium) batteries. To purchase rechargeable batteries online, you can hop over to this website.
NiCd batteries had to be completely discharged before recharging or the NiCd batteries would suffer a drop in voltage at the point the battery began recharging. NiCd batteries obviously contained cadmium, which is a dangerous toxic heavy metal. Cadmium can cause severe pollution to water, air and land if incinerated or buried by releasing toxic gas. Please recycle NiCd batteries!
NiMH batteries have charge capacities that differ depending on the battery type. For example, AA NiMH batteries can range from 1100 – 2800 mAh (mill ampere hour). AAA batteries can range from 850 – 1000 mAh. The higher the mAh, the longer the battery can go between charges.
The life of NiMH batteries can be extended by recharging the batteries often and not letting the batteries fully drain. NiMH batteries can typically be recharged between 500 – 1000 times depending on their use and how much each battery is drained before recharging.
NiMH rechargeable batteries are excellent for digital cameras, MP3 players, portable game systems, PDAs, portable CD players and toys because these are high-drain devices that will need to be recharged a lot.
