Ni-mh: The Long Life Battery!

By:




Mobility is the most important factor in modern lifestyle. Due to cell phones, portable computers and other electronic devices people now are much more effective than ever before. The need for mobility leads to a need for mobile power sources.

Gladly we can rely on new batteries being developed at a similar pace as electronics. Without being produced with heavy metals, Ni-NH cells provide far more power than the classic Ni-Cd battery. The exciting new technology used in the sealed Ni-MH rechargeable batteries provides optimum results for battery-powered devices, in terms of performance and environmental friendliness.
Being introduced in 1988 Ni-Mh batteries are still at an early stage of their development, but it is already clear, that they are well suited power sources for modern today's electronic devices.

One of the improvements of Ni-Mh batteries over Ni-Cd batteries is the 40% higher power density. The improved power density leads to longer run times and eventually to a longer battery life cycle. Also, they have a dramatically shorter charging time of an hour. They are very safe and robust and withstand the rough conditions "consumer devices" are often exposed to. In contrast to Ni-Cd and other cells, they are environmental friendly, as they do not contain lead, cadmium or mercury.

Today, the Ni-MH battery is hugely popular with high-end portable electronic devices where the performance of the battery translates into run-time, which is a major consideration for a consumer and influences their decision in the purchase of product. The weight reduction and reduced size are also important factors.

The technology used in Ni-MH and Ni-Cd batteries is very similar. They only differ by using hydrogen-absorbing negative electrodes in Ni-MH batteries and cadmium-based electrodes in Ni-Cd batteries. This leads to a much higher electrical capacity and no more toxicity. With the elimination of cadmium, the "memory" effect does not apply to Ni-MH cells.

When overcharged, exposed to high temperatures or other abuse, these safety vent in these batteries prevents the pressure from building up and therefore ensures safety. The only limit is that they have to be kept dry and clean in use and in storage. Even in storage it does not matter whether they are charged or discharged.

About the Author:
I have been working with battery driven vehicles and devices for ages. The short life of expensive batteries has always frustrated me, that's why I now recondition batteries for my own use to save money or to even make money by selling them.
