Its unique features enable it to be used in applications and environments untenable for other widely available battery systems. It is not surprising, therefore, that the nickel-cadmium battery has become an obvious first choice for users looking for a reliable, long life, low maintenance...

By providing a large spacing between the positive and negative plates and a generous quantity of electrolyte between plates, good electrolyte circulation and gas dissipation are provided, and there is no stratification of the electrolyte as...

Low temperature operation has the effect of reducing the performance, but the higher temperature characteristics are similar to those at...
