Loss of capacity for Ni/H2 cells on storage has been a problem for spacecraft applications. A relief from this problem is demonstrated by the use of nickel electrode precharge (deficit amount of hydrogen) rather than the customarily used hydrogen precharge (excess amount of hydrogen). The use of this precharge does not appear to have any short or long term harmful effects on the cell performance. Nickel electrode precharge not only is harmless but also may be beneficial by relieving a long term pressure build-up which might be a problem for a long life application.
