Just purchased a slimline eagle spectrum...Its absolutely like new(circa 1993)alkaline battery was never used and Nicad was probably used once and sat in a closet ever since...Is there any way to bring back the nicad to charge as apparently hasn't been charged since or do I have to buy a replacement..I know Jimmy Sierra had a device years ago but feel the battery just died from age..By the way the customs programs were like they came out of the factory and the unit works great in every facet..Sort of like finding a needle in a haystack and does one feel standing in a closet since 93 has damaged the charger also. As it detector works perfectly hope it stays that way..Any ideas from the forum...
