Henry! You should know better than this! "Pocket plate" NiCd's use a solution of potassium hydroxide (KOH) plus a little lithium hydroxide (LiOH) "slopping around in them". They are _definitely_ "wet" cells. Only "lead-acid" "wet" cell batteries have sulfuric acid "slopping around in them". There are some other wet cell technologies, but lead-acid and NiCd are the most popular. (NiCd has some significant advantages over lead-acid, like 20 year life expectancy as opposed to 5 to 7 for lead acid, plus much lower maintenance than even the so-called "maintenance free" lead-acids.) Clark ...and I thought Henry knew everything... :-) Disclaimer: The opinions expressed above are mine and not those of Schlumberger because they are NOT covered by the patent agreement!
