Default Re: A reminder, a warning..

The amount of used test gear I've bought which 'works well' and has a gooey mess of a battery (usually a D cell) at least several years old inside must be legion. Fortunately often the battery compartment (eg in Avos) will limit the spread of goo/rot/corrosion and in the worst cases replacement terminals will give reliability I always try and scrape out any green muck on the plastic and use a damp cloth with bicarb on it for final wipe before drying. However VTVM with D cells housed in the middle of the electrics are always bad news - either the tracks go or the mounting bits are covered in white corrosion meaning rebuilds.
