I have a Lumedyne 244 system & two heads which I purchased in 1988---over the years, I have used it less and less, but on occasion I pull it out of the mothballs.
My question re: the battery-------will a battery for this system "die" over time & need to be replaced, or does it need occasional re-charging over the years to keep it active. Yes, I couild run tests & determine the answer, but I welcome input from others as I question my procedures.
Thank you--Raymond
