there is a fix out to prevent
the battery from prematurely draining in about a year as compared to 7
years that Micrologic advertised.


Ok, first a little reality check/physics lesson....

How long a battery will retain a charge is not based on the marketing
department of any manufacturer. They are all a bunch of liars, by trade.

From its age, I assume you are talking about the internal Lithium memory
backup battery in these old units. These batteries were made for 10 year
lifespans as the old memory chips drew a little leakage current....not
much, but it's there. If it drains in a year, the memory is leaking OR
there is leakage paths across the circuit board caused by WATER
INTRUSION, which is probably more close to the problem. ANY tiny wet
trail across that circuit board will kill the memory battery in short
order.

Memory batteries are usually soldered in. Searching for your ML250
simply results in seeing a thousand other owners begging for a manual and
information. If you can find any kind of number on the battery, go to:
http://www.batteriesplus.com/
and click up the live chat with the batteries plus tech support. If
anyone has them, they will, or can get them if they are still produced.

Personally, my advice is to DUMP IT! A great little handheld GPS with a
LOT FASTER PROCESSOR and LOT BETTER RECEIVER is less than $250. Those
old Micrologics only had like 6 channels, poor resolution and awful
reception. It's time to JUST JUNK IT!
