Click to expand... 14 years is a good run. Rule of thumb says 10 years on a coin cell. When the time comes use a paint pen to write the last hour reading you remember on the panel near to the meter, and replace meter with a new one. A “permanent” Sharpie will fade. Paint pens are similar but harder to find.
