It is a function of age primarily.   Environment can affect it somewhat.

George,

 

Is battery life a function of just age (how old the battery is) or does using the keypad more to locate DSOs shorten the life span?  I rarely use the keypad to locate targets, using my planetarium program instead.

Jack,

 

It never hurts to replace it every 4-5 years before the database dies.

George,

 

This is good to know.  My replacement battery arrives by the end of the week and I will be swapping it out next weekend.

Jeff,

 

You should be good for 20 to 30 seconds…no rush, but I wouldn’t go get a cup of coffee while changing the battery.   <G>

I just replaced a keypad battery (and a cord) (and I have another keypad which will also get a new battery as soon as I get some time). 

  

It seemed the DB did not get lost when I swapped the battery... tho i might not have checked the Messier objects.   

How long will the keypad memory persist without a battery?

Jeff,

 

George at AP told me if I place the new battery next to the original one and quickly swap them out, the databases will not be lost.  I do not know how quick I need to be.  I guess I will find out as the battery in the keypad has not died, but I want to change it before it does.  BTW the battery for my keypad was $25 plus shipping.

Just had this happen to me as well.  

 

The custom battery is a bit expensive but once in every 10 to 12 years ain't too bad.  Removal and installation of the battery requires care but is straightforward as it reloading the database, though it can take a while.

 

I also went to the .19 firmware version.  Jury is still out on that one.

It is possible that the keypad battery has died.  I understand when it does, the stars and planet databases still work, but catalogs like the Messier and NGC objects get corrupted.  I just ordered a battery for my keypad before it dies.  Once it does, then you have to replace the battery and then reload the DSO databases.

 

Yours truly,

Starting to reuse my Mach 1 mount after a few years and have found that although the stars and sol data base is ok. The messer database is corrupted - with things like Crab Nebula is in Ursa minor. Any one seen this behavior?
