Interesting. I've never heard of "non-magnetic" batteries or, for that
matter, "magnetic batteries". Be interested to hear if you find any.


Inside the Richie cover, they listed 1 EverReady part number and 1 RaOvac
number.

I had never considered the possibility of any battery, other than the old
zinc cased batteries, being non magnetic. I will restate, that the old
batteries I found in this compass did have a dramatic effect on the bearing
I was taking.. Once removed, the bearings coincided with other known
bearings. BTW. The bearing I was trying to take was 004 magnetic while the
compass, with the old batteries, was reading around 315 magnetic. That's a
lot of deviation.

I'm not on the boat right now but will try to remember to write the numbers
down and do a Google search for them..

Since, personally, seldom use the hand bearing compass, I doubt that it will
be worth the effort or money to purchase replacements that will set in the
locker for years between uses.

Take out the bad batteries. Take compass to store and hold it near
batteries and see if it deflects. Its the steel case around the
battery, not the battery itself that is the problem and some batteries
do not have that steel case.

Good point. I had not thought about the case.
