Re: [volt-nuts] Datron 1082
Just a side comment, if this battery is the same as the one made by the company Tenergy in Fremont, CA, they are just shy of 10 years old, so it looks like this Datron 1082 has had its battery changed once in recent memory.

Re: [volt-nuts] Datron 1082
I just took out the battery and it is a Tenergy 3.6 VDC 1200mAH ER14250 with tabs welded on.

I don't see any markings on the battery in my unit but I can't see the back side until I remove it. I assume the original was 3.6 VDC also but I'm not sure how to verify that. Thanks for the help.

I think the errors you are experiencing are because the memory battery is gone, so it won't matter now, this is for saving the cal data during future replacement to avoid these problems again.

Do you think it would make any difference if I paralleled the leads with a new one? I don't have a parts list to know what type the battery is so it's going to be a challenge to find a direct replacement. Wish I had a manual.

I would modify the battery with a coupe sets of leads that are long enough so you can install a new while the old battery is still in circuit.

I am really hoping someone has a Datron 1082 Service manual with schematics that they can steer me to, preferably a soft copy so I can better troubleshoot the unit. It might just need a new battery (plus a re-cal) to get it going again but I hate going blind.
