Title: Where is the TEK 2245A backup battery?
Post by: AndersJ on February 21, 2016, 11:45:25 am

Thinking I might need to replace the the battery after about 28 years of use
I opened up to measure the battery voltage.
The voltage on the two diodes is 3.3 Volts, which I consider good after such a long time.

BUT, where is the battery?
I cannot find it.

On a 2246a it's on the backside of the processor board. You have to remove the board to change the battery.

Found it, thank you.
The battery date code is 1988, fantastic quality.
