So far I've had no problem with this fix I've had the battery installed for over a year. I used a CR2032 battery, but it's not the best solution because the analyzer will try to recharge it. | So far I've had no problem with this fix I've had the battery installed for over a year.

Backup battery
Description
The 1240 and 1241 retain configurations in battery-backed RAM. In most instruments, the battery is a Catalyst Research 3440LP. Over time, this battery will deplete and unltimately leak. A leaking battery can destroy components, PCB traces and metal.
Fix
The old battery can be de-soldered and wires can be soldered in to connect a new battery. It is up to the user to decide what type of battery they will use, as long as the battery voltage is about 2.9 V. The new battery can be placed wherever appropriate.
