Good morning: Has anyone used a Li-ion 18650 for battery backup on a CLX 5550. i'm working on a trainer that will be power off for fairly long periods of time and want to preserve the program in memory with the backup battery. The battery voltage on a 1756-LM55 is 3.6 and the 18650 is 3.7. It would be easy and inexpensive to harvest 18650's and build a battery pack.
