If one accepts there is some risk changing the battery while preserving the data, one has two choices. 1) Do as you say and leave the battery, preserving the cal data. This however risk the battery leaking at some time. 2) Change the battery, losing the cal data, but virtually eliminating the risk of leakage. To me at least, the path of least risk is the one to take. I suspect if one put a power supply in parallel with the battery with a 10 k resistor in series, then the 10 k resistor would not drop enough voltage to lose the ram data, but if it was accidently shorted the current would be limited to a few hundred microamps. That's unlikely to do any damage I guess for a volt nut, preserving the cal data is more important than it is to me. Not damaging the meter is higher on my priority list.
