How about a charger that has a supply mode? Meant for using when changing your battery but don't want to lose any of your car's settings. Would this work?
My CTEK 7002 has a supply mode: |
Looked up & their site says
Unique Supply and Recond mode
The Supply mode serves as a power supply unit that can run 12V equipment up to 7A. When changing a battery, important settings will therefore not be lost. The unique Recond mode restores the power capacity in a stratified battery, prolonging its life. The stratifying process starts after just a few deep discharges of the battery.
