ALSO, bringing a battery back from the dead is better performed with 1 hour at 2 amps and 1 hour at 10 or more with an analog charger. Repeat as necessary. Once fully charger, i.e. the meter drops to zero. Put it back in the frunk and try to start it.

Get a Battery Tender plus and use it religiously if you plan on not driving for more than a day. Leave the permanently attached to the terminals/pigtail extended outside the frunk. It has a rubber cover to protect it from corrosion and you can connect it w/o having to open the lid each time.

Those fancy digital ones are worthless with totally flat batteries. BTDT, got the tee shirts to prove it.
