I have a 2003 Mach 1 Mustang that is in storage on a CTEK trickle charger. The main battery stays fully charged at all times. The 520T has been upgraded to a 7AH battery. Will the 7AH backup battery stay fully charged as well with the trickle charger or does the 520T require driving the car to charge the backup battery? My alarm and backup battery are stealth installed so I can't easily check with a DVOM. Thanks in advance!
