OK, there are dead battery topics - I searched. This one about trying to troubleshoot a battery issue from 5000 miles away. I'm away from home until mid November, we have people watching our house, and one of the things I've asked it to start the car 2x per month and drive it. They called me to say it's dead. Here is where we are:
1. 2006 V50 2.4. Battery 5+ years old
2. Car stored on Battery Tendor Junior trickle charger (steady red light should indicate that it seems to be charging...but not green that says charged.... or not flashing red that means not-chargeable)
3. Key is now stuck in ignition
4. Car "dead". Nothing at all
5. Attempted to start it with a jump-box (nothing happened)
I'm trying to walk our friend through this step by step. I'm wondering if its simply a dead (old) battery?
1. I think battery tender "junior" may be too wimpy to charge a really dead battery?
2. would a better battery/tender charger help? (I worry that if battery is really at 0 volts, there is nothing I can do)
3. Or should we go right to replace the battery?
4. If replace, is it ok to let car sit in its current dead state for another 6 weeks? Or should I get car towed and have battery replaced (ugh. don't want to pay towing for something so simple but don't want to ask this friend to to take on replacing the battery.
