Stupid question but is there any possible way to get to the vehicle at least
once a month or can someone you know and trust gain access to the car at
least once or twice a month??? Unless you have a problem with your battery
and/or charging system, having someone start the vehicle and let it run for
roughly 10-15 minutes seems like an easier solution.

This is not ham radio related but I know you guys have the answer.

I need to store a car unattended for a winter in the midwest. And I
want to put a tricke charge on the battery.

I'd rather not buy a fancy trickle charger because it would probably get
stolen. On the other hand I have a vast array of wall wart
transformers.

If I connected one of these transformers how many milliamps should it
put out at 12V? Or rather what's the least current that would do the
job?

It seems that lead acid batteries can dissipate too much current as
heat. In other words I could probably feed it one amp continuously.
But would 100 mA at 12V do the job? I'd hate to lose a 1-Amp wall wart.

Thanks for your help.
