Isn't going to do any harm trying to trickle charge it. However, your infrequent driving pattern is hard on battery life.

No. The starter motor will be the single biggest draw on any battery. However if the battery is a known problem, I'd fix the obvious first and then proceed from there.

Voltage - approximate charge of a battery (engine off)
12.60 V 100%
12.35 V 75%
12.10 V 50%
11.95 V 25%
11.70 V 0%

When the car is running and the alternator is working properly, you should see 13 - 14.5V as measured at the battery.
