Since we are on the topic of battery charging...

I purchased 2 new expensive 2400s for my starter box.

4 Questions :

1. Should I slow charge them for the first time - if so how and what amps/discharge
2. What amps / discharge should I use to charge them the night before an event?
3. Because they'd only get charged maybe once a month - should i completly discharge them to a particular voltage and leave them flat?
4. I have the option of 2Amp or 10Amp discharge on my charger - which shall I use?

Thanks
