The Big thing about an optima is thgat you do not chargeit wiht a charger. If it discharges, you simply jump it with another car or you will fry the battery.

My father charged his and we had to replace it afterwards.

We have no problems using a power booster on his car because it sits for months before he drives it again.

The boat can sit for months with an auto bilge pump on, and we can go and it will fire up almost instantantly, of course we always keep the battery power booster with us just in case.
