Good afternoon....i bought my 1st boat in December and it has been winterized and shrink wrapped....i was told in the spring to charge the batteries when im ready to get her ready.....what kind of charger do i need? Any auto battery charger or one specific to marine batteries?

Any name brand smart charger for STD/AGM/DEEP CYCLE with maintainer mode will do

In the spring, check fluids and do prechecks, then Fire it up if it can, and "next" winterization, place the batteries on maintenance chargers for the winter

I unhook mine and place them on cheapo harbor frought battery tenders....

Yes,...i will definitely do that....i bought it in December and the marina was nice enough to winterize it and shrink wrap it as a courtesy.....mechanic said he unhooked the batteries and in the spring just “ charge em up” and i should be good to go....guess i have to wait and seemwhat kind of batteries are under there.
