That is a good price on 12 V floating chargers, though I am not a fan of HF, just sayin,,,,

Me either but a buck is still a buck. I've even stepped so low as to eat zucchini so ordering from HF is not the end of the world.

I just bought a battery maintainer from Walmart for $20.

One note on using a battery load tester, you need to charge the battery first before you test it. Otherwise it will test bad.

I don't use those felt disks and don't like that battery terminal spray. If I find corrosion, I remove the cables and dip the ends in water and baking soda. I clean the posts with this mixture also. Dry them off, clean with a worn out old plumbers brush, then smear some wheel bearing grease on everything. Put the cables back on, tighten and smear the grease around on the bolts. I hardly ever have to deal with any corrosion. I only have the vehicles and the lawn tractor but I start that often in the winter as I use it for my transportation around the property. Usually started every couple of weeks, any time of year.

I agree with Robert_p43. But also make sure the rest of your battery is clean. Dust and oil mist can set on your battery top and create a voltage drain between the pos and neg.

As for corrosion on the posts or side terminals, what I've found works good for me is antiseize. I do the same as using grease like Robertp43 described. I make sure there is a good thick coat around the base of the posts in case the batt starts gassing out around the post. This is usually what causes corrosion to begin with. After attaching the clamps I liberally coat them w/ antiseize. It works as good as grease and is conductive.
