I'll buy some things from HF but a battery maintainer would not be on the short or long list... prolly not jack stands either (maybe a jack though). I look to them mostly as an alternative for purchasing "one use" tools. Otherwise I purchase good/better brands.
As noted above, C-Tek makes the Porsche Charge-O-Mat II. Their 3300 model has a few more options than the OEM Porsche one at 1/2 the price - can be found easily on Amazon & ebay < $60.
Regardless, I wouldn't count on a maintainer from HF for anything other than maybe an old lawn tractor...... maybe...
Good luck
