Battery tender chargers

[theholycow]

I have a history of causing early death to lead acid batteries. I currently have 3 batteries that are mostly unused. One gets used every month or two, and will be used daily in the winter. One will remain mostly unused until next spring. The third is a spare. I want to keep them all from becoming useless but I only have one smart charger.

Will the $8 "Automatic Battery Float Charger" from Harbor Freight do what it says it will do?

Has anyone used it? Will it "Maintain the charge of your 12-volt battery without overcharging"?

I have similar problems... I bought one of these at Grainger:

It works very well, I use it on my Buick.

I was planning on buying the OEM Harley charger (About $25) for my bike because the bike is already pre-wired for the Harley charger, so I wouldn't have to do anything but plug it in.

Yikes. My batteries cost about as much as that charger. I'd be better off taking my chances that I'll remember to switch my one charger between them.

Well, I wrote it off as a business expense... A fringe benefit of buying stuff @ Grainger. The battery in the Buick is nearly $100. I buy the best & biggest battery Wal-mart carries, and I always seem to kill them stone dead before the warranty runs out. I bought one 10 years ago, and have been getting free replacements ever since.
