Cheap Float Chargers

Post date: Nov 24, 2012 3:47:38 PM

If you've been wanting a cheap float charger for 12V lead-acid batteries, look no further! Harbor Freight has 'em on sale today for $5 (normally $13). Put it together with whatever car battery you find on sale, one of those big used $20 AGM batteries from CARS, or whatever other batteries you have on hand, and you have a pretty inexpensive radio power supply. Note that even with a battery to buffer it, a cheap power supply *might* inject noticeable noise into your radio; if that is the case, shut it off when operating.http://www.harborfreight.com/merchandising-promotions/merchandising/2012-ise/11-22-12-after-thanksgiving-sale/automatic-battery-float-charger-42292.html
