Harbor Freight Automatic Battery Float Charger Review

Cen-Tech charger for long term floating maintenance of a rarely used battery. I test current delivery to ensure this will not ruin or over charge your batteries. Rated for 0.5A (500mA) this unit will limit the current to a lower trickle value once the battery is at full charge. I measured 125mA after 30 minutes on a fully charged car battery. Was $8 in store but had a $5 coupon. Tremendous bargain compared to the Walmart units. Harbor Freight does it again:
