Walmart still offers the Schumacher 1.5-amp Slow Charge Battery Companion
, model no. SEM-1562A, for $19
. Choose in-store pickup
via Site-to-Store to avoid the $1.97 shipping charge. (Amazon
ships it for the same price for Prime members.) That's tied with our mention from last week as the lowest price we've seen for this charger without rebate hassles. (It's a current price low by $5.) Sales tax is added where applicable. This automatic battery charger maintains a battery's charge for vehicles that aren't used every day. It features reverse-polarity protection for both 6- and 12-volt batteries.
