Since I now have a mix of 6 and 12 volt batteries to tend to, I searched for a charger/tender that would cover both voltages.
I came up with this:
Sold at Sears. It is Item# 02871219000 Model# 71219 for $29.99.
Its not as fancy as a 4 stage charger/float, but it has its merits:
$30 less than a Deltran Battery Tender Plus
Comes with a clip on, screw on and cigarette lighter connectors
3 year exchange warranty at ANY Sears store
Its DUAL VOLTAGE.. can charge/float either 6 or 12 volt batteries! This is the biggest reason I got it.
With the 3 included connectors my battery maintenance got a lot easier.
The alligator clips go on the gpw or CCKW for 6V
The bolt on connector goes on my Suzuki C50 for 12V
The cigarette lighter connector saying in my Durango.
Great deal for only $31!
