[601HP]

I've had a Battery Tender Jr. connected to my F350 diesel for several years. That truck has two batteries in it. The Tender continues to work well.

I've had another Tender Jr. connected to my wife's 1966 Mustang for several years. And it continues to work well.

I've had a Battery Minder (very similar to the Battery Tender Jr.) connected to the Cobra for several years. It continues to work well.

Both products sell in the $29.00 range, and are approx. 1.25 amp units. All 3 units I mentioned are generally connected to our vehicles for most of the year.
