Unboxing and initial review of the Viking 4 AMP Battery Charger/Maintainer from Harbor Freight. Retails for $37.99, before any discount. Is this charger worth the money?
I just bought this charger to maintain the AGM battery in my 2013 Cadillac CTS-V. So far so good. It is not my daily driver so she only sees the road maybe two or three times a month.
What does stupid video everybody knows how to use it. You’re supposed to measure the battery voltage then you’re supposed to measure how much amp that thing is pushing into the battery see if it is bubbling after 10 hours that is totally useless.
