  • Bank Failure Noted - Buy Something Else
Style: Charger
This thing can not handle 4 batteries at once. I try to read reviews before I buy and take a look at low rated reviews but didn't see the common bank failure noted or that would have had me suspicious. I too suffered the #4 bank failure but then could make it move to any of the others simply by moving the leads. Spent 1 day trying to make sense of this and is was all a waste, other than a battery charge which any machine can do. I wanted 4 bank charging, this cannot do it. My boss is understanding and told me to never buy Schumacher again. We got a Carlyle by Napa and it works wonderfully. ... show more

  • Must have in a shop
Style: Charger
This product saves time and money if you deal with batteries on a daily basis. Not only does it charge 4 batteries at once it can also recondition them as well. In doing this it will let you know if they cant be reconditioned and the battery is bad. The price is great compared to somewhere like Oreilly Auto Parts beat the price by a couple hundred dollars. Great product for backyard mechanics as well or just the average homeowner would purchase again. Product is small and very easy to use. ... show more
