🔋 Cen-Tech 60581 Car Battery Charger Manual with Engine Start, 10/2/50 Amp/12V Review

Four of them were blown up by KV. Read the instructions. If you want to change settings while charging, disconnect it from the mains and, if necessary, also from the battery. Then connect the battery after changing the settings and connect it again. I'm looking for another one to buy this time. Take a second elsewhere and change the setting while it's plugged in and something inside is gasping. They don't make them like they used to.

Works, a bit noisy and sounds like it won't last long. The one I had was sent back to Harbor Freight after just two weeks. Used three times before it broke. I am sure that I had an isolated case with such a failure. The device boiled out the third battery overnight at the 15 amp setting and was unable to charge the second battery. The charger charged the first battery correctly. I have four vintage cars and when the old one broke down I tried something less expensive and imported but nothing…

I used this charger maybe 3 times and the 4th time it smoked and shorted out. I was actually trying to find out if an ASKnock 3rd party could help with a pro rata review or an exchange of which I would pay the difference if a reasonable offer was made. ASKnock will not accept any offer or payment for a defective product which I believe is a charger. I bought the charger in March 2014 and I understand that it cannot be exchanged or returned. Bad CUSTOMER SERVICE, like good or bad credit, will…

I bought 3 of these and kept sending them back, couldn't figure out why they charge my dead battery or show no connection when the crocodiles are clicked together (to check whether it was included). I finally read where Smart Tech won't charge a completely dead battery. That . . "Safety feature" so you don't accidentally create sparks. So you're screwed if your battery dies completely. The trick I've heard is to connect another 12v battery to trick the charger into thinking it's a half dead…

I bought this charger at the cargo port (automatic is rubbish) it made it so safe it rarely worked. But then in frustration I removed the automatic computer and installed 2 of the 20 amp diodes, ring side to the main transformer terminals, black side of the diode to the ground plane. I bought diodes from Revain. Now it's a great charger, just like the old days but better. 2 amps now = 10 amps, (max 8 hours charge) max voltage 14.43, choose 10 amps = charger 20 amps, (max 4 hours charge) max…
