Shop quality charger

I wanted a shop quality charger. This one meets that standard. The variable charging modes make this unit. I had a parasitic draw on a brand new battery causing it to degrade and with one of the modes it brought my battery back to life. I'd recommend this unit for the home shade tree mechanic.

Just select what battery you have, and hit the charge battery button. Pretty simple. Plug it up, and CcHHHHAAAAAARRRGGEEE!

Stops changing at 12 volts, my own alternator keeps it at 14.8 volts. Jump option does not seem to perform as advertised and the rebuilding battery option, which used to work years ago; now doesn't seem to do anything. it also comes with assembly requirement, for as expensive as it was and the packaging it came in and with i should not have to assemble

Great for most needs but one.

If you want a great jump starter, charger or even a great battery maintainer or rejuvenator, this is your charger. If you are trying to charge a truly dead battery with very low voltage, this one falls short, not even recognizing that it is hooked up to the terminals.

Unsure

Never used it. Too many negative comments about this item. Also seems the circuit board is loose…peeking through the vent on unit. Decided to return than take a chance with it.

Didn't work-

This won't change the battery in my van. I also just watched the video on youtube, and the man tried twice to start his corvette, and it didn't work.

reply from Stanley12Volt

This unit is a fully automatic battery charger and requires that a battery contains at least 2V remaining in it, so the unit is able to detect and connect to the battery properly. If the battery is completely depleted, this unit may not be able to charge it. It is recommended to have depleted batteries checked at local automotive store to ensure they are in functioning condition. If further assistance is needed, please contact Baccus Global Technical Support at 877.571.2391 or email at CustomerService@Baccusllc.com
