Charge batteries while amps connected?

yes charges through the runs front front to rear ..wil charge any amount of batts u have ..it has standard gel and agm settings on it with digital display

when connecting the charger is there a sequence that needs to be followed, like which do you disconnect first positive or neg, or which do you disconnect first.

doesnt really matter bc when u hook it up the lcd just comes on it doesnt start charging yet..u have to select the mode and what amp charge u want

i dought the amps would but i just wanted to be sure, some items can't handle 120 volt wall outlet. better safe than sorry.

Open up any electronics, clocks, radios, home amplifiers, TVs, battery chargers, etc... they all have AC to DC inverters inside because none of them can operate directly off of alternating current. The only device that are not affected by AC or DC is incandescent lightbulbs.

No need to worry long as the charger is outputting DC within the operating range of a vehicle while under load.

thanks again, i saved it on my watchlist, i could not find an ho alt for my 2010 Mazda cx-9 so this might work for me and have the alternator not workign too hard to charge the battery

i always disconnect ground first, then power. then do the opposite when re connecting.
