will it charge a completely dead battery?

I don't know for sure. I have never tried. To the best of my knowledge a completely dead battery is just that, dead, and will never give satisfactory service again.

No... but if you are talking about a battery that had the lights left on overnight and 'dead' it will not charge if it is below (I think 2 volts) some minimum voltage left in the battery. It IS very frustrating because the older 'not so smart' chargers would at least try to charge a dead battery where these smart ones won't work at all. I faked one out once by connecting a small motorcycle battery to my dead car battery and fooled the 'smart charger' to start working and then put the motorcycle battery back. Battery was fine after about 6-8 hours of charging.

I could not get it to work at all, The indicators on the side did not show it was charging nor could I choose the type of battery.

I guess you have to define completely dead. Will it charge a battery that has been completely drained overnight by leaving an accessory on? Yes, matter of fact it has a automatic De-calcify mode that helps make batteries last longer. Will it charge an 8 year old battery that died because of below zero temps? no, no battery charger will.

Not only will it not jump start a dead battery, if the battery is too dead, it will not even charge it, as it needs to "see" a minimum voltage before it starts to charge.

this battery charger would only charge just a little bit, and if the batteries were completely dead, it wouldn't do anything at all...eventually it got so bad this charger wouldn't work at all. One of the worst purchases I've made in a while...take my advice, spend the money and purchase a dedicated charger for your golf cart, it's worth it!

Yes it will charge the battery in question, it will also charge up to 6 cell battery. You shouldn't need any other connectors as it comes with a wide verity.

No it will not charge until i plug the usb cord to the back up battery and it will charge for a quick second before it turn off.

The wattage of this unit is too low to charge a completely dead battery. It will only maintain a battery that is already charge,preventing your battery from getting drained even when parked for sometime.

I would say yes to deep cycle battery charging,no start mode.it won't charge a completely dead battery,it has to have at least 7 volts I think.i thought that was odd but that's the way it is.

no it wont actually start a car but it will re-charge a dead car battery in an hour or so.

Without knowing the state of your battery it would be hard to say. Try the recondition button to see if you can get the battery to work, press the large button until recond light is lit. It takes a while to recondition the battery. Modern battery chargers will not charge bad batteries. If you started with a dead battery, then recondition may help. If the battery was okay then you have a bad unit. I would try it on a good battery before sending it back

Yes it does, as long as it isn't 100% dead. If it is let it charge a few minutes first

It would but would take several hours but it has charged a dead battery for me a few times. If it is a totally dead battery it might not register in the charger.

It will charge a dead car battery with in 13 hours depending on the battery's capacity. It will not jump start a car though.

It might, depending upon battery size and how discharged it is - if it is totally discharged, nothing may bring it back, but if it is just really low, you might try to pre-charge it with a regular charger and then maintan it ( which is what the Tender is for) wihe the Battery Tender.Remember, it is only 1.25 amp and I would think you might need at least 2 amps for charging very weak batteries

If your phone is completely dead it will not bring it back to 100% but will give you around 65-70% ! Long story short it will charge your phone!

Hi! I did not try, but its capacity is 6000 mAh, so it should fully charge &lt;= 6000 mAh battery notebook. My notebook has 5200, for example.
