will it charge a dead battery?

Yes it will. That was my problem. You have to do some special settings on the unit. Call the customer service number and they will give you the procedure. You can probably find it online also.

Yes. It will charge either via a compatibile USB charging plug or by using a standard micro USB cable. The charging speed depends on the output amperage of the plug. Best charging is at 5V / 2A

Completely dead? If it is broken (dead) no, ... otherwise if the battery is completely depleted it will work. This has happened to me a few times. It also recharges very rapidly, ... about 2 hours for a full charge.

From our experience this charger may recharge a battery if it still has a little life in it. It will not recharge a completely dead battery.

Yes. But be careful, once the charge is complete (red light turns on) make sure to unplug it or it will overcharge and ruin the battery.

Yes, as long as the charger recognizes a full charge. Otherwise you will need to manually monitor voltage. These type of batteries are used in applications w/ built in charger, so if battery is dead a new battery is likely needed.

Yes, just like any other charger but you can leave it hooked up after charging is completed. If the dead battery is no good, nothing will help.

A charged battery for a car can produce very high current, like when starting a car. Connecting this thin cable between the 2 batteries can get very hot and cause a possible fire. With out knowing any more details, it is safer to charge the dead battery with a battery charger.

I should think so. So long as the battery fits into the battery slot, it should charge.

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!

a fully dead battery might have other problems, like shorted cells, or something else that might affect it's ability take a full charge. But as far as the battery charger goes it should charge overnight, it's best i've ever had

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.

If it is totally dead it may not work. For dead batteries a manual charger works better.

I'd say no it shows it's charging but if it's near a dead battery it isn't even strong enough to keep it from shutting down so no it won't charge as fast as it uses or even close .

It should, it is rated for 12volts. It might take all day, but should charge it.
