You will need to plug it into a wall outlet. There is no battery to charge.

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

no as long as its a 12v battery it will charge it, the bigger it is the longer it will take.

It does charge. It charges the OEM batteries and the original battery as well. Its more compact and handy than the original charger...

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.

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

No. And reading the instructions makes it clear that you should use only the cord to charge the battery. It is recommended to charge the battery only when it is completely dead to extend the battery life. One reviewer confirmed this trimmer won't run with a dead battery, even when plugged in to the charger cord.

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. It is also a battery maintainer which means it charges the battery. You should regularly test it to be sure the battery is good and probably replace the battery every three years or so.

Most "smart" chargers will not charge a completely dead battery. They require some minimal charge to start charging. We sometimes use a set of jumper cables hooked between a good battery and the one needing charging to get the charger started, then unhook the good battery and let the charger work

It will but a trickle charge. Meaning if you are not using the battery it will charge but if constantly trolling it will not keep up specially on high troll settings. Hope this helps!!

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 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.

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

NO...this is a battery charger. You will need to dismount the battery and take it to a location where this is power for the charger to do its job.

unless the battery is incredibly wide, maybe 6" wide, and the battery contacts are in the middle of the battery instead of on the edge of it, then it will charge it...so the answer is basically i'm guessing yes.this charger is extremely adaptable as to form factor of battery...and the charging pins are adjustable so that as long as your charging contacts on the battery are are about 2" or less away from the edge of the battery (and most are only about 1/4 to 1/2 inch away) then you can charge the battery as long as it is the quadrilateral slim kind of battery.
