Is this product for charging up your battery when it's dead? Or is this for something entirely different? Does it charge the battery?

No this product is only for monitoring battery performance and drains. It can tell you if your battery is running down and if you have parasitic drains that require attendance. But it does not charge your battery. I hope this helps!

Yes it charge your battery. Would show you a picture but dont know how to show image on here.

I would say yes as long as the battery isn't totally drained. The battery needs to be charged because it's a maintainer to keep a battery fully charged all the time! I think it's to small to charge a totally dead battery. The battery tender only puts out 1.5 volts and a regular battery charger puts out 12 volts to charge a totally dead battery.

Basically an old wive's tale at this point. Modern chargers mostly detect when a battery is full and stop charging (or drop back to just trickle charging). I wouldn't worry about it unless a manual for a device specifically says to disconnect the charger after a full charge. There's so much mythology and repeated nonsense out there about batteries, chargers, and how they work!

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.

Yeah, I saw where it said "drained" battery, but while researching these types of rechargers I saw another one that said "recharges drained batteries" but a few sentences later says, "don't use on discharged batteries" which I'm assuming means don't use this on dead batteries. Why can't they just SAY this works on completely drained batteries or not? Or am I just being too cautious? I'd hate to get this and have someone I love depend on it getting them out of a jam only to find out that welllll, it's not QUITE that good, yanno?

It's suppose to be plug charging when you are not using it so when you need it it's fully charge, but the battery don't hold charge anyway so it doesn't matter. I throw away mine, it's not worth it.

It stops charging your battery when the battery reaches full. It does not drain the battery prior to charging. I use mine for my 14.4 B & D tools. Does the job it was intended for. Hope this helps.

these things are a litte quirky, sometimes I hit the buttons to change from 3 amp to 12 amp and it resets it when it's stuck. Also- if you have time- let it's do it's magic- I think it's conditioning the batteries by taking forever sometimes- end result- it can make old batteries take full charge and extend their life, sometimes mine will take 12 hours to get full charge. If you have the time- I suggest letting it's do it's thing. I call it the jedi mind master charger- who knows how it works- but it works

This product is not to charge a dead battery, it's to maintain the charge during long periods when you are not going to use your motorcycle.

I use it as back up to my iphone when it dies. You first have to charge the charger, and keep it turned off until your phone gets low on battery, then turn charger on. Make sure the iphone is securely set into the case. It may take a minute to engage, but it will bring your iphone back to life. It will make occasional beeping sound, indicating its working.

The question posted by Barbara Kennedy was "how fast does it work?". This is a battery maintainer or float charger. It is not suitable for recharging a depleted or drained battery so charge time is not normally discussed relative to this product. If you need a proper battery charger there are many better suited to the task than this product which is aimed at keeping full charge in a battery that is used in a vehicle which is not frequently used.

It is a small charger for a small battery It will charge a bigger battery but will take a long time .I would get a bigger charger.

For me, yes. I use it to charge Eneloop batteries for my DSLR flash. But I've also used it to recondition and refresh other, older NiMh batteries, and it can identify which are no longer worth recharging. Other chargers tell you nothing. It's like the difference between a check engine light and a OBD reader. If you're comfortable with idiot lights, don't bother.

You can plug it in to recharge it, and I have used it while plugged in. I believe the instructions say not to do that, but it works.

It's rechargeable so you can plug it in when it's dying. My battery lasts 3 hours at the most. It might be a defective one, or that might be normal. I am not sure about that at this point.

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.
